The EL2008 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. Each EtherCAT Terminal has eight channels that indicate their signal state via light emitting diodes.

Special features:

• Connection of different load types possible (ohmic, inductive, lamp load)
• Max. output current 0.5 A per channel
• Short-circuit-proof outputs and reverse polarity protection
