BECKHOFF EL2901 Potential Supply Terminal

The EL2901 Safety EtherCAT Terminal is a potential power supply terminal and enables the setting up of TwinSAFE groups with safe power supply (24 V DC, up to 10 A). If the TwinSAFE Terminal detects a fault, it switches to safe state (fail safe). Safe potential groups can be created within a terminal strand using the EL2901. The EL2901 meets the requirements of IEC 61508 SIL 3 and DIN EN ISO 13849 PLe.
