iSMA – MIX Series

The product group of I/O modules of the MIX series has been designed for building distributed control systems using JACE or AAC20 devices.
All the MIX Series modules have been equipped with the most commonly used types of I/O in building automation (MIX of all types of I/O in one unit).

The modules are factory-equipped with the two most popular open communication protocols: Modbus (ASCII, RTU, TCP/IP) and BACnet  MS/TP, IP), which are selected using DIP switches. There are two versions of the modules: modules with RS485 interface and with 2x Ethernet and RS485 interfaces.

Devices with 2x Ethernet and RS485 interfaces have the added functionality of “Modbus Gateway TCP/IP to Modbus ASCII/RTU”, enabling for the connection of additional modules/devices that communicate via Modbus RS485. The Modbus Gateway functionality is active also for devices
configured as BACnet IP modules. IP modules, communicating either in Modbus or BACnet, are always master units on the network. One major advantage of supporting the modules with open communication standards is the versatility to install them in both new and completed installations, as part of an existing BMS.

Addressing the modules takes place via rotary switches, which facilitates and accelerates the process of commissioning the system. Built-in mini USB allows for initial configuration of the unit without power supply.
