Radioline multipoint multiplexers

Radioline multipoint multiplexers Quick and easy commissioning of a complete I/O system – without any programming

With the Radioline I/O modules, the Radioline RS-485 bus coupler provides you with a multiplexer system specifically for process use. The special feature: easy I/O mapping using the thumbwheel and multipoint operation over any 2-wire cables or alternative media.

Your advantages

  • New options for I/O distribution with up to 99 stations in the bus system with multipoint multiplexer operation
  • Extension of the Radioline wireless system with a wired line structure
  • Can be used on any controller as a Modbus/RTU server
  • Bridge large distances using existing 2-wire copper cables or a wireless connection
  • Use in zone 2 potentially explosive areas
I/O mapping

Quick and easy commissioning of I/O systems

I/O mapping

Use the thumbwheel to assign the I/O modules within a network to one another. All you need to do is set the I/O modules that need to communicate with one another to the same number. For example, set a digital input to IO MAP address 12 and then also set the assigned digital output to IO MAP address 12 – the signals will then be distributed correctly throughout the entire system.

One device – a wide range of applications


Multipoint multiplexers

Distribution of I/O signals via existing 2-wire cables

Multipoint multiplexers

Distribute I/O signals in an RS-485 network with up to 99 Radioline stations over existing 2-wire cables. I/O mapping significantly simplifies signal distribution in large systems.

Assign inputs and outputs quickly by simply turning the thumbwheel. In this way, you can distribute and multiply I/O signals freely in your network using I/O extension modules. Without the need for programming.

Radioline wireless system for intermedia communication

Wireless and wired stations form a combined system.

Intermedia communication

A Radioline wireless system on an existing client can be expanded to include new RS-485 stations. The wireless and RS-485 modules form a combined system with up to 99 Radioline stations. I/O mapping significantly simplifies intermedia signal distribution in large systems.

Assign inputs and outputs quickly by simply turning the thumbwheel. In this way, you can distribute and multiply I/O signals freely in your network using I/O extension modules without the need for any programming.

Stand-alone remote station

Operates on any Modbus/RTU client

Stand-alone as a remote station

Operates on any Modbus/RTU client. Supports modular expansion with up to 32 I/O modules per RS-485 station.

SHDSL extenders

Extend the range by up to 20 km via existing 2-wire cables with SHDSL extenders

Alternative transmission media

To increase the range, you can of course replace the RS-485 line with alternative transmission media. A wide range of converters is available for fiber-optic cables, SHDSL, wireless, and Ethernet technology.
