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.

Special features:

• 8 x make contacts as substitutes for relay contacts

• switching of ohmic loads up to a rated voltage of 30 V

AC/48 V DC

• switching of slightly inductive loads up to a rated voltage

of 30 V AC/DC

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

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

prevented. The power contacts are linked. The outputs of the

EL2784 are supplied via the power contacts.

Special features:

• 4 x make contacts as substitutes for relay contacts

The ELX2792 output terminal has two relays, each with a

changeover contact, which can be used universally to

switch intrinsically safe loads up to zone 0/20. 

These could be, for example, solenoid valves, contactors

or optical/acoustic signal devices. The ELX2792 features

potential-free contacts. The signal state of each individual

channel is displayed by an LED. EtherCAT Terminals from 

the ELX series must always be operated in conjunction

with the ELX9560 power feed terminal, which generates

an electrically isolated output voltage (24 V EX) from the

input voltage (24 V DC) to supply the downstream ELX

terminals. If a renewed feed-in should be necessary,

the combination of an ELX9410 and an ELX9560 can be

used so that further ELX terminals can be connected inline.

The ELX terminal segment must be terminated with one

ELX9012. two ELX9410 or one EK1110.

The use of two ELX9410 allows the use of EL terminals

behind ELX terminals. With the EK1110. the terminal

segment can be continued via an EtherCAT cable,

for example to implement cable redundancy.

With the switching terminals of the EL/ELM264x (reed) and

ELM274x (solid-state) series, Beckhoff significantly expands

the application possibilities of the integrated measurement

technology of the ELM3xxx series, as well as normal EL3xxx

/EL4xxx analog inputs and outputs.

This is because several sensors or sources can now be

connected to one analog input channel at the same time

via high-quality, EtherCAT-controlled switches.

For this purpose, the EL2642 is equipped with reed relays as

switching elements that allow fast switching cycles with a long

service life. The electrical isolation and the constant transition

resistance of the reed switch allow the measurement of sensitive

signals up to fast scanning operation. Due to the double input

connections X, the channels can simply be connected to 1 x 8

multiplexers andm more. The multi-channel acquisition of analog

signals as well as the flexible switching of various test states in

production integrated test stations is thus simple to do through

the integration of the switches into the EtherCAT system.

The EL2596-0030 LED strobe control terminal contains a flexible power supply

unit that supplies the LED with the required current and voltage.

Applications from continuous light to short light pulses in the kHz range are thus

possible. Each individual flash can be triggered in a controlled manner by the

control system via the distributed clocks/timestamp function.

The EL2596-0030 has a trigger output for triggering cameras and high-quality,

fast current and voltage control, so that line scan cameras, for example,

also benefit from constant illumination. Extensive real-time diagnostics, e.g.

for input current/voltage and output current/voltage allow detailed monitoring

of the LED light intensity. Thus, overdrive applications with short high-current

pulses through the LEDare possible. If a specifiable load corridor is exited, e.g.,

due to load errors, the EL2596-0030 switches off to protect the LED (resettable).

Special features:

• suitable for lighting-related vision applications up to 24 V DC

• max. output current 0…3 A in pulse mode / 0…1.2 A in continuous mode

• different operating modes possible

• continuous mode (current and voltage output, PWM)

• pulse operation

• RGB/common anode mode

• support of XFC technology timestamp

• synchronized operation through distributed clocks XFC technology possible

• The EL2564 is the right choice for lighting tasks with RGBW LEDs in voltage mode.

• The EL2595 LED terminal of the 1st generation can be used for current-regulated

control of LEDs.
