The **PV10-R01** is a high-precision, motorized proportional pressure regulator (typically manufactured by companies like **CKD**). It is an electro-pneumatic device that converts an electrical signal into a proportional pneumatic pressure output. Below is the detailed breakdown of its electronic components and specifications. --- ### 1. Core Electronic Specifications The PV10-R01 relies on a closed-loop control system to maintain pressure accuracy. | Component / Feature | Specification Details | | :--- | :--- | | **Supply Voltage** | 24V DC (Standard range: 12V to 24V DC) | | **Input Signal** | 0 to 10V DC (Voltage type) or 4 to 20mA (Current type) | | **Power Consumption** | Approximately 4W or less during operation | | **Output Monitor** | 1 to 5V DC (Analog feedback signal) | | **Control Method** | PWM (Pulse Width Modulation) for solenoid driving | --- ### 2. Key Electronic Parts & Functions #### A. Internal Pressure Sensor (Transducer) The "heart" of the electronic side is a silicon-based semiconductor pressure sensor. * **Function:** It constantly monitors the output pressure at the secondary port. * **Feedback Loop:** It sends a voltage signal back to the internal comparator to ensure the actual pressure matches the input signal command. #### B. Solenoid Valve Drivers The unit contains two miniature high-speed solenoid valves: 1. **Supply Valve:** Opens to increase pressure. 2. **Exhaust Valve:** Opens to vent pressure to the atmosphere. * These are controlled via **PWM signals** from the CPU to allow for fine increments of air movement. #### C. Control Circuit (PCB) The internal Printed Circuit Board manages the logic: * **A/D Converter:** Converts your analog input signal (e.g., 0-10V) into digital data. * **PID Controller:** A microprocessor-based controller that calculates the error between the desired pressure and actual pressure. * **D/A Converter:** Converts the feedback from the internal sensor into an analog monitor signal for the user. --- ### 3. Wiring Configuration The device typically uses a standard M12 or multi-pin lead wire. The pinout generally follows this logic: | Pin Number | Wire Color | Function | | :--- | :--- | :--- | | 1 | Brown | Power Supply (+24V DC) | | 2 | White | Input Signal (+) (0-10V / 4-20mA) | | 3 | Blue | Common (0V / GND) | | 4 | Black | Monitor Output (Feedback) | --- ### 4. Operational Logic 1. **Input:** You send a 5V signal to the PV10-R01. 2. **Logic:** The electronic board interprets this as 50% of the maximum pressure range (e.g., 0.5 MPa if the range is 1.0 MPa). 3. **Action:** The board activates the **Supply Solenoid**. 4. **Feedback:** The **Internal Sensor** detects the rise. Once it hits exactly 0.5 MPa, the board closes the solenoid. 5. **Monitor:** The unit outputs a specific voltage (e.g., 3V) on the monitor wire to tell your PLC that the pressure is reached.
