Beckhoff KL3051 Bus Terminal

The Beckhoff KL3051 is a 1-channel analog input terminal for precise measurement of 4…20 mA current signals with 12-bit resolution and full electrical isolation. It supplies power to field transducers via the power contacts while delivering accurate, isolated signal acquisition for automation systems. This terminal is ideal for interfacing sensors in distributed I/O environments, providing real-time diagnostics for wire break and overload conditions via integrated LED indicators.

Its compact design and compatibility with 2-wire transmitters make the KL3051 a versatile choice for industrial control panels and process monitoring.
