High Quality 4 -20 mA 485 Communication Automatic Intelligent Valve Positioner for Control the Valve Opening

Product characteristics
The intelligent valve positioner is a regulator based on microprocessor control, incorporating a displacement sensor and utilizing PWM combined with algorithms to automatically control the valve opening. The valve opening and closing can be set through external input signals, or the opening can be manually set. It accurately achieves adjustments in flow, pressure, and temperature.

Description of Commodity: High Quality 4 -20 mA 485 Communication Automatic Intelligent Valve Positioner for Control the Valve Opening

Electrical interface connection

Specification for the use of waterproof electrical connectors

The electrical interface features male and female protrusion and indentation designs. Please insert it into the waterproof pin male head according to the S1 and S2 marks. Forcing insertion without proper alignment may cause the pins to bend and break.

Electrical parameters

Connecting device: Cable sealing joint

Power supply: 24 V DC ± 10%, ≥0.3A (for a single positioner).

Ambient temperature: 0~70°C

Protection level: IP66

Anti-vibration parameter: 100Hz

Inspection Issues

1. The display screen does not light up after the locator is powered on

Ensure the DC24V power supply is connected, and check if the positive and negative poles are properly connected.

2. The locator is unable to locate the opening and closing of the valve for an extended period of time

3. Check whether the air pressure meets the cylinder pressure requirements, whether there is any leakage in the air supply pipe, and whether there is any leakage in the cylinder.

4. Precautions for connecting to the gas source:

A filter regulator must be installed before connecting the air source to the positioner.

The operating pressure of the air source should not exceed O.7 MPa and should be less than 0.3 MPa; otherwise, the cylinder cannot be opened.

Interface description

The positioner includes four touch buttons. Users can operate the relevant functions of the positioner through these four buttons. The display screen will show numerical indications to display the percentage range of the effective travel of the displacement sensor or the percentage range of the valve travel.
