Precautions
Basic Information
Before actually committing component mass-production situation, OMRON strongly recommends situational testing, close actual production situations possible. reason confirm that product will still perform expected after surviving many handling mounting processes involved mass production. Also, even though OMRON relays individually tested number times, each meets strict requirements, certain testing tolerance permissible. When high-precision product uses many components, each depends upon rated performance thresholds other components. Thus, overall performance tolerance accumulate into undesirable levels. avoid problems, always conduct tests under actual application conditions. GENERAL maintain initial characteristics relay, exercise care that dropped mishandled. same reason, remove case relay; otherwise, characteristics degrade. Avoid using relay atmosphere containing sulphuric acid (SO2), hydrogen sulphide (H2S), other corrosive gases. continuously apply voltage higher than rated maximum voltage relay. Never operate relay voltage current other than those rated. relay intended operation, coil polarity. Connect power source coil correct direction. relay temperatures higher than that specified catalog data sheet. storage relay should room temperature humidity. COIL AC-switching Relays Generally, coil temperature AC-switching relay rises higher than that DC-switching relay. This because resistance losses shading coil, eddy current losses magnetic circuit, hysteresis losses. Moreover, phenomenon known "beat" take place when AC-switching relay operates voltage lower than that rated. example, beat occur relay's supply voltage drops. This often happens when motor (which controlled relay) activated. This results damage relay contacts burning, contact weld, disconnection self-holding circuit. Therefore, countermeasures must taken prevent fluctuation supply voltage. other point that requires attention "inrush current." When relay operates, armature relay released from magnet, impedance drops. result, current much higher than that rated flows through coil. This current known inrush current. (When armature attracted magnet, however, impedance rises, decreasing inrush current rated level.) Adequate consideration must given inrush current, along with power consumption, especially when connecting several relays parallel.

DC-switching Relays This type relay often used so-called "marginal" relay that turns when voltage current reaches critical value, substitute meter. However, relay used this way, control output fail satisfy ratings because current applied coil gradually increases decreases, slowing down speed which contacts move. coil resistance DC-switching relay changes about 0.4% degree change ambient temperature. also changes when relay generates heat. This means that must operate must release voltages increase temperature rises. Coil switching voltage Source supply voltage fluctuates, relay will caused malfunction regardless whether fluctuation lasts long time only moment. example, assume that large-capacity solenoid, relay, motor, heater connected same power source relay, that many relays used same time. capacity power source insufficient operate these devices same time, relay operate, because supply voltage dropped. Conversely, high voltage applied relay (even after taking voltage drop into account), chances that full voltage will applied. consequence, relay's coil will generate heat. Therefore, sure power source with sufficient capacity that supply voltage relay within rated must operate voltage range relay. Minimum Must Operate Voltage When relay used high temperature, when relay coil continuously energized, coil temperature rises coil resistance increases. Consequently, must operate voltage increases. This increase must operate voltage requires attention when determining minimum must operate voltage given below reference when designing power source appropriate relay. Assuming coil temperature rise 10°C, coil resistance will increase about must operate voltage increases follows: Rated values Model LZN2 taken from catalog data sheet Rated voltage: Coil resistance: Must operate voltage: max. rated voltage 23°C coil temperature rated current that flows through this relay obtained dividing rated voltage coil resistance. Hence, However, relay operates maximum this rated current, i.e., 19.2 0.8).

Additionally, rated voltage light type power source, voltage fluctuation, changes coil resistance temperature rise. voltage higher than rated maximum voltage applied coil long time, layer short-circuiting damage coil burning take place. Coil Temperature Rise When current flows through coil, coil's temperature rises measurable level, because copper loss. alternating current flows, temperature rises even more, only copper loss, additionally iron loss magnetic materials, such core. Moreover, when current applied contact, heat generated contacts, raising coil temperature even higher (however, with relays whose switching current rated lower, this rise insignificant).

Changes Must Operate Voltage Coil Temperature Rise coil resistance DC-switching relay increases coil temperature rises) when coil been continuously energized, de-energized once, then immediately energized again. This increase coil resistance raises voltage value which relay operates. Additionally, coil resistance rises when relay used high ambient temperature. Maximum Must Operate Voltage maximum voltage applicable relay determined accordance with coil temperature rise coil insulation materials' heat resistivity, electrical well mechanical life, general characteristics, other factors. voltage exceeding maximum voltage applied relay, cause insulation materials degrade, coil burnt, relay operate normal levels. Actually, however, there occasions when maximum voltage exceeded compensate fluctuation supply voltage. this event, attention following points. coil temperature must exceed temperature that spool wound wire constituting coil withstand. following table shows wires often used coil. this table, coil temperature measured through calculation coil resistance.

