Transducers
DC Reverse Transducers [Non-insulated]
DC reverse transducers input DC voltage (or current) and output DC voltage or DC current
inversely proportional to the input; for example, as the input signal increases from 0% to
100%, the output signal decreases from 100% to 0%.
Applications
Monitoring of deviation amount in combination with devices such as a position
detection sensor or temperature transducer
To create a fail-safe arrangement in the event of losing control power supply
