To provide distributed safety I/O technology in more form factors and protection levels, the EP1908 EtherCAT Box with TwinSAFE technology has been expanded to include a flexible, IP 67-rated variant for use outside of electrical cabinets and in harsh environments.

The EtherCAT Box has eight 24 Vdc safety inputs, which can be used to connect safety sensors using M12 connectors. The box withstands demanding industrial environments while conforming to the requirements of IEC 61508 SIL 3 and DIN EN ISO 13849-1 PLe. It enables the acquisition of safety sensor signals directly on the machine instead of having to mount the safety I/O inside a control cabinet.  Inputs can accept OSSD signals from light curtains and laser scanners.  Zero speed monitoring through an encoder or proximity switch in the range of 0 – 500 Hz max is also possible.
