SLIMPAK® G118-0002 RTD Input Field Configurable Limit Alarm Provides Relay Contact Closures at a Preset RTD/Resistance Input

ULTRA SLIMPAK® G118-0002 G118-0002 RTD Input Field Configurable Limit Alarm Provides Relay Contact Closures at a Preset RTD/Resistance Input Level Description Benefits The Ultra SlimPak G118 is a DIN rail mount, RTD input limit alarm with dual setpoints and two contact closure outputs. The field configurable input and alarm functions offer flexible setpoint capability. There are up to eight temperature ranges available for each RTD type to ensure accuracy and maximize setpoint resolution. Field Configurable Ranges for Platinum, Nickel and Copper RTDs The G118 is configurable as a single or dual setpoint alarm, with HI or LO trips and failsafe or nonSetpoints Programmable HI or LO, Failsafe or Non-failsafe Ultra Slim Housing for High Density Installations LED Trip and Input Indicators Flexible Power Supply Accepts 9 to 30VDC 30VDC ASIC Technology failsafe operation. Also included are adjustable deadbands (0.25 to 5% of full scale input) for each setpoint and a flexible DC power supply which accepts any voltage between 9 and 30VDC 30VDC. Diagnostic LEDS The G118 is equipped with three front panel LEDs. The dual function green LED is labeled INPUT and indicates line power and input signal status. Active DC power is indicated by an illuminated LED. If this LED is off, check DC power and the wiring connection. If the input signal is more than 110% of the full scale range, the LED will flash at 8 Hz. Below 0%, it flashes at 4 Hz. Two red LEDs indicate the relay state for each setpoint. An illuminated red LED indicates the tripped condition. Output The G118 is equipped with two SPDT (form C) relays, rated at 120VAC 120VAC or 28VDC 28VDC at 5 Amperes. Each of these relays is independently controlled by the field configurable setpoint and deadband. Operation The field configurable G118 limit alarm setpoints can be configured for HI or LO, failsafe or nonfailsafe operation. Each of the setpoints has a respective HI or LO deadband. In a tripped condition, the setpoint is exceeded and the appropriate red LED will illuminate. The trip will reset only when the process falls below the HI deadband or rises above the LO deadband (see Figure 1). For proper deadband operation the HI setpoint must always be set above the LO setpoint. In failsafe operation, the relay is energized when the process is below the HI setpoint or above the LO setpoint (opposite for non-failsafe). In the failsafe mode, a power failure results in an alarm state output.

Dynamic Deadband Circuitry in the G118 prevents false trips by repeatedly sampling the input. The input must remain beyond the setpoint for 100 milliseconds, uninterrupted, to qualify as a valid trip condition. Likewise, the input must fall outside the deadband and remain there for 100 milliseconds to return the alarm to an untripped condition. This results in a "dynamic deadband" (based on time) in addition to the normal deadband. Configuration Unless otherwise specified, the factory presets the Model G118 as follows: Input: Range: Output: Trip: Failsafe: Deadband: Platinum (100 Ohm) 0 to 250°C Dual, SPDT A:HI, B:LO No A, B: 1.0% The DC power input accepts any DC source between 9 and 30V; typically a 12V or 24VDC 24VDC source is used (see Accessories). For other I/O ranges, refer to Tables 1 through 3 and reconfigure switches SW1 and SW2 for the desired input type, range and function. 1. After configuring the DIP switches, connect the input to a calibrated RTD source or a resistance decade box and apply power. Note: To maximize thermal stability, final calibration should be performed in the operating installation, allowing approximately 1 to 2 hours for warm up and thermal equilibrium of the system. ommended) of sufficient voltage, and a 47 ohm, 1/2W carbon resistor. For DC inductive loads, place a diode across the load (PRV > DC supply, 1N4006 1N4006 recommended) with (+) to cathode and (-) to anode (the RC snubber is an optional enhancement).
