Beckhoff ED2807 | EtherCAT Terminal, 32-channel digital output, 24 V DC, 0.5 A, push-in

The ED2807 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 32 channels that indicate their signal state via light emitting

diodes (status LEDs). The power contacts are looped through

internally. In the ED2807 the outputs are supplied via the 24 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 ground reference

as the ED2807.

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 (∑ 10 A)

• positive 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 ED series EtherCAT Terminals have push-in connection technology

which makes wiring easy and tool-free.

The digital EL2788 EtherCAT Terminal provides eight switches

that can be used like a relay contact for AC/DC voltages.

The electronic switch is realized through high-performance

MOSFET transistors with low on-resistance.

The switch itself is not short circuit proof, but thanks to its

high pulse current capability it can cope with current until

an external fuse is triggered. The wear resistance increases

the availability of the application. Ohmic and slightly inductive

loads can be switched up to a rated voltage of 30 V AC/DC.

Purely ohmic loads can be switched up to 48 V DC rated

voltage. High peak voltages and electromagnetic interference

pulses are prevented. The power contacts are linked.

The outputs of the EL2788 are supplied via the power contacts.

The EL2535-xxxx output terminals are specially designed for the precise

control of single and double-coil proportional valves and proportional

solenoid valves. They regulate the output current through pulse width

modulation (PWM) of the supply voltage and are electrically isolated

from the E-bus. The current values (0 to maximum output current)

are specified by the automation device through a 16-bit value. 

The output stages are protected against overload and short circuit.

Each EtherCAT pulse width current terminal contains two channels

whose signal state is indicated by LEDs. The light emitting diodes

simplify local diagnosis by displaying typical load and wiring faults.

A practical test was able to show that an EL2622-0010 remained

fully functional at a capacitive continuous current load of 4 A after

200.000 switching cycles  (for details see documentation).

The signal state of the EtherCAT Terminal is indicated by light

emitting diodes.The EL2595 EtherCAT Terminal contains a

constant current source for LEDs and is designed to control one

or more LEDs connected in series.
