FC SERIES RATIO SETTER
DATA SHEET
The FC series ratio setter is used to set ratio for ratio control, and its set point signal is transmitted to a controller. This instrument uses a solid state indicator and a pushbutton operation system to provide reliable monitoring and operating functions. It also accepts a thermocouple, a resistance bulb and a 4 to 20mA DC input optionally.

FEATURES
1. High reliability This instrument is designed with few mechanical parts. It is mainly composed of electronic parts such as a solid state indicator which was formerly consisted of mechanical parts. 2. International standards This instrument is compact in size, conforming to international standards IEC. It operates on 24V DC power to deliver 1 to 5V DC signals as recommended by IEC standards. 110 and 220V AC power are also available for convenience of operation. 3. Front panel operation Process values and set points can be read accurately with digital indications on panel front. Various parameter settings and setting operations are also possible from the front panel of the instrument.
