DC relay module X1-NIS-RLO/EM-03-S

ACswitchingsafety

The X1-NIS-RLO/EM-03 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. 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 testingThree port isolation, Input/Output/SupplyTechnical Specifications:Power Dissipation: 0.4 W @ 24 Vdc System In, with 2 A load current, typical.System In: Voltage: 24 Vdc nom (21.5 to 30 Vdc).
