Beckhoff ED2889 | EtherCAT Terminal, 16-channel digital output

The ED2889 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 16 channels that indicate their signal state

via light emitting diodes (status LEDs). The power contacts are looped

through internally. In the ED2889 the outputs are supplied via the 0 V

DC power contact. 

The connection technology is optimized for single-ended signals (common

reference point). To ensure error-free operation, all connected components

must use the same reference as the ED2889 terminal.

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 0.5 A per channel

• ground switching

• short-circuit proof outputs: protection against overload or short circuit

• reverse polarity protection in the event of incorrect polarity of the supply voltage

The EL2872 digital output terminal offers a very compact design

with its 16 channels. A 20-pin contact strip enables the secure

connection of plug connectors using insulation displacement

contact, as is usual for ribbon cables and special round cables.

This significantly simplifies the wiring of many channels.

The signal states of the channels are indicated by LEDs.

The EL2838 digital output terminal connects the binary control signals

of the automation device to the actuators at process level with electrical

isolation. The EtherCAT Terminal contains eight channels, which indicate

their signal status by means of LEDs.

The integrated diagnostics can be evaluated in the controller and are

indicated by the 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.

The outputs of the EL2838 are supplied via the 24 V power contact.

The outputs are electrically isolated from the fieldbus side.

Special features:

• connection of different load types possible (resistive, inductive,

lamp load).

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

• short-circuit proof outputs and reverse polarity protection

• integrated diagnostic option overload

• tool-free connection due to direct plug-in technology for solid 

conductors.
