Beckhoff KL9210 Power Feed Terminal

The Beckhoff KL9210 is a diagnostic-enabled power feed terminal designed to establish and monitor 24 V DC potential groups in modular automation systems. Equipped with an integrated 6.3 A fine-wire fuse, the KL9210 not only distributes power to the field but also allows real-time monitoring of the supply voltage via two input bits reported to the Bus Coupler.

It features green and red LEDs for status and fault indication, 500 V electrical isolation, and supports seamless integration alongside terminals with or without power contacts. Ideal for building intelligent and fault-tolerant control architectures.
