iSMA Controlli Mini 4O-H
The iSMA 4O H has 4xDO (Digital Outputs). DO are NC/NO relay outputs 230 V AC/30 V DC max. 8 A.
The iSMA 4O H is factory-equipped with the two most popular open communication protocols: Modbus ASCII/RTU and BACnet MSTP, which are selected using DIP switches.
Protocols: Modbus ASCII/RTU and BACnet MSTP
Product Description
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.
