KL1012 - Beckhoff Bus Terminal Digital Input

The Beckhoff KL1012 Bus Terminal Digital Input is a reliable module designed to handle two digital input channels using 4-wire connection technology. It operates at a 24 V DC nominal voltage, distinguishing between “0” signals from -3 to +5 V and “1” signals from 15 to 30 V, in compliance with EN 61131-2 type 1. Each channel supports a typical input current of 5 mA and features a 0.2 ms input filter that enhances stability by eliminating transient disturbances. With a K-bus current consumption of only 3 mA, the module offers high efficiency in distributed I/O systems, while its bit width of two inputs integrates seamlessly into the process image without additional configuration.

Designed for compact cabinet layouts, the KL1012 comes in a robust polycarbonate housing measuring 12 x 100 x 68 mm and weighing just 50 g. It installs securely on a 35 mm DIN rail and allows modular side-by-side assembly via Beckhoff’s double slot and key connection. Signal LEDs provide clear visual indication for each input channel, simplifying diagnostics during commissioning and servicing. Flexible spring-actuated terminals support solid, flexible, and ferrule wiring, offering connection cross-sections up to 2.5 mm². The unit meets international certifications including CE, UL, CCC, ATEX, IECEx, and DNV GL, while vibration, shock, and EMC compliance ensure reliable performance in demanding environments.

In industrial applications, the KL1012 Bus Terminal Digital Input is widely used for monitoring switches, push buttons, and proximity sensors in machine tools, process plants, and building automation. Its simple configuration makes it ideal for OEMs and panel builders, while maintenance teams benefit from the integrated diagnostic LEDs and robust spring terminals that reduce downtime. Training centers and universities also employ the KL1012 to teach students practical PLC interfacing and digital input handling. With its compact footprint, proven durability, and trusted certifications, the Beckhoff KL1012 is a reliable choice for industries in India and worldwide looking for dependable Bus Terminal Digital Input solutions.
