D5290S-078
5 A SIL 3 Relay Output Module for NE or ND Loads with NE or ND Relay condition
Description
The D5290S-078 is a relay module suitable for the switching of safety related circuits, up to SIL 3 level according to IEC 61508 for high risk industries. It provides isolation between input channel and output contacts.Three mutually exclusive (by DIP-Switch programming) monitoring circuits are provided:
1) line input monitoring, to allow DCS/PLC line monitoring function: when enabled, the module permits a wide compatibility towards different DCS/PLC. Driving line pulse testing, executed by DCS/PLC, is permitted by a dedicated internal circuit, to prevent relay and LED flickering.
2) low voltage input monitoring: when enabled, the module reflects a high impedance state to the control unit when the driving voltage is below the specified threshold.
3) short circuit fault detection (only for Functional Safety applications with NE Relay condition): when enabled, it allows DCS/PLC to detect short circuit fault of module.
Mounting on standard DIN-Rail or on customized Termination Boards,in Safe Area / Non Hazardous Location or in Zone 2 / Class I, Division 2 or Class I, Zone 2.
