I/O Modules: MIX – IP Series – iSMA-Controlli

Equipped with Fast Ethernet ports and RS485 interface functioning as a Modbus TCP/IP to Modbus RTU/ASCII gateway, supporting seamless integration with other devices.

Application

Suitable for distributed control systems in building automation, HVAC, and data centers.
Used in projects requiring IP-based communication with building controllers.
Ideal for expanding system capacity through both new and existing BMS installations, enabling real-time data monitoring and control.

The MIX-IP series multiprotocol I/O modules extend the capabilities of controllers like MAC36NL, iSMA-B-J8, or AAC20 using IP connections and open communication protocols such as BACnet IP and Modbus TCP/IP. They provide the most commonly used types of I/Os in building automation, and support multiple modules via daisy chain connections.
