DC relay module D5293S

ACprogrammableswitching

The D5293S 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 two NO contacts for Normally Energized (NE) loads, in order to disconnect the load on both supply lines, and a NC contact for service purpose. 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 and it is also reported by opening the fault output. Diagnostic parameters are programmable and can also be monitored/configured through Modbus.SIL 3 / SC 3 for NE loads with NE driverSIL 2 / SC 3 for FAULT OUTPUTSInstallation in Zone 2/Div. 2Up to 5 A functional / 6 A inrush currentLoad disconnection on both supply lines availableCompatible with DCS/PLC pulse testingLine & Load short/open circuit detectionLoad voltage monitoringField fault mirroring to the PLC DOModbus RTU RS-485 for monitor & configurationService contact availableInput/Output/Supply isolationTechnical Specifications:Supply: 24 Vdc nom (18 to 30 Vdc), reverse polarity protected.
