Rosemount 2160 Field Communication Unit (FCU)
- The Field Communication Unit, FCU acts as a master of communications on the Field Bus and as a slave on the Group Bus. The FCU is an intelligent data concentrator that continuously collects input data from a group of Radar Tank Gauges and Data Acquisition Units and stores it in a buffer memory.
- The heart of the FCU is a microprocessor with RAM and EEPROM for data and program storage.
- The FCU is delivered in an IP-65 weather protected, wall-mounted box of the same type as for the Data Acquisition Unit.
