iSMA – MINI Series

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 applications, where hand operating switches are required. The built-in light, cooling and heating algorithms make them applicable as the standalone controllers. Additionally, the modules support time relay modes dedicated to present detectors.

Like in case of the MIX series modules, MINI series is 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: with RS485 interface and  with Ethernet and RS485 interfaces. Devices with 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 which 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.
