Beckhoff EL2904 TwinSAFE Digital Output EtherCAT Terminal

Beckhoff EL2904 TwinSAFE EtherCAT Terminal is a four-channel digital output module designed for safety-critical actuator control in EtherCAT networks. It provides four safe 24 V DC outputs for driving actuators such as contactors or relays, with a maximum current of 0.5 A per channel, all managed within the TwinSAFE safety over EtherCAT framework. Electrical characteristics include nominal 24 V DC supply with -15%/+20% tolerance, E-bus current consumption typ. 221 mA, and a weight of roughly 90 g; fault response time is ≤ watchdog time (parameterisable). Operating temperature range is -25 to +55 °C, and the device carries safety-related approvals (CE, UL, Ex, TÜV SÜD) appropriate for use in control panels requiring Cat 4/PL e and SIL 3 compliance.
