Beckhoff KL1104 is a four-channel 24 VDC digital input Bus Terminal used in industrial automation, machine maintenance, exact-part replacement, and installed-base support.
The Beckhoff KL1104 acquires four binary 24 VDC field signals and transfers them through the Beckhoff K-bus to the higher-level controller. Each channel includes local LED indication, and Beckhoff specifies a typical 3 ms input filter that helps suppress contact bounce from mechanical switches. The terminal also provides 24 VDC and 0 VDC sensor-supply connections for convenient 2- or 3-wire device wiring. The KL1104 is widely found in mature Beckhoff I/O stations where compact distributed digital input is required.
This page is built around the exact manufacturer reference KL1104. 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 large installed base.
Key product details
Common applications
Limit switches, proximity sensors, pushbuttons, machine interlocks, conveyor controls, packaging equipment, OEM machinery, and mature Beckhoff K-bus I/O stations.
Compatibility and ordering note: Verify KL1104 model, input voltage, 2-/3-wire device arrangement, K-bus coupler/controller, terminal revision, process-image mapping, sensor power requirements, and PLC configuration before replacement.
Why this part is commonly sourced: Mature K-bus installations often need exact terminals to avoid replacing an entire I/O station. The KL1104 remains a practical spare where original wiring and process mapping should be retained.
