Beckhoff EL2794 | EtherCAT Terminal, 4-channel solid state relay output

The digital EL2794 EtherCAT Terminal provides four 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 EL2794 features potential-free contacts; the power

contacts are passed through.

Special features:

• 4 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 2 A per channel

• potential-free
