Product Description:

The KM Bus Terminal series from Beckhoff presents the KM1012 as a compact, efficient digital input module intended for industrial automation systems.

The 16 digital input capabilities of this device are split into two groups of eight, which provides an excellent solution for compressed configurations in numerous signal handling applications. Plug connection technology in this module provides quick binding of wiring that also ensures secure and trouble-free operations and maintenance. The KM1012 follows EN 61131-2 type 1 standards to perform reliable signal processing in compliance with industry specifications. The inputs function using 24 V DC at nominal, but can vary between -15% to +20% of nominal, which produces steady operation through minor power fluctuations. The signal thresholds maintain clear definitions which ensure operation durability: any voltage between -3V to +5V signals a logical “0” and a range of 15V to 30V indicates a logical “1.” Every input runs at 5 mA before being protected by a quick input filter, which operates at 0.2 milliseconds for noise-free and precise signal acquisition.

Construction of this module integrates the Beckhoff K-bus interface as it operates on power consumption of approximately 3 mA, which results in energy-efficient operation. The device installation process becomes simpler because it operates without power contacts, which also reduces the wiring system complexity. Each of the 16 inputs within the process image needs 16 bits to construct a seamless integration with PLC and control software. This small-sized control unit offers dimensions of 26.5 mm x 100 mm x 71 mm (H x W x D) that enable its placement in constrained control cabinets. The device functions within temperatures between 0°C and 55°C, and its storage requirements span from -25°C to +85°C.
