APPLICATIONS
Industrial signal conditioning Industrial signal isolation Industrial signal filtering
There also number backplanes mounting sockets which provide complete signal conditioning solution users. Each backplane incorporates screw terminals field wiring inputs outputs cold junction sensors thermocouple applications. These signal conditioners designed provide easy convenient solution signal conditioning problems both designers users measurement control applications. Typical uses include microcomputer-based measurement systems, standard data acquisition systems, programmable controllers, analog recorders dedicated control systems. series modules ideally suited applications where monitoring control temperature, pressure, flow, rotation other analog signals required. Series modules backplanes approved Factory Mutual (FM) Series modules approved Canadian Standards Association (CSA) Class Division Groups locations. These approvals certify that Series suitable locations where hazardous concentration flammable exist only under fault conditions operation. Equipment this category called "nonincendive" they need special enclosures other physical safeguards. series modules backplanes have been tested passed stringent heavy industrial requirements European Union's electromagnetic compatibility (ENC) directive EN50082-1 EN50081-2. When used according installation directions (refer series User Manual), errors caused EMI/RFI interference will less than 0.1% full scale measurement range field strengths frequencies GHz.
PRODUCT OVERVIEW
Series represents innovative generation cost, high performance plug-in signal conditioners. Designed industrial applications, these modules incorporate highly reliable transformer-based isolation automated surfacemount manufacturing technology. They compact, economical components whose performance exceeds that available from more expensive devices. Combining 1500 continuous isolation, +0.05% calibrated accuracy, small size cost, Series attractive alternative expensive signal conditioners in-house designs modules potted identical pin-out size (2.27" 2.32" 0.595"). They mixed matched, permitting users address their exact needs, "hot swapped without disturbing field wiring power. isolated input modules provide outputs accept type thermocouples. These modules feature complete signal conditioning functions including input protection, filtering, chopper stabilized drift uV/oC amplification, 1500 isolation, sensor excitation when required. modules feature excellent common mode rejection meet industrial transient surge withstand specifications.

5B32 GENERAL DESCRIPTION
5B32 single-channel signal conditioning module that amplifies, protects, filters isolates analog input. module measures process current input signal 4-20 0-20 reading voltage across external precision resistor (supplied) generating output Extra current conversion resistor available accessories (See Model AC1362 Accessories section). Note that 5B32 module circuitry withstand input screw-terminals, thereby shielding computer-side circuitry from field-side overvoltage conditions. addition, 5B32 Series modules mix-and-match swappable, inserted removed from socket same backplane without powering down system. chopper-stabilized input amplifier provides drift stable gain. amplifier input, stable, laser-trimmed zeroscale input offset subtracted from input signal zero-scale value 4-20 range. user convenience, zero optionally factory-set meet custom needs, This allows suppression zero-scale input value many times larger than total span precise expanded-scale measurements. Internal multi-pole lowpass filtering with four-Hz cutoff (3dB) enhances normal-mode (noise signal) commonmode (noise signal return) rejection 50/60 enabling accurate measurement small signals high electrical noise. series output switch eliminates need external multiplexing many applications. switch turned active-low enable input. switch times, enable-input should grounded power common 5B01 5B08 backplanes.
