Function :

This isolated barrier is used for intrinsic safety applications. The device transfers digital signals (SN/S1N proximity sensors or approved dry contacts) from a hazardous area to a safe area. 

The input controls one output with 3 form A normally open relay contacts (one is in series to the 2 output relay contacts for the safety function), 

one output with 1 form A normally open relay contact, and one passive transistor output.

Unlike an SN/S1N series NAMUR proximity sensor, a mechanical contact, requires a 10 kilohm resistor to be placed across the contact in addition to a 1.5 resistor in series. 

Lead breakage (LB) and short circuit (SC) conditions of the control circuit are continuously monitored. 

During an error condition, fault output energizes and outputs I and II de-energize.

For safety applications up to SIL3, output I must be used.
