iSMA-B-4O-H

The module iSMA-B-4O-H has 4xDO (Digital Outputs). DO are NC/NO relay outputs 230 V AC/30 V DC max. 8 A.

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.
