BECKHOFF KM1018-0000 Bus Terminal Module

Description

The BECKHOFF KM1018-0000 is a high-density Bus Terminal module designed to accommodate 64 digital inputs within a compact housing. Operating at a nominal voltage of 24 V DC, this module acts as a space-saving interface within the Beckhoff I/O system, transmitting electrically isolated signals directly to higher-level automation units via the K-bus. By integrating 64 channels into a single physical unit, it significantly reduces control cabinet space requirements while maintaining accurate signal acquisition.

As the base configuration variant (-0000), the BECKHOFF KM1018-0000 is delivered without pluggable front connector blocks. This design enables system engineers to choose the appropriate wiring technology for their installation, including 1-wire or 3-wire plug-in connector strips with or without diagnostic status LEDs. The physical assembly mounts directly to standard DIN rails and interlocks with adjacent terminals for structural and electrical stability.

Features

• High-density interface providing 64 digital input channels.
• Fast signal acquisition with a typical input filter limit of 0.2 ms.
• Electrical isolation of 500 V between the K-bus and the field potential.
• Flexible wiring configuration utilizing a pluggable connector level (connector blocks ordered separately).
• Direct installation on standard 35 mm DIN rails using a secure double slot and key locking system.
• Low current consumption from the K-bus to optimize system energy efficiency.

Applications

• High-density digital signal acquisition in space-constrained control cabinets.
• Industrial automation systems requiring fast response times for digital sensor inputs.
• Machine tool, packaging machinery, and manufacturing line control via Beckhoff K-bus networks.

Installation Guidelines

1. Verify overall system compatibility and ensure the power supply is completely de-energized before beginning installation.
2. Mount the BECKHOFF KM1018-0000 module onto a standard 35 mm DIN rail (EN 60715) by sliding it into position. Ensure the side-by-side connection to adjacent terminals is secured using the double slot and key locking structure.
3. Verify that the mechanical K-bus contacts engage properly with the neighboring module.
4. Insert the compatible pluggable connector blocks (ordered separately) into the front of the terminal module.
5. Perform field wiring using appropriate conductors (0.08 to 1.5 mm²), stripping the insulation back exactly 8 mm.
6. Apply field-side 24 V DC power and execute a system configuration scan using TwinCAT System Manager to configure the process image.
