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

The iSMA 4O H IP 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 with built-in Modbus gateway

Product Description

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.
