MODBUS RTU COMMUNICATING CONTROLLERS

SyxthSense has a wide range of controllers that can be linked to the Modbus masters using Modbus RTU RS-485 communication. Our rnage of controllers include main plant heating and ventilation controllers, room controllers, natural ventilation controllers and underfloor heating controllers. We also offer fully programmble controllers with Modbus communications. All controllers have configurable Modbus RTU settings and have been designed for effective temperature control.
