Switching relay module D5097S

ACsafetytrip

5 A SIL 3 NC CONTACT RELAY OUT MODULE FOR NE OR F&G/ND LOAD WITH OPEN/SHORT CIRCUIT DIAGNOSTIC DESCRIPTION The D5097S 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. A wide compatibility towards different DCS/PLC is guaranteed: driving line pulse testing, executed by DCS/PLC, is permitted by a dedicated internal circuit, to prevent relay and LED flickering. D5097S has 2+2 SPST relay contacts connected in parallel and then in series to avoid spurious trip and to increase availability (see function diagram). High availability SIL 3 Safety Function for NE load or F&G / ND load is available. Load is isolated from supply on both polarities: +/AC, -/AC. Mounting on standard DIN-Rail, with or without Power Bus, or on customized Termination Boards, in Safe Area or in Zone 2.
