Beckhoff KM1004-0000 Module d'entrée numérique 32 canaux

Product Overview

The KM1004-0000 (KM1004-0000) is a high-density Bus Terminal module featuring 32 digital inputs designed for advanced industrial automation systems. This module provides a compact solution for collecting up to 32 discrete 24 V DC signals, transmitting them to the central automation unit via electrical isolation. The KM1004 series is engineered for integration within the standard Beckhoff I/O system, offering a pluggable wiring level that significantly streamlines installation and maintenance in space-constrained control cabinets. It is an ideal choice for large-scale sensor monitoring where high channel density is required to minimize the overall footprint of the I/O assembly.

Technical Configuration

The KM1004-0000 architecture is optimized for 32-channel signal processing, organized into four groups of eight inputs per connector. It operates on a 24 V DC nominal voltage and adheres to the EN 61131-2 Type 1 specification. The module features a 3.0 ms input filter to suppress signal noise and ensure reliable data capture. Designed for versatility, the KM1004-0000 does not utilize power contacts, drawing its logic power from the K-bus. It is physically designed for mounting on standard 35 mm DIN rails and supports side-by-side assembly using a double slot and key connection, allowing for scalable and organized control panel configurations.

Technical Specifications

FAQs

What is the difference between the KM1004-0000 and the -0001, -0002, or -0004 variants?

The -0000 is the base module supplied without connectors. The other variants (-0001, -0002, -0004) include specific connector types (1-wire or 3-wire) and LED status indicators to suit different wiring and diagnostic requirements.

Are these modules compatible with standard EtherCAT terminals?

The KM series are Bus Terminal modules integrated into the I/O system. Ensure your controller architecture is configured for the specific Bus Terminal system compatibility required by these modules.

Does this module require any address or configuration settings?

No. The KM1004-0000 is a "plug-and-play" module; it does not require manual addressing or configuration settings, as it is automatically recognized and managed by the higher-level automation unit.

Can this module be used in environments with high electrical noise?

The inputs are electrically isolated by 500 V between the K-bus and the field potential, which helps protect the internal electronics from common-mode noise and transients found in heavy industrial environments.

Installation Guidelines and Best Practices

• Wiring Connectors: The KM1004-0000 requires the use of compatible female headers (such as the ZS2001 series) to establish the plug-in connection level. Choose the header based on your wiring scheme (1-wire or 3-wire) and whether LED diagnostics are required for your maintenance strategy.

• Mounting: Secure the module onto a 35 mm DIN rail using the integrated lock. When mounting modules side-by-side, ensure the double slot and key connection is properly engaged to maintain mechanical stability and proper alignment for the internal bus.

• Conductor Preparation: For reliable connections, ensure conductors are stripped to 8 mm. Use appropriate ferrules for stranded wires to ensure a robust, low-resistance contact within the spring-loaded terminal interface.
