EPCON Electro Pneumatic Controller

BY EPCON, a digital type electro-pneumatic
controller is designed to control process variables
such as pressure, temperature, liquid level and etc.. lt
provides all the latest digital electronic control
functions with reliability of a pneumatic controller.
BY EPCON is composed of several major parts
including Digital Signal Processor, flash ROM for
program/data storaging, LCD display, signal
processing & WatchDog circuits, digital signal fitter,
A/D converter, control buttons, RS232C
communication interface (optional), a pair of solenoid
valves and its driving unit, signal input output
terminals and etc..
The algorithm for PID control was adopted as control
software.
BY EPCON operates on 110-220V AC (50/60 Hz) or
24V DC power. lt accepts signals from standard
4-20m4 transmitter, and provides a pneumatic
output to operate diaphragm or piston actuated
control valves.
The controller accommodates a maximum of 60 psig
output to control pneumatic diaphragm or piston type
actuator without using l/P transducer or valve
positioner. BY EPCON has its own24 volt DC power
supply for the transmitter, simplifying the complexity
of power supply with less cost.
