The EL2828 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 eight channels whose signal state is indicated by LEDs. The power contacts are connected through. In the EL2828 the outputs are supplied via the 24 V DC power contact.

Special features:

• Connection of different load types possible (ohmic, inductive, capacitive)
• Max. output current of 2 A per channel (∑ 10 A)
• Overload and short-circuit proof outputs and reverse polarity protection
• Tool-free connection by direct plug-in technology for solid wire conductors
