Description

The BECKHOFF KM2652 is a 2-channel digital output Bus Terminal module designed for 230 V AC operation with a maximum output current of 6 A per channel. As part of the established BECKHOFF Bus Terminal system, this module integrates change-over relay contacts and features integrated manual and automatic operation capabilities, allowing direct local control alongside standard controller commands.

The KM2652 facilitates flexible control and status monitoring in industrial automation architectures. The module provides switch setting readability back to the controller via the process image, reporting the status of hand, auto, and relay ON/OFF states. It connects to the internal K-bus system for communication with the bus coupler while routing power through associated power contacts.

Installation Guidelines

1. Ensure the entire control system is de-energized and locked out before performing any mechanical or electrical installation work.
2. Inspect the BECKHOFF KM2652 module for any transit damage or bent pins prior to mounting.
3. Snap the Bus Terminal securely onto a standard DIN rail next to the appropriate bus coupler or preceding terminal.
4. Verify that power contacts and K-bus connections interlock correctly with adjacent terminals.
5. Connect field wiring to the appropriate terminal points according to the designated voltage and load limits, ensuring proper cable shielding and strain relief.
6. Restore power and verify module operation, local manual override functions, and process image communication through the control system.
