iSMA-B-MIX

The I/O modules of the MIX series were specially developed to expand the I/O capacity of any DDC controller or automation server, as long as they are capable of MODBUS or BACnet communication. and for cost efficiency, the MIX modules have the I/O channels most often used in building automation . (UI, DI, AO, DO on one module).

IP version modules can also be used as transparent MODBUS TCP/MODBUS RTU or ASCII gateways, and also contain 2 ethernet ports, thanks to which the device works as a switch .

 

As the modules support open protocols, they can be easily applied in both new and existing installations. Addressing with rotary switches simplifies and speeds up commissioning.

The built-in USB port allows you to set up the products without using an additional power supply.
