Beckhoff KL2761 Bus Terminal

The KL2761 is a single-channel relay output terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system, featuring integrated diagnostics. It uses an electromechanical relay to switch loads that require galvanic isolation or that operate at voltages beyond the standard 24 V DC range, such as 230 V AC actuators, lamps, contactors, and valves, while providing diagnostic feedback on relay status. It belongs to the same relay output family as the KL2602, KL2612, KL2622, KL2631, KL2641, KL2652, and KL2692. 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.
