The product group of I/O modules MINI series has been designed to complement the I/O modules of the MIX series. Unlike the MIX series, the MINI line is dedicated to all the applications where hand operating switches are required. Also, the MINI line products’ light-controlling algorithm makes them applicable as lighting controllers. Very much like in case of the MIX modules, the modules are factory-equipped with the two most popular open communication protocols: Modbus (ASCII, RTU, TCP/IP) and BACnet (MSTP, IP), which are selected using DIP switches. There are two versions of the modules, namely: modules with interface RS485, and modules with interfaces 1x Ethernet and RS485. Devices with interfaces 1x Ethernet and RS485 have the added functionality of ” Modbus Gateway TCP/IP to Modbus ASCII/RTU”, enabling you to connect additional modules/devices that communicate via Modbus RS485. One major advantage of supporting our modules with open communication standards is the versatility to install them in both new and completed installations, as part of an existing BMS. To even further increase the versatility, all relay modules allow direct control of any system components supplied with 230 VAC (max. 3A or 8A ). As it does not require the use of additional relays, it thereby leads to considerable savings. Addressing the modules is 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.
