FC SERIES RATIO SETTER
DATA SHEET
PNG3
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.

longer than 5 minutes is done by initial.
Note: ** Control mode at initialzation can be
registered
