E&P-01
Description |
---|
E&P-02 Controller, digital type electro-pneumatic controller is designed to control process variables such as pressure, temperature, liquid level and so on. It provides all the latest digital electronic control functions with reliability & precision of a pneumatic controller. Controller is composed of several major parts including Digital Signal Processor, flash ROM for program / data storage, analog-digital signal filter, Watch Dog sircuits, RS232/485 Communication interface & a pair of solenoid valves and etc.
The algorithm for PID control & auto-tuning was adopted as control software. Electro-Pneumatic Controller operates that it accepts the signals standard 4~20mA and/or PT100 from a sensor(transmitter), and CPU forward output signal, to be calculated by PID. It will provide Pneumatic output to operate diaphragm or piston actuated control valves. Because this features E&P-02 doesn’t use I/P transducer and/or valve Positioner, it operates actuator directly thus reducing the cost. |
