Beckhoff KL2794 original output

The KL2794 is a four-channel solid-state relay (SSR) output terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system. Unlike electromechanical relay terminals, it uses semiconductor output stages to switch 230 V AC loads without moving contacts, providing long life, fast switching, and no contact wear. It belongs to the same AC solid-state output family as the KL2701, KL2702, KL2712, KL2722, and KL2732, with a higher channel count. Unlike EtherCAT terminals (EL series), the KL series communicates via the K-Bus and is typically used with Beckhoff Bus Couplers or Bus Terminal Controllers.
