FC SERIES COMPACT CONTROLLER S
(PROGRAMMABLE, CONTINUOUS OUTPUT TYPE)
DATA SHEET
PNA2
The Compact Controller S (programmable type) is a compact single-loop controller using a microprocessor. It accepts uniform signal, and signals from thermocouple and
RTD (Resistance bulb) as input, and is equipped with abundant control and computation functions to allow composing
a flexible system with a high cost/performance.
FEATURES
1. Abundant control and computation functions
The controller has a variety of control and computation
functions in addition to PID auto tuning, and also has a
transmission function for data exchange with a host system.
2. Control and computation programming can be made
at the site
Since the control and computation functions are built into
wafers (functional units), an optimum program or the control object can be formed just by keying on the front panel.
3. High reliability
LED’s (red and green) are used for the bargraph indicator
and also for the parameter indication (red), and a non volatile memory enables retaining the control and computation parameters even if power should be interrupted.

changeover, hard manual operation etc. are all made from
the front panel.

VARIOUS CONTROL EXAMPLES
Basic type PID control (Fixed
function)
This is a PID control function
which is fixedly defined beforehand. The definition can be
made through simple operation,
and wafer connection is unnecessary.
(Computation elements such as
square root, filter, limiter, nonlinear etc. can be made valid or
invalid through specification.)
PID control
Fixed value control is carried
out by using only the MAln
control block. PID control by
means of an external set point
is also performed. (Computation elements such as square
root, filter, limiter, non-linear
etc. can be made valid or
invalid through specification.)
Cascade control
Cascade control is carried out
by combining two PID control
blocks. By having the output
of the SUB PID controller follow
up the set point of the MAln
PID controller, A and R can be
changed over balancelessly.
