iSMA Mix 18-IP

Mix 18-IP

In order to ensure high versatility and price performance the MIX18-IP module has 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 module has 5xUI (Universal Inputs), 5xDI(Digital Inputs), 4xAO (Analog Outputs) and 4xDO (Digital Outputs).

The module is factory-equipped with the two most popular open communication protocols: Modbus TCP/IP and BACnet IP, which are selected using DIP switches.

The Mix 18-IP has a built-in Modbus Gateway TCP/IP to Modbus ASCII/RTU, enabling you to connect additional modules/devices that communicate via Modbus RS485.

Addressing the modules is done via rotary switches, which facilitates and accelerates the process of commissioning the system.

There is also a built-in mini USB that allows for initial configuration of the unit without a power supply.
