Looking for I/O Modules for your next project?

Why not let our I/O Calculator do the hardwork for you? Calculate my I/O here.


This powerful cost effective fan coil controller has all the inputs and outputs you need for every project, as well as the intelligence and embedded control to meet every application.

With high speed Modbus communications and a dedicated free driver for Tridium Niagara 4, integrating these controllers into your chosen BMS or IoT solution could not be easier.

The free Niagara driver includes automatic discovery and drop-down simple configuration for input types and scaling, well as automatic history extension creation for inputs and outputs. This saves a huge amount of time and makes sure the engineering gets done right, first time around.

With support for all electrical and mechanical HVAC system, and 9 modes of selectable modes of operation included, these controllers represent the best possible solution at a breakthrough low price.


18 I/O for every application

  • 4 x Special Inputs for Temperature, Setpoint, Pipe Flow and Return Temp
  • 4 x digital inputs – dry contact
  • 3 x 0-10v outputs for Htg, Clg and Fan
  • 2 x Triac outputs for 24v Htg and Clg
  • 3 x 6A Relays for 3 Speed Fan
