More project flexibility
The OPEN IO modules, which have a modular design and feature powerful communication properties, are ideally suited for all controller applications for technical building automation. They are compact, easy to install and can be universally used with various measuring elements. A total of 16 different versions of the OPEN IO modules are available. Whether as analogue or digital module, as IO combination module or pure input or output module – you will find the right module for your project!
Easy connection in the field
DEOS IO modules are connected to the OPEN EMS controller via the CAN-bus (Controller Area Network) – the most widely used bus system for networking control units. This bus system can accommodate up to 99 DEOS IO modules per line, ensuring high flexibility for future expansion. The bus speed depends on the distance of the IO modules to the controller and is up to 1 Mbit/s depending on the bus quality. For several years now, we have successfully been using the CAN-bus, which offers high speeds and great deal of safety.

Measured value transformation module MT-R
By using a measured value transformation module MT-R, you can considerably expand the measuring range for resistance sensors of an OPEN IO module and connect resistance sensors with larger measuring ranges. NTC and PTC sensors can absorb resistance values from approx. 200 ohms up to 1 MOhm. Using the MT-R allows you to connect these sensors directly to the analogue inputs of the OPEN IO modules or the integrated analogue inputs of the OPEN EMS. The measured value transformation module MT-R offers 8 analogue inputs and outputs to which you can connect up to 8 PTC/NTC sensors.
Coupler module DS-PKM
The coupler module DS-PKM at the beginning of a series of IO modules is used to feed the 24 VDC supply voltage and the CAN-bus. At the end of the series, it is used to tap the CAN-bus or to terminate it. Such a series of modules may include max. 15 IO modules.
IO modules for your room
In addition to IO modules for installing in switch cabinets and control panel construction, we also offer IO modules with wall mounting for your individual room solution. Whether in office buildings, schools, hotels or administrative buildings – our OPEN IO7 and OPEN IO7-B modules are always the right choice for your building.
