8UI (BACnet MSTP / Modbus RS485)


Multiprotocol I/O Module in a Compact Size
Powerful I/O module that works as a remote I/O over a serial port with open protocols, BACnet MS/TP and Modbus RTU/ASCII. The module is equipped with 8 universal inputs with a built-in temperature table for over twenty types of temperature sensors in both Celsius and Fahrenheit degrees. A compact size and ease of installation allow the module to be fitted even into limited space installations.

8 Universal Inputs 
Support for over 20 types of temperature sensors and voltage, resistance, current, and dry contact measurements on each universal input.

Simplified Configuration and Commissioning Process
