EL2124 | 4-channel digital output terminal 5 V DC

The EL2124 digital output terminal connects the binary control signals from the automation unit on to the actuators at the process level with electrical isolation. The load current outputs of the EL2124 are protected against overload and short circuit. The EtherCAT Terminal has four channels that indicate their signal state via light emitting diodes.
