Working Principle
The module receives a control signal (4-20mA or 1-5V) from the DCS, compares it with the actual valve position feedback, and utilizes its internal microprocessor to drive the actuator until the valve reaches the exact desired position.
Installation Requirements
- Must be installed in a location with adequate ventilation to dissipate heat.
- Requires proper shielding of signal cables to prevent electromagnetic interference.
Precautions for Use
- Ensure the power supply voltage strictly matches the 24V DC specification.
- Regularly calibrate the valve positioner to maintain control accuracy.