Switching voltage (AC, When relay breaks inductive load, fairly high counterelectromotive force (counter emf) generated relay's contact circuit. higher counter emf, greater damage contacts. This result significant decrease switching power DC-switching relays. This because, unlike AC-switching relay, DC-switching relay does have zero-cross point.

Should heat humidity entirely high, relay's physical characteristics will likewise affected. example, heat rises PCB's insulation resistance degrades. Mechanically, parts will continue expand heat applied, eventually passing elastic limit, which will permanently warp components. Moreover, relay used extremely humid environment, silver migration take place. Exposure gases containing substances such sulphuric acid, nitric acid, ammonia cause malfunctions such faulty contacting relays. They also cause copper film corrode, prevent positive contacts between PCB's connectors. gases mentioned, nitric acid particularly damaging tends accelerate silver migration. counter-measure against exposure damage, following processes relay have proved useful.

Mounting Position Depending where relay mounted, function relay (and performance circuit which includes relay) adversely affected. relay malfunction mounted near transformer other device that generates large magnetic field, much heat. Provide adequate distance between relay such devices. Also, keep relay away from semiconductor devices, they mounted same PCB.

Vibration Shock Although itself usually source vibration shock, simplify prolong vibration resonate with external vibrations shocks. Securely PCB, paying attention following points.
Mounting Direction allow relay operate full capability, adequate consideration must given mounting direction relay. Relay characteristics that considerably influenced mounting direction shock resistance, life, contact reliability. Shock Resistance Ideally, relay must mounted that shock vibration applied relay right angles operating direction armature relay. Especially when relay's coil energized, shock resistance noise immunity significantly affected mounting direction relay. Life When switching heavy load that generates (generally, having greater impedance than that relay coil), substances spattered from contact accumulate vicinity, resulting degradation insulation resistance circuit. Mounting relay correct direction also important preventing this kind degradation insulation resistance. Contact Reliability Switching both heavy minute load with single relay contact recommended. reason this that substances scattered from contact when heavy load switched degrade contact when switching minute load. example, when using multi-pole contact relay, avoid mounting direction terminal connections which minute load switching contact located below heavy load switching contact.
Technical Information Relays
Mounting Interval When mounting multiple relays side side PCB, attention following points: When many relays mounted together, they generate abnormally high heat thermal interference between relays. Therefore, provide adequate distance between relays dissipate heat. When using relay, sure check minimum mounting interval. Also, multiple PCBs with relays mounted rack, temperature rise. this case, preventive measures must taken that ambient temperature falls within rated value. PATTERN LAYOUT Countermeasures Against Noise relay noise source when viewed from semiconductor circuit. This must taken into consideration when designing layout positioning relay other semiconductor components PCB. Keep relay away from semiconductor components away possible. Locate surge suppressor relay coil close relay possible. route wiring signals such audio signals that likely affected noise below relay. Design shortest possible pattern. method separating power source relay from other electronic components shielded patterns. Coating also case humid environments, coating recommended prevent insulation pattern form being degraded gases containing harmful substances. When coating PCB, however, care must exercised allow coating agent penetrate into relays mounted PCB; otherwise, faulty contact relay occur sticking coating. Moreover, some coating agents degrade adversely affect relay. Select coating agent carefully. Type Coating Item Applicability with relays mounted Good Feature

Precautions
BASIC INFORMATION
Before actually committing component massproductionsituation, OMRON strongly recommends situational testing, close actual production situations possible. reason confirm that product will still perform expected after surviving many handling mounting processes involved mass production. Also, even though OMRON relays individually tested number times, each meets strict requirements, certain testing tolerance permissible. When high-precision product uses many components, each depends upon rated performance thresholds other components. Thus, overall performance tolerance accumulate into undesirable levels. avoid problems, always conduct tests under actual application conditions. General maintain initial characteristics relay, exercise care that dropped mishandled. same reason, remove case relay; otherwise, characteristics degrade. Avoid using relay atmosphere containing sulfuric acid (SO2), hydrogen sulfide (H2S), other corrosive gases. continuously apply voltage higher than rated maximum voltage relay. Never operate relay voltage current other than those rated. relay temperatures higher than that specified catalog data sheet.
