Ex power supply
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
Application
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.
Technical characteristics
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.
Mounting / installation
Mounted vertically or horizontally on a DIN rail. Up to 84 channels per meter can be mounted.
