Regulating Control Board
• Type: Analog regulating control board
• Model: ZBZC
• Brand: Changzhou Power Plant Auxiliary Equipment Factory Co., Ltd.
Product Overview:
The ZBZC Regulating Control Board is a specialized PCB designed for electric actuator systems that require continuous or proportional valve regulation. Unlike simple open/close logic boards, ZBZC supports analog input signals (typically 4–20 mA) and provides smooth motor control based on feedback and setpoint comparison. It’s commonly used in flow control, pressure regulation, and process automation.
Specifications (typical for ZBZC boards):
| Feature | Specification |
|---|---|
| Input Signal | 4–20 mA analog (standard) |
| Input Resistance | 250 Ω |
| Output Signal | 4–20 mA (isolated), or PWM/motor control logic |
| Feedback Input | Potentiometer (1 kΩ typical) or encoder |
| Control Accuracy | ±1% basic error |
| Dead Zone | Adjustable 0–3% |
| Travel Adjustment | Zero point ±10%, range 35%–110% |
| Power Supply | 24 VDC or 220 VAC (model-dependent) |
| Protection | Over-torque, over-travel, signal loss |
| Communication | Optional RS-485 / Modbus RTU |
| Operating Temp | −25 °C to +70 °C |
| Humidity | ≤95% RH (non-condensing) |
