I/O module with Modbus TCP/IP or BACnet IP communication- 8UI

• 8 Universal Inputs
• RJ-45 Ethernet Port
• Supports Modbus TCP/IP and BACnet IP
• Built-in Modbus Gateway – Modbus TCP/IP to Modbus ASCII/RTU
• RS-485 serial port to connect additional modules/Modbus slave devices

Description 

The iSMA-B-8U-IP module features 8xUI (Universal Inputs) capable of operating in 5 different modes: temperature, voltage, current, resistance, and dry contact.

This module comes pre-equipped with two widely used open communication protocols, namely Modbus TCP/IP and BACnet IP, which can be selected using DIP switches.

The module also includes a built-in Modbus Gateway TCP/IP to Modbus ASCII/RTU, allowing seamless integration of additional modules/devices that communicate via Modbus RS485.

Addressing the modules is made convenient through the use of rotary switches, simplifying and expediting the process of commissioning the system.

The module is equipped with a built-in mini USB port, enabling initial configuration without the need for an external power supply.
