EL2902 | 2-channel digital output terminal, TwinSAFE, 24 V DC, 2.3 A

The EL2902 safety EtherCAT Terminal is a digital output terminal with two channels. It switches 24 V DC actuators with up to 2.3 A current per channel. If the EtherCAT Terminal detects a fault, it switches off automatically (fail stop). The EL2902 meets the requirements of IEC 61508 SIL 3 and DIN EN ISO 13849 PL e.
