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 relay contact output with 3 NO contacts

(one output is in series to the both output relays for the safety

function), one relay contact output with one NO contact, and

one passive transistor output.

Unlike an SN/S1N series proximity sensor, a mechanical

contact, requires a 10 kΩ resistor to be placed across the

contact in addition to a 1.5 kΩ resistor in series.

Lead breakage (LB) and short circuit (SC) conditions of the

control circuit are continuously monitored.

During an fault condition, the fault indication output energizes

and outputs I and II de-energize.

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

safety applications up to SIL2, output I and output II can be

used.
