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 a1.5 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.
