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
The module allows for seamless configuration over BACnet, Modbus, or dedicated free of charge tool. The ability to be powered from a USB port facilitates local testing and a straightforward updating process, and the high-end RS485 transceiver allows up to 128 devices to communicate reliably with the client on a single bus.
