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 double pole changeover relay. As standard, the relay energises at high set point on a rising signal and de - energises at low set point on a falling signal.
