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.
