EL2784, EL2794 | 4-channel digital output terminals 30 V AC/DC, 2 A, solid state
The digital EL2784 and EL2794 EtherCAT Terminals provide four switches that can be used like a relay contact for AC/DC voltages. The electronic switch is realised through high-performance MOSFET transistors with low switch-on resistance. The switch itself is not short-circuit-proof, but due to its high pulse current capability it can cope with current until an external fuse triggers a switch-off. Wear resistance increases the availability of the application. Resistive and light inductive loads can be switched up to a rated voltage of 30 V AC/DC, compley resistive loads also up to a rated voltage of 48 V DC. High peak voltages and electromagnetic interference pulses are prevented.
