The EL2819 digital output terminal connects the binary 24 V DC control signals from the automation device on to the actuators at the process level with electrical isolation. The EtherCAT Terminal has 16 channels, whose signal states are indicated by LEDs. The integrated diagnostics can be evaluated in the controller and is indicated by the LEDs. Maintenance of the application is simplified by the diagnostics. The power contacts are connected through. The reference ground for the outputs is the 0 V DC power contact. The outputs are electrically isolated from the fieldbus side.
