Rish Relay 25x-PBx - Transducer Trip Relay
The transducer trip will accept an analog signal from most measuring transducers and transmitters in the form of DC voltage or currents. Inputs are monitored within the preset limits and in the event of the input moving outside these limits.

Principle of operation
The input current is fed through a resistor, and the resultant voltage is compared with a preset reference voltage from the set-point potentiometer.
Any voltage difference forms a command signal, which is fed via an amplifier to a double-pole changeover relay. As standard, the relay energizes at a high set point on a rising signal and de-energizes at a low set point on a falling signal.
