Beckhoff KL2622 Relay Output Terminal

The Beckhoff KL2622 is a 2-channel relay output terminal designed for switching high-voltage loads such as AC mains devices or DC-powered actuators. Each channel features a single potential-free make contact, suitable for both ohmic and inductive loads up to 5 A.

Ideal for automation tasks requiring galvanically isolated switching, the KL2622 offers safe and reliable operation with 500 V electrical isolation between the K-bus and field side. This terminal does not use power contacts, and its compact design integrates easily into decentralized control systems.
