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)
