iSMA-B-4TO-H

The module iSMA-B-4TO-H has 4xTO (Triac Outputs). TO can direct control 24-230 V AC voltage with max. 0,5 A load.

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

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.
