Beckhoff KL3054 Bus Terminal

The Beckhoff KL3054 is a 4-channel analog input terminal designed to transmit analog current signals in the 4…20 mA range with high accuracy and electrical isolation to automation systems. With 12-bit resolution, built-in diagnostics for wire break and overload, and single-ended configuration, it is ideal for precise current signal acquisition from sensors and transmitters.

The KL3054 supports 2-wire sensors and offers fast conversion time, robust surge protection, and simplified wiring in space-saving terminal housing.
