Deskripsi
Control Module
• Type: Intelligent actuator control module
• Model: STZ
• Brand: Changzhou Power Plant Auxiliary Equipment Factory Co., Ltd.
Product Overview:
The STZ Module is a specialized control board used in intelligent electric actuator systems, particularly for valve regulation, signal processing, and motor control. It integrates analog and digital logic to manage actuator behavior based on input signals, feedback, and protection parameters. STZ modules are typically embedded in TP400 or SND-series actuator assemblies.
Specifications (typical for STZ modules):
| Feature | Specification |
|---|---|
| Input Signal | 4–20 mA analog or digital control |
| Output Signal | Relay logic or PWM motor control |
| Feedback Input | Potentiometer (1 kΩ) 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 Functions | Over-torque, over-travel, phase loss, signal loss |
| Communication | RS-485 / Modbus RTU (optional) |
| Operating Temp | −25 °C to +70 °C |
| Humidity | ≤95% RH (non-condensing) |
| Mounting | Panel or actuator enclosure mount |
| PCB Material | FR4 industrial-grade |
