Wireless multiplexer on a DIN rail

Wireless multiplexers The wireless signal cable

Transmit your I/O signals reliably to hard-to-reach or rotating stations with Wireless MUX.

You can install the Wireless MUX particularly quickly: Connect it, switch it on, and the signals will be transmitted wirelessly immediately. The connections are established and signals transmitted automatically due to the fixed assignment of the devices.

Your advantages

  • Easy commissioning – no configuration or settings are required
  • High number of channels in a compact housing
  • Typical transmission time of less than 10 ms
  • Range of up to 200 m with omnidirectional antennas; up to 400 m with directional antennas with a clear line of sight
  • The latest Bluetooth 4.0 technology with low energy consumption

Wireless multiplexers: unpack, connect, and switch on

Wireless multiplexer, the wireless signal cable

The wireless multiplexer transmits 16 digital and two analog signals bi-directionally, i.e., in both directions, which means that it can replace a 40-wire signal cable. The connection is monitored continuously during the process. If there is severe interference or the connection is interrupted, the outputs are reset to the defined LOW state. This is indicated on the module by a diagnostic LED. The link-quality display provides the user with constant information on the quality of the link.

Connection to the controller is quick and easy using existing input and output channels.

Ready to use: unpack, connect, and switch on

Typical fields of application

The wireless multiplexer is used wherever a small number of digital or analog input and output signals need to be exchanged wirelessly with a remote or movable station. Factory automation in particular is characterized by machine parts that are constantly in motion.

Replacement of slip rings, trailing cables, and cable conduits and drums.

Examples of use:

  • Crane systems with wear-free wireless communication between overhead crane and central controller or for the control of so-called “trolleys”, for example
  • Concrete plant with wireless communication between bucket cars and central controller or wireless communication between concrete spreaders and central PLC, for example


Control of moving machinery and systems, replacement of cable drums, and replacement of failure-prone and high-maintenance cable runs.

Examples of use:

  • Foundry with wireless communication between mobile charging trolleys and a central controller, for example
  • Composting plants with wireless communication between mobile converters and hose reel carts for water supply, for example

Sewage treatment plant with outdoor tanks

Replacement of slip rings and control of remote, difficult to access, or moving system parts.

Example of use:

  • Wastewater treatment plant with pump control in grit chambers or wireless communication between the scrapers and central PLC, for example
