The EL2032 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 two channels that indicate their signal state via light emitting diodes. The integrated diagnostics can be evaluated in the controller and is indicated by the LEDs. The EL2032 allows direct connection of two 3-wire actuators.

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
• Integrated diagnostics capability
• Short-circuit detection per channel
• Line break detection per channel
