SIL3 Electro-Magnetic Relay Out Module for 2A ND/F&G Loads with DiagnosticsThe X1-NIS-RLO/EM-05 electro-magnetic relay module is suitable for switching safety related circuits, up to SIL 3 level, for high risk industries. It provides isolation between input coils and output contacts, making available a safety NO contact for Normally De-energized (ND) or Fire & Gas (F&G) loads. A wide compatibility towards different DCS/PLC is guaranteed: driving pulse testing is permitted by a dedicated internal circuit, which prevents contact and LED flickering, while offering an acceptable resistance to the DO Card. Line and load short/open circuit detection with programmable limits and load voltage monitoring are provided, both when the load is off and when the load is on. The fault in the field is directly mirrored to the PLC DO by artificially increasing the input impedance without commuting the relay contacts, and it is also reported to the cumulative fault. To ease maintenance operations, field devices can be disconnected through a two-position insertion/extraction mechanism. This product requires a dedicated Termination Board.SIL 3 / SC 3Installation in Zone 2 / Division 2Loop disconnection to ease maintenance operationsUp to 2 A functional / 6 A inrush currentCompatible with DCS/PLC pulse testingLine & Load short/open circuit detection (programmable thresholds)Load voltage monitoringField fault mirroring to the DCS/PLC DO CardThree port isolation, Input/Output/SupplyStatus: ACTIVEChannels: 1GeneralPower Dissipation0.7 W @ 24 Vdc System Supply, with 2 A load current, typical.System SupplyVoltage24 Vdc nom (18 to 30 Vdc).Current Consumption10 mA @ 24 Vdc and relay energized, typical.System InType24 Vdc nom (21.5 to 30 Vdc).Current Consumption15 mA @ 24 Vdc, typical.Input impedance1.6 kΩ @ 24 Vdc, typical.Field SupplyTypeAC or DC voltage supply.Voltage range0 to 250 Vac, 0 to 110 Vdc.Field OutTypeND/F&G load.Max ratings2 A 250 Vac 500 VA, 2 A 110 Vdc 100 W (resistive load).Max inrush current6 A.Operate / release time≤ 30 / 30 ms.FaultTypeLoad & line short/open circuit, supply voltage monitoring.Line/load faultprogrammable resistance (20 Ω to 20 kΩ) and current (20 mA to 2 A) limits.Load supply voltage ok≥ 20 Vdc.Load supply voltage fault≤ 5 Vdc.Fault signallingcommon fault & fault mirroring on DCS/PLC DO.Response time≤ 1 s.Output typical characteristicsIsolationTest VoltageField Out/System In 2.5 kV; Field Out/System Supply 2.5 kV; System In/System Supply 500 V.Environmental conditionsOperating temperaturetemperature limits –40 to +60 °C.Storage temperaturetemperature limits –45 to +80 °C.MountingTypeOn custom Termination Board.
