EDS10-15F Datasheet, PDF (1/6 Pages) Fuji Electric – FC SERIES SELF-BALANCING RECORDER

FC SERIES _{SELF-BALANCING RECORDER}
DATA SHEET
The FC SERIES self-balancing recorder is capable of
continuously recording up to three types of inputs like
process signal, DC voltage, current, thermocouple signal,
resistance bulb signal, etc. Alarm units for the individual
pens, external chart speed selector convenient for plant
instrumentation, marking pen and many other optional
accessories are prepared inside the self-balancing recorder.
It is also usable as a trend recorder for 18 input points when
combined with input selector (Type: PFC).

FEATURES
1. Compact design measuring 96 mm wide by 144 mm high
(front panel) by 400 mm deep (casing).
2. The recorder uses a folding type chart, of which one stack
allows continuous recording for a month at a standard
chart speed of 20 mm/h.
3. Data are indicated in bargraphs with color ribbon.
4. The servo-mechanism consists of a contactless induction
potentiometer and a powerful coreless-motor, thereby
assuring high reliability.
5. Chart speed is set accurately and can be switched easily
by a combination of a clock circuit comprising a crystal
oscillator and a pulse-motor.
6. The recorder can operate within a wide DC voltage range
of 20 to 30V, or commonly at 50 and 60 Hz with an AC
power supply.
7. The recording pen is a cartridge type felt-tip pen requiring
a minimum of maintenance.
