A low input impedance signal conditional for use in process control and instrumentation applications designed to condition the signal before sending it through an opto-isolating hybrid circuit.
The input and the output stages of the signal conditioner are powered from separate secondaries of the of the dc/dc inverter maintaining the 3 port isolation.
A symmetric DIN rail mounting unit with finger protected terminals and dual voltage operation the trip amplifier can be arranged as follows:

The alarm condition can be above (high trip) or below (low trip) the set point
The relay can be normally energised to de-energise in the alarm condition (fail-safe)
normally de-energised to energise in the alarm condition (non fail-safe)
