Beckhoff KL3204 is a four-channel resistance-temperature and resistance-measurement Bus Terminal used in industrial automation, machine maintenance, exact-part replacement, and installed-base support.
The Beckhoff KL3204 connects resistance temperature detectors and other resistive sensors directly to a Beckhoff K-bus I/O station. Four channels are combined into one compact terminal, and the onboard electronics perform sensor excitation, measurement, and linearization before passing the resulting values through the K-bus. Although Pt100 temperature measurement is one of its most common uses, the terminal also supports several other Pt and Ni sensor types as well as resistance measurement for devices such as potentiometers.
This page is built around the exact manufacturer reference KL3204. Industrial components that look similar can differ in firmware, voltage, signal type, I/O architecture, connector style, communications, safety functions, or machine-specific configuration. Using the exact part number helps reduce engineering changes, troubleshooting, and production downtime.
Lifecycle / sourcing status
Regular delivery, but part of Beckhoff's mature K-bus Bus Terminal platform with a substantial installed base.
Key product details
Common applications
Temperature monitoring on machines, ovens, process systems, test equipment, thermal systems, production equipment, OEM machinery, and maintenance of mature Beckhoff K-bus installations.
Compatibility and ordering note: Confirm KL3204 model, sensor type, resistance range, 2-wire wiring arrangement, terminal revision, K-bus coupler/controller, process-data format, calibration requirements, and PLC configuration before replacement.
Why this part is commonly sourced: KL-series temperature terminals are often sourced as exact spares because converting a mature K-bus station to newer I/O can require hardware, wiring, PLC-mapping, and software changes that are unnecessary when the exact terminal is still obtainable.
