Principais características

2 channels
5-port 3.75 kVAC galvanic isolation
Output voltage > 18 V to I.S. area
Active current loop detection
Universal supply by AC or DC


Voltage supply with safety barrier for the supply of equipment mounted in hazardous area.
Voltage supply with failsafe detection of active current loop from 2-wire transmitters mounted in hazardous area.

Mounted vertically or horizontally on a DIN rail. Up to 84 channels per meter can be mounted.


PR5420B has a relay with change-over contacts available in the safe area. When the loop current is within the defined limit, the relay is ON.

Supply and outputs are floating and galvanically separated.
