DC relay module X1-NIS-RLO/SS-02-S

solid-stateswitchingsafety

The X1-NIS-RLO/SS-02 solid-state relay module is suitable for switching safety related circuits, up to SIL 2 level, for high risk industries. It provides isolation between input coils and output contacts, making available a safety NO contact for Normally Energized (NE) 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. To ease maintenance operations, field devices can be disconnected through a two-position insertion/extraction mechanism. This product requires a dedicated Termination Board.SIL 2 / SC 3Installation in Zone 2 / Division 2Loop disconnection to ease maintenance operationsUp to 2 A functional / 6 A inrush currentCompatible with DCS/PLC pulse testingThree port isolation, Input/Output/SupplyStatus: ACTIVEChannels: 1Technical DataGeneralPower Dissipation0.5 W @ 24 Vdc System Supply, with 2 A load current, typical.System SupplyVoltage24 Vdc nom (18 to 30 Vdc).Current Consumption5 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 OutTypeNE load.Max ratings2 A 60 Vdc 120 W.Max inrush current6 A.Operate / release time30 / 30 ms, typical.IsolationTest VoltageSystem In/Field Out 2.5 kV; System Supply/Field Out 2.5 kV; System In/System Supply 500 V.Environmental conditionsOperating temperaturetemperature limits –40 to +70 °C.Storage temperaturetemperature limits –45 to +80 °C.MountingTypeOn custom Termination Board.Weightabout 50 g.DimensionsWidth 10 mm, Depth 80 mm, Height 120 mm.Certifications: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-02UK Declaration of Conformity of X1-NIS-RLO/SS-02Characteristics / Technical Specifications:Product type: SIL2 Solid-State Relay Out Module for 2A NE LoadsChannels: 1Power Dissipation: 0.5 W @ 24 Vdc System Supply, with 2 A load current, typicalSystem Supply Voltage: 24 Vdc nom (18 to 30 Vdc)System Supply Current Consumption: 5 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 Type: DC voltage supplyField Supply Voltage range: 0 to 60 VdcField Out Type: NE loadField Out Max ratings: 2 A 60 Vdc 120 WField Out Max inrush current: 6 AOperate / release time: 30 / 30 ms, typicalIsolation Test Voltage: System In/Field Out 2.5 kV; System Supply/Field Out 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
