Beckhoff KL2889 Digital Output Terminal

The Beckhoff KL2889 is a 16-channel digital output Bus Terminal designed for transmitting binary control signals from automation devices to field-level actuators with full electrical isolation. Built in a compact 12 mm HD housing, it enables space-efficient wiring while offering robust output performance.

The KL2889 features short-circuit and overload protection on each channel, as well as reverse polarity protection. With direct plug-in wiring for solid conductors and clear LED indicators for each output, this terminal is ideal for compact control cabinets requiring high-density signal distribution using ground-switching logic.
