The FBU Series is a freely programmable range of Unitron Communications and Field Controllers. The controllers are ideally suited for a wide range of applications for intelligent control of HVAC equipment, and electrical systems including lighting control and metering applications. The FBU Series supports multi-protocol communications simultaneously including Unitron and Modbus RTU. Based on ABB’s FLXeon Line of field controllers, the FBU Series features support for one FLX (Field Level eXpansion) series extension modules providing up to 24 points of control.
