5 A SIL 3 Relay Output Module for NE Load


The single channel Relay Output D5090S-086 is a relay module suitable for the switching of safety related circuits, up to SIL 3 level according to IEC 61508:2010 Ed.2 for high risk industries. It provides isolation between input 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: when enabled, it allows DCS/PLC to detect short circuit fault of module.

D5090S-086 provides two NC contacts for normally energized load and a NO contact for service purpose, in order to switch the NE load on both supply lines.

Mounting on standard DIN-Rail or on customized Termination Boards, in Safe Area or in Zone 2.


• Systematic capability SIL 3
