Description

The BECKHOFF KL6581 is a K-bus Bus Terminal that serves as an EnOcean master interface. It is designed to enable wireless communication with EnOcean-compatible sensors and actuators in building automation and industrial control environments. The terminal itself does not contain high-frequency transmitter or receiver hardware; instead, it acts as a central controller and interface module that connects to external transceivers.

To achieve wide radio coverage across a building, the BECKHOFF KL6581 supports the connection of up to eight external BECKHOFF KL6583 EnOcean transmitter and receiver modules. This distributed architecture allows physical transceivers to be positioned at optimal locations away from the control cabinet, overcoming distance limitations and avoiding building structure interference.

Features

  • EnOcean master interface terminal for K-bus systems
  • Supports connection of up to eight KL6583 EnOcean transceiver modules
  • Internal data transfer rate of 125 kbaud between the master terminal and transceivers
  • Enables extended physical network layout with up to 500 meters of total connection cable length
  • Power supply provided directly via the K-bus connection
  • Compact housing design suitable for standard DIN rail mounting

Applications

  • Building automation systems requiring wireless EnOcean sensor integration
  • Industrial remote monitoring where physical wiring is impractical
  • Retrofitting existing machinery or facilities with wireless controls

Installation Guidelines

  1. Ensure all system power is switched off before mounting or removing the terminal.
  2. Mount the BECKHOFF KL6581 onto a standard 35 mm DIN rail. Ensure it snaps securely into place.
  3. Connect the K-bus power contacts and check that connection pins are correctly aligned with neighboring terminals.
  4. Route the connection cables to the external KL6583 EnOcean transceiver modules, ensuring a maximum length of 500 meters is not exceeded.
  5. Perform a visual inspection of the wiring before applying the 24 V DC power supply to the system.

FAQ

What is the primary function of the BECKHOFF KL6581 Bus Terminal?

The BECKHOFF KL6581 serves as an EnOcean master terminal, interfacing the Beckhoff Bus Terminal system (K-bus) with up to eight external KL6583 transceiver modules for wireless communication.
