Description

10 A SIL 3 RELAY OUTPUT MODULE FOR NE LOAD DESCRIPTION The single channel Relay Output, D5290S 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 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: when enabled, it allows DCS/PLC to detect short circuit fault of module. D5290S provides two NO contacts for normally energized load and a NC 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 / Non Hazardous Location or in Zone 2 / Class I, Division 2 or Class I, Zone 2.
