RS PRO Signal Conditioner, Current Input, Relay Output, 10 → 30V dc Supply

24Vdc Trip Amplifiers, Signal Isolator/Converters

Symmetric DIN rail mounting units with finger protected terminals designed for use in process control and instrumentation applications. Single or dual level trip amplifiers from a single Input.Each trip can be arranged so that the alarm condition can be above (high trip) or below (low trip) the set point, and that the relay can be either normally energised to de-energise in the alarm condition (fail-safe), or normally de-energised to energise in the alarm condition (non fail-safe).,signal Isolators/converter; this unit conditions the signal before sending it through an opto-isolated hybrid circuit. Input and output stages are power from separate secondaries of the dc/dc inverter to provide 3 port isolation
