Bidirectional wireless system – secure transmission in both directions

Transmit two digital switching signals and one analog sensor signal securely in both directions – with our bidirectional RAD Line I/O modules.

Advantages of the bidirectional wireless system

Flexible I/O communication: with the bidirectional wireless system

Design your bidirectional wireless system individually according to your requirements: with the integrated bus foot, you can connect up to eight I/O extension modules quickly and easily.

  • Long range from a few hundred meters to several kilometers
  • Easy startup
  • Good diagnostic options
  • High local system density of several hundred networks possible
  • No operating costs, thanks to license-free ISM band
  • Can be operated in parallel with WLAN 802.11 and Bluetooth systems without interference
  • Can be extended with I/O extension modules
  • Use in Ex zone 2

Use as a bidirectional point-to-point connection

Bidirectional point-to-point connection

One option for transmitting I/O signals wirelessly is to use a point-to-point connection in both directions. If the system is installed with this configuration, the signals connected, and the operating voltage applied, then the wireless connection is established automatically without any further settings.

If you have extended your system with additional I/O modules, they can be assigned to one another quickly via the address encoding switch on the front of the housing.

Use as a unidirectional point-to-multipoint connection

If you want to use your bidirectional wireless system with a point-to-multipoint configuration, this will result in a unidirectional wireless system, i.e., one transmitter and any number of receivers. In this configuration, the receiver stations are mirror images of the transmitter side.

The system can also be extended with I/O extension modules. This means, for example, that a signal path can be split or signals can be multiplied.

An address encoding switch on the front of the housing is used to assign the I/O modules to one another.

Use with a repeater

Bidirectional point-to-point connection with repeater

Do you want to increase your transmission range and reliably communicate over hills, for example? Then use our powerful repeaters. 

The set consists of three pre-configured transceivers, where the repeater is a transceiver with a special hopkey. If you connect several repeaters one after the other, the range will be multiplied.

Important: the repeater itself cannot receive or output signals. However, bidirectional data exchange is possible in a point-to-point connection with a repeater and I/O extension modules.
