iSMA MINI 4TO H
The module iSMA 4TO H has 4xTO (Triac Outputs). TO can direct control 24-230 V AC voltage with max. 0,5 A load.
The iSMA 4TO H module is factory-equipped with the two most popular open communication protocols: Modbus ASCII/RTU and BACnet MSTP, which are selected using DIP switches.
Compatibility
Niagara Framework and any BMS
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.
