In order to ensure versatility, while maintaining an attractive price level module MIX38 is equipped with the most commonly used types of I / O in building automation (a mixture of all types of I / O in one unit). The module has 8xUI(Universal inputs) 12xDI (digital inputs), 6xAO (analog output) and 12xDO (digital outputs).

Additionally, the module is equipped with two of the most popular communication protocols: Modbus  ASCII / RTU and BACnet  MSTP , the choice of which is done using DIP switches.

Addressing the modules is done via rotary switches, which simplifies and speeds up the boot process.

The built-in mini USB interface for initial configuration of the device without power.
