SIL3 Solid-State Relay Out Module for 2A ND/F&G Loads with DiagnosticsThe X1-NIS-RLO/SS-05 solid-state 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 CardAutomatic TProof test available through GatewayThree port isolation, Input/Output/SupplyGeneralPower Dissipation0.9 W @ 24 Vdc System Supply, with 2 A load current, typical.System SupplyVoltage24 Vdc nom (18 to 30 Vdc).Current Consumption21 mA @ 24 Vdc and relay energized, typical.System InType24 Vdc nom (18 to 30 Vdc).Current Consumption12 mA @ 24 Vdc, typical.Input impedance2 kΩ @ 24 Vdc, typical.Field SupplyTypeDC voltage supply.Voltage range0 to 60 Vdc.Field OutTypeND/F&G load.Max ratings2 A 60 Vdc 120 W.Max inrush current6 A.Operate / release time30 / 30 ms, typical.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.IsolationTest VoltageField Out/System In 2.5 kV; Field Out/System Supply 2.5 kV; System In/System Supply 500 V.Environmental conditionsOperating temperature–40 to +70 °C.Storage temperature–45 to +80 °C.MountingTypeOn custom Termination Board.Weightabout 50 g.DimensionsWidth 10 mm, Depth 80 mm, Height 120 mm.Status: ACTIVEChannels: 1Certifications:ATEX: FM ATEX zone 2 X1 Series English Certificate (Europe) FM23ATEX0039X, FM, 2025-08-13Ex: FM US X1 Series Divisions and Zones English Certificate (North America) FM23US0073X, FM, 2025-08-12Ex: FM Canada X1 Series Divisions and Zones English Certificate (North America) FM23CA0055X, FM, 2025-08-12IECEx: FM IECEx X1 Series English Certificate (International) IECEx FMG 23.0018X, FM, 2025-08-12SIL: TUV IT 25 SIL 0531 A SIL Certificate Summary (International) TUV IT 25 SIL 0531 A Rev.1, TUV_SUD, 2025-09-19UKEx: FM UKEx zone 2 X1 Series English Certificate (United Kingdom) FM23UKEX0040X, FM, 2025-08-14Declarations of Conformity:EU Declaration of Conformity of X1-NIS-RLO/SS-05UK Declaration of Conformity of X1-NIS-RLO/SS-05Drawings:3D_drawing_X1-Cartridge_stpDimensions:Width: 10 mmDepth: 80 mmHeight: 120 mmConnections:See diagrams in images section.Technical Specifications Summary:Power Dissipation: 0.9 W @ 24 Vdc System Supply, with 2 A load current, typical.System Supply Voltage: 24 Vdc nom (18 to 30 Vdc)System Supply Current Consumption: 21 mA @ 24 Vdc and relay energized, typicalSystem In Type: 24 Vdc nom (18 to 30 Vdc)System In Current Consumption: 12 mA @ 24 Vdc, typicalInput impedance: 2 kΩ @ 24 Vdc, typicalField Supply Voltage range: 0 to 60 VdcField Out Max ratings: 2 A 60 Vdc 120 WMax inrush current: 6 AOperate / release time: 30 / 30 ms, typicalFault detection: programmable resistance (20 Ω to 20 kΩ) and current (20 mA to 2 A) limitsLoad supply voltage ok: ≥ 20 VdcLoad supply voltage fault: ≤ 5 VdcFault signalling: common fault & fault mirroring on DCS/PLC DOResponse time: ≤ 1 sIsolation Test Voltage: Field Out/System In 2.5 kV; Field Out/System Supply 2.5 kV; System In/System Supply 500 VOperating temperature: –40 to +70 °CStorage temperature: –45 to +80 °CMounting: On custom Termination BoardWeight: about 50 gDimensions: Width 10 mm, Depth 80 mm, Height 120 mm
