The module iSMA-B-4O-H-IP has 4xDO (Digital Outputs). DO are NC/NO relay outputs 230 V AC/30 V DC max. 8 A.
The modules are factory-equipped with the two most popular open communication protocols: Modbus TCP/IP and BACnet IP, which are selected using DIP switches.
Built-in Modbus Gateway TCP/IP to Modbus ASCII/RTU, enabling you to connect additional modules/devices that communicate via Modbus RS485.
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.
