I. Product Brief Introduction
This control board is used for differential pressure measurement and DC solenoid valve drive control, suitable for high-temperature scenarios. Equipped with 3 pressure measurement channels and 3 solenoid valve drive channels, it fully ensures the backup use of multiple channels. Key parameters of downhole working environment conditions, such as pressure, operating temperature, and solenoid valve drive current, can be monitored in real-time.II. Functional Parameters
| Parameter Item | Specifications |
| Pressure Measurement | 3 channels, externally connected to 4-wire pressure sensors |
| Solenoid Valve Driv | 3 channels, capable of driving DC solenoid valves within 5A. The measurement accuracy of drive current is higher than 0.1mA, with overcurrent protection, shutdown and restart functions to effectively protect solenoid valves from damage. |
| Upper Computer Display | Information such as pressure, voltage, temperature and current can be displayed in graphical and numerical forms. Solenoid valves can be controlled via upper computer software commands, with frequency and duty cycle configurable. Historical data is stored as files, and historical faults during solenoid valve drive control can be automatically filtered out. |
| Operating Temperature | -40℃ ~ +150℃ |
| Power Supply | ±15V |
| Total Power Consumption | Less than 1.5W |
| Communication Method | CAN Bus |
| Dimensions | 32mm * 200mm |
