Honeywell GM-JR

Honeywell GM-JR

The GM-JR is a unique and practical montior readout/ alarm device that offers a variety of configuration options. It provides a calibrated 20 segment LED bargraph up to 100 ppm, alarm and fault LED's, single trip point in 5% increments and relay outputs. It has an easily adjusted setpoint and relay output in either configuration polus 4/20mA output in the "feed-through" design. With ists own plug-in power supply the GM-JR sensor combination provides an economical answer fo local concentration level information and control capability.

System Specifications

Electrical Power 15-24 VDC regulated
Signal Input 4/20 mA precision differential input allows this unit to be mounted remotely and powered from sensor power (internal resistance drop is 100 ohms).
Maximum Current Draw 300mA (In standard configuration and no upscale indication, the standby current draw is 100 mA)
Display 20-segment LED bargraph, with a bottom segment that flashes to indicate power up delay, and lights continuously to indicate that the power is on
Trip Setting 5% increments by use of shorting tab
Alarm Indication Red LED
Fault Indication White LED (at 1.4 mA or below)
Accuracy LED readout provides 5% of full scale resolution. Trip accuracies at these 5% increments are within ± 1% of set point
Time Delays Alarm Delay is 10 second delay on, 30 second delay for restet after alarm condition clears
Power Up Time Delay On application of paer the alarm relay will be held in a normal state for one (1) minute to allow the sensor to stabalize
Relay Alarm Output Relay is rated at 0.5 amp at 24 VDC or 24 VAC, 0.25 amp at 120 VAC. Relay will trip on Alarm and Fault conditions
Operating Ambient Temperature Range 0° F to +120° F
Stroage Temperature Range —40° F to +160° F
Operating Humidity 5-95% Relative Humidity, non-condensing
Enclosure NEMA 1, gasketed, 16-gauge steel
Weight  3 lbs.
Dimensions 6" high x 4" wide x 3.5" deep
Cable Requirements #18/3 shielded cable (Belden #8770) for runs up to 1,000 feet. High current draw sensors may require larger cable. Contact Honeywell Analytics for details.
