FC SERIES COMPACT CONTROLLER S
(STEP OUTPUT TYPE)
DATA SHEET
PNC1
Compact controller S (fixed function type) is a compact
single-loop controller using a microprocessor.
It accepts uniform signals, and signals from a thermocouple and resistance bulbs as input, and includes sufficient
control and computation functions which permit composition
of a flexible system for PID control, square-root extraction,
non-linear control, etc.
FEATURES
1. PID auto turing function
Optimum PID parameter can be obtained for processing.
2. High reliability
LED's (red and green) are used for the bar graph indicator
and for parameter indication (red). A non-volatile memory
retains the control and computation parameters even if
power should be interrupted.
3. All operations are performed from the front of the panel
Operations such as parameter setting, auto/manual
changeover are performed from the front of the panel.
4. Transmission function
Incorporation of transmission function permits setting of
concentrated monitoring data at the host system.

nonvolatile memory (lasts for 10 years or
longer at ambient temperature of 50°C or
less).
Power failure recovery time:
Initial or continuous start set for power
failure within 5 minutes.
Recovery from power failure lasting longer
than 5 minutes is done by initial.
