D5096S-100
SIL3/2 5 A Relay with LFD & Universal Fault Mirror
Description
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 trip 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.Features
