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 active voltage output and one relay contact output with a NO contact. 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 and the 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.
