New safety relays from Weidmuller

With its new SAFESERIES safety relays, Weidmüller offers modules designed to shut down process industry plant and plant components in the event of an emergency.

The G3 coated version is a requirement for applications, where there is a high concentration of hydrogen sulphide and it has been tested in accordance with EN 60068-2-60. TUV NORD has certified that the SAFESERIES safety relay range fulfils SIL3 requirements in accordance with EN 61508.

Part of range, the new SCS 24V DC SIL3 safety relay is designed to guarantee emergency shutdown of systems and system components operating in the process industry.

Safety shutdown is critical in the process industry because it serves functional safety, for instance in backup systems with high DC voltages. EN 61508 specifies that all devices used in safety circuits must fulfil particularly strict conditions. SIL (Safety Integrity Level) makes it possible to classify corresponding devices according to the reliability of their safety function and the safety oriented design principles that must be maintained in order to minimise the risk of malfunctions.
