Beckhoff ED2838 | EtherCAT Terminal, 8-channel digital output

The ED2838 digital output terminal connects the binary 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 light

emitting diodes (status LEDs).

An overload detected by the integrated diagnostics can be

evaluated in the controller and is also indicated by LEDs.

A diagnostic bit is set for the affected channel if there is an

overload. The diagnostics serve to simplify the maintenance

of the application.

The power contacts are looped through. In the ED2838 the

outputs are supplied via the 24 V DC power contact.

They are electrically isolated from the fieldbus side.

Special features:

• suitable for controlling different types of loads:

• resistive loads (e.g., resistors)

• inductive loads (e.g., relays, contactors, valves)

• capacitive loads

• max. output current of 2 A per channel (∑ 10 A)

• integrated diagnostic option: overload

• short-circuit proof outputs: protection against overload or

short circuit

• reverse polarity protection in the event of incorrect polarity

of the supply voltage

The ED series EtherCAT Terminals have push-in connection

technology which makes wiring easy and tool-free.
