D5295S
5 A SIL 3 NC contact Relay Out Module for NE or F&G/ND Load with open/short circuit diagnostic
Description
The single channel 4 A Relay Output, D5295S 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.
D5295S has 2+2 relay contacts connected in parallel and then in series to avoid spurious trips and to increase availability.
Features
