PRODUCT DESCRIPTION

The GT-AR series analog to relay module accepts an analog

voltage or current signal and controls either 2 relays

(GT-AR-2) or 4 relays (GT-AR-4). The input signal has three

jumper selectable ranges for either 0-7.5 Vdc, 0-15 Vdc

or 0-20 mA. Each relay has an independently adjustable

setpoint which is set with a multi-turn pot.

Each form-C relay activates when the input signal is equal

to the trip setpoint and deactivates when the input signal

falls below the setpoint by a deadband amount. The

deadband is also jumper selectable for 1, 3, or 5 of the

range.

Features include a regulated power output that can be

used to power a transducer or a resistance input, topadjust

trim-pots for setpoint adjustment, an LED power

indicator, status LEDs for each relay and 10 Amps form-C

relays. The product comes with standard snap-track for

easy mounting.
