Product Description:

The KM1008-0002 is a digital input bus terminal produced by Beckhoff as a member of the KM Bus Terminals series. In decentralized control systems, it collects sensor contacts and transports their states across the internal K-bus to a higher-level PLC. The module’s housing mates electrically and mechanically with adjacent I/O slices, allowing channel counts to be scaled per cabinet section without rewiring field devices. As part of Beckhoff’s modular platform, the terminal serves packaging lines, material handling stations, and general machine controls that rely on compact, rack-mounted signal acquisition.

Internally, the terminal distributes field potential through a nominal supply of 24 V DC that feeds its optically isolated input sections. Each module presents 64 (8 x 8) digital input channels to the process image, allowing a controller to sample a large number of signals in one slice. A hardware debounce stage establishes a fixed input filter of 3.0 ms, so short transients are suppressed before they reach application software. Control electronics consume only 5 mA from the K-bus, minimizing current loading on the backplane. Mechanical integration is completed by snapping the housing onto a 35 mm DIN rail, which aligns the signal connectors with adjacent Beckhoff terminals.

The housing carries a protection rating of IP20, which helps prevent fingers from reaching live parts and suits the device for ventilated control cabinets. Overall dimensions of 123 x 100 x 55 mm determine the panel footprint and the clearance needed for upward plug removal. Signal circuits meet the input requirements of EN 61131-2 Type 1, providing defined threshold levels for common PNP sensor outputs. Field wiring follows the single-conductor 1-Wire method with an 8 mm stripping length, so individual leads can be terminated without ferrules while remaining compatible with the insulation displacement contacts molded into the pluggable connectors.
