The EL2024 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 contains four channels whose signal state is indicated by LEDs. Direct connection of four 2-wire actuators is possible because the terminal has four ground connection points.

Special features:

• Connection of different load types possible (ohmic, inductive, lamp load)
• Max. output current 2 A per channel
• Short-circuit-proof outputs and reverse polarity protection
