1-1 General1-1 General
The Fuzzy Logic plus PID microprocessor-based controller series,
incorporate a bright, easy to read 4-digit LEDdisplay,indicating
process value or set point value. The FuzzyLogic technology
enables a process to reach a predetermined set point in the
shortest time, with the minimum of overshoot duringpower-up or
external load disturbance.
The TC/PC 24 is a 1/32 DIN sizepanel mount controller. These units
are powered by 11-26 or 90-250 VDC/VAC supply, incorporating a
2 amp control relay output as standard. Thesecond output can be
used as cooling control, an alarm or dwell timer. There are
six types of alarm plus a dwell timer can beconfigured for the
second output.The units are fully programmable for PT100 and
thermocouple types J,K, T, E, B, R, S, N, Lwith no need to modify the
unit. The input signal is digitized by using a18-bit Ato D converter.
Its fast sampling rate allows the unit to control fastprocesses.
By using proprietary Fuzzy modified PID technology, the control
loop will minimize the overshoot and undershoot in a shortest
time. The following diagram is a comparisonof results with and
without Fuzzy technology.

High AccuracyHigh Accuracy
The series are manufactured with custom designedASIC(Application
Specific Integrated Circuit ) technology which contains a 18-bitA to
D converter for high resolution measurement ( true 0.1BF resolution
for thermocouple and PT100 ) and a 15-bit Dto Aconverter for linear
current or voltage control output. TheASIC technology provides
improved operating performance, low cost, enhanced reliability and
higher density.
Fast Sampling RateFast Sampling Rate
The sampling rate of the input Ato D converter reaches 5 times/second.
The fast sampling rate allows this series to control fast processes.
Fuzzy ControlFuzzy Control
The function of Fuzzy control is to adjust PID parameters from time to
time in order to make manipulation output value more flexible and
adaptive to various processes. The results is to enable a process to
reach a predetermined set point in the shortest time, with the minimum
of overshoot and undershoot during power-up or external load
disturbance.

Auto-tuneAuto-tune
The auto-tune function allows the user to simplifyinitial setup for a
new system. Aclever algorithm is provided to obtain an optimal set
of control parameters for the process, and itcan be applied either as
the process is warming up ( cold start )or as the process has been
in steady state ( warm start ).
Lockout ProtectionLockout Protection
According to actual security requirement, one of four lockoutlevels
can be selected to prevent the unit from beingchanged abnormally.
Bumpless TransferBumpless Transfer
Bumpless transfer allows the controller to continue to control by
using its previous value as the sensor breaks. Hence, theprocess
can be well controlled temporarily as if the sensoris normal.
Soft-start RampSoft-start Ramp
The ramping function is performed during power up as well as any
time the set point is changed. It can be ramping up or ramping
down. The process value will reach the set point with a predetermined
constant rate.
Digital FilterDigital Filter
A first order low pass filter with a programmable time constant is used
to improve the stability of process value. This is particularly useful in
certain application where the process value is too unstable to be read.
