Switch Amplifier
Opis
This isolated barrier is used for intrinsic safety applications. 1-channel isolated barrier, 115/230 V AC supply, Input for approved dry contacts or SN/S1N sensors, Relay contact output, Fault indication output, Line fault detection (LFD), Up to SIL 3 acc. to IEC 61508, Up to PL d acc. to EN/ISO 13849pa. The device transfers digital signals (SN/S1N proximity sensors or approved dry contacts) from a hazardous area to a safe area. The input controls 1 relay contact output with 3 NO contacts (1 output is in series to the both output relays for the safety function), 1 relay contact output with 1 NO contact, and 1 passive transistor output (fault indication 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 SIL 3, output I must be used. For safety applications up to SIL 2, output I and output II can be used.
