Beckhoff Automation has introduced the new EP1908 EtherCAT Box with TwinSAFE technology. With the EP1908, the open safety technology of TwinSAFE has been expanded to include a flexible, IP 67-rated variant that is recommended for use outside of electrical cabinets and in harsh environments. Certified for use throughout North America, the EP1908 EtherCAT Box has eight 24V DC safety inputs, which can be used to connect safety sensors via rugged and reliable M12 connectors. The EP1908 is designed to withstand demanding industrial environments while conforming to the requirements of IEC 61508 SIL 3 and DIN EN ISO 13849-1 PLe. Also, 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 via encoder or proximity switch in the range of 0 – 500 Hz max is also possible.
