Beckhoff enhances its range of products for EnOcean radio technology

In conjunction with the KL6583 EnOcean transmitter and receiver module, the new Beckhoff KL6581 EnOcean master terminal offers greater flexibility in terms of planning and bidirectional communication. EnOcean technology facilitates wireless, battery-less sensors, switches, energy harvesters and more for building and home automation. The range of the battery-free transmitter and receiver is extendable up to a maximum data bus length of 500 m (1640 ft) with the connection of up to eight EnOcean modules to the master terminal. That not only brings cost advantages, but also makes the planning of building automation significantly more flexible and simpler.

Previously only the reception of EnOcean data was possible via the Beckhoff wireless adapter, now all of the EnOcean sensors and actuators can be connected using the new KL6581 EnOcean master terminal and the KL6583 transmitter and receiver module. With a radio signal range of at least 30 m (98 ft), the wiring of buildings can be simplified significantly.

EnOcean radio technology is integrated into the Beckhoff Bus Terminal system via electronic terminal blocks. Higher-level Bus Couplers for all common bus and Ethernet systems enable flexible connection to the higher level controller.

The KL6581 represents the link between the wireless KL6583 EnOcean transmitter/receiver modules and the application. Up to eight EnOcean modules can be connected to one EnOcean master terminal so the standard range of the EnOcean radio signals can be extended as a result. When connecting the maximum of eight devices, it is possible to achieve a data bus length of up to 500 m (1640 ft) between the master module and the last KL6583. This makes EnOcean solutions not only more cost-effective, but also more flexible and simpler to plan. – If, for example, a wall or a distance is incorrectly planned, it is now possible to simply connect an additional module.

The KL6583 modules are connected to the KL6581 master terminal via two wires for the power supply and two wires for the data bus. The sub-bus employed by Beckhoff is CAN, an economical and interference-resistant bus system with high data security that relays the EnOcean telegrams using an event-controlled method.

The EnOcean transmitter and receiver module can be installed in visible locations within buildings thanks to its attractive appearance – a plain, round housing with a diameter of 72 mm and a height of 57 mm
(2.8 in x 2.2 in).

The KL6581 EnOcean master terminal and the KL6583 EnOcean transmitter and receiver module are expected to be available in the
2nd quarter of 2010.
