1Introduction
1.1 Introduction
The new generation low-cost PID microprocessor-based Fuzzy logic controller series incorporate two
bright easy to read LCD Displays which indicate Process Value (PV) and Setpoint (SP). The Fuzzy Logic
technology incorporated on these series controllers enables a process to reach a predetermined set
point in the shortest time with a minimum of overshoot during startup (Power ON) or external load
disturbances (example: an oven door being opened).
Below are the different controller models of this series.

1-1. Controller Models
These controllers are powered by an 11-26 or 90-250 VDC /VAC supply, incorporating a 2 Amp control
relay output as a standard. The second output can be used as a cooling control or an alarm. Both
outputs can be selected as a 5VDC or 14VDC logic output, linear current or linear voltage to drive an
external device. There are six types of alarms and a dwell timer that can be configured for the third
output. The controllers are fully programmable for Linear current, Linear Voltage, PT100 and
thermocouple types J, K, T, E, B, R, S, N, L, U, P, C, and D. The input signal is digitized by using an
18-bit A to D converter. Its fast sampling rate allows the controller to control fast processes.
1.2 Features
The new generation of low-cost PID controllers has a lot of unique features.
The unique features are listed below.
LCD Display
High Accuracy 18 Bit A-D Conversion and 15 Bit D-A Conversion
Fastest Sampling Rate of 200 msec
Universal Input
Fuzzy Logic +PID Technology
Possibility of both RS-485 and analog retransmission

LCD Display
All the controllers in this series will be equipped with high brightness LCD Display.
Digital Communication
RS-485 Digital communication is available as an additional option. These options allow the units to be
integrated with supervisory control systems and software.
A Micro USB programming port is available for automatic configuration, calibration and testing without
the need to access the keys on the front panel.
Fuzzy PID Technology
By using proprietary Fuzzy modified PID technology, the control loop will minimize overshoot and
undershoot in the shortest allowable time. The following diagram is a comparison of results with and
without Fuzzy Logic technology.
1-1.Fuzzy PID Control
High Accuracy
This series of controllers are manufactured using an innovative technology which contains an 18-bit A to
D converter for high-resolution measurement (true 0.1°F resolution for thermocouple and PT100
sensors) and a 15-bit D to A converter for a linear current or voltage control output. The innovative
technology provides improved operating performance, enhanced reliability and higher density with low
cost.
Fast Sampling Rate
The sampling rate of the input A to D converter reaches 200 msec. This fast sampling rate allows the
controllers to control fast processes.
Fuzzy Control
The function of Fuzzy control is to adjust PID parameters from time to time to make manipulation of the
output more flexible and adaptive to various processes. The result is to enable a process to reach a
predetermined set point in the shortest time, with a minimum of overshoot and undershoot during power-
up or external load disturbances.
Digital Communication
The controllers can be equipped with an optional RS-485 interface to provide digital communication. By
using twisted pair wires, up to 247 units can be connected via an RS-485 interface to a host computer.
