Switching relay module D5096S-100

safetyDIN rail mountedisolated

The D5096S-100 is a relay module suitable for switching safety-related circuits up to SIL 3 level for high-risk industries. It provides isolation between input and output contacts. It makes available 2+2 NO relay contacts connected in parallel and then in series to avoid spurious trips and to increase process availability. High process availability SIL 3 Safety Function for Normally Energized (NE) and SIL 2 for Normally De-energized (ND) / F&G loads is available. Load can be isolated from supply on both polarities. 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. Line and load short/open circuit detection 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 opening the input and it is also reported by opening the fault output. The fault mirroring technique guarantees a wide compatibility to PLC DO cards. - SIL 3 / SC 3 for NE loads with NE driver - SIL 2 / SC 3 for ND loads with ND driver - Installation in Zone 2 - Up to 5 A functional / 6 A inrush current - Load disconnection on both supply lines available - High process availability to avoid spurious trips - Compatible with DCS/PLC pulse testing - Line & Load short/open circuit detection - Load voltage monitoring - Universal field fault mirroring to the PLC DO - Service contact available - Input/Output/Supply isolation Technical Specifications: - Supply: 24 Vdc nom (18 to 30 Vdc), reverse polarity protected.
