iSMA-B-8U-IP

I/O module with Modbus TCP/IP (with built in Modbus Gateway to RS485) or BACnet IP communication- 8UI
£285.00

The module iSMA-B-8U-IP 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.
