The Beckhoff KL1408 is an 8-channel digital input Bus Terminal for 24 V DC signals with 1-wire connection, engineered for high-density signal acquisition in modular PLC and machine control applications. As part of the KL series, it fits seamlessly into Beckhoff K-bus I/O architectures, helping panel builders and OEMs scale digital input capacity in a compact 12 mm footprint.

Each of the eight channels complies with EN 61131-2 (type 1/3) and benefits from a typical 3 ms input filter for reliable debouncing and noise suppression. The terminal operates at 24 V DC with a tolerance of -15%/+20%, provides 500 V isolation between K-bus and field level, and maps all inputs directly into the process image without address or configuration settings. An IP20 compact housing with status LEDs and spring-actuated wiring streamlines cabinet integration on a 35 mm DIN rail.

Built for robust industrial environments and supported by CE, UL, ATEX and IECEx approvals as well as DNV for marine use, the KL1408 delivers dependable digital input performance across a wide range of control systems, helping you standardize Beckhoff Bus Terminal installations with the added assurance of a 1-year warranty.
