Switching relay module D5095S

DCACsafety

5 A SIL 3 NC CONTACT RELAY OUT MODULE FOR NE OR F&G/ND LOAD DESCRIPTION The D5095S 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. D5095S 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 both NE load and F&G / ND load is available. Load can be isolated from supply on both polarities: +/AC, -/AC. Mounting on standard DIN-Rail or on customized Termination Boards, in Safe Area or in Zone 2. FEATURES • Systematic capability SIL 3 • Installation in Zone 2. • Compatible with DCS/PLC pulse testing. • 5 A high availability to avoid spurious trip SIL 3 contacts for NE or F&G/ND load. • 6 A inrush current at 24 Vdc / 250 Vac. • Input/Output isolation. • EMC Compatibility to EN61000-6-2, EN61000-6-4, EN61326-1, EN61326-3-1 for safety system. • Simplified installation using standard DIN-Rail and plug-in terminal blocks or customized Termination Boards.
