iSMA-B-Mini-8U-IP

iSMA

The module has 8xUI (Universal Inputs). UI can work in 5 different modes: temperature, voltage, current, resistance, dry contact. The module is 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.

Key features
