2. Product Features
- High Integration: The analog front-end, A/D conversion, gain/offset adjustment, DMA control, and digital I/O are all implemented on the same board, reducing wiring and system latency.
- Modular Design: Compliant with the VME-64 standard, it can be directly inserted into any VME-bus backplane, facilitating system expansion and maintenance.
- Flexible Input Configuration: The voltage range and gain can be quickly switched via jumpers or software to meet the needs of different sensors.
- High-Speed Sampling: With a maximum sampling rate of 50 kHz, it is suitable for high-speed signal monitoring.
- Reliable Industrial-Grade Performance: Features a wide operating temperature range, anti-interference design, and compliance with VME-bus electrical specifications.
3. Structure and Composition
- Analog Front-End: Includes input buffers, programmable gain amplifiers (PGA), and offset adjustment circuits.
- A/D Converter: 12-bit (or optional higher resolution) sample-and-hold circuit.
- Digital Logic: Consists of a DMA controller, register mapping, and VME interrupt control.
- Jumper Area: Used to select the voltage range, gain, and input mode (single-ended/differential).
- Power Management: Provides voltage regulation, filtering, and overcurrent/overvoltage protection.
- Connectors: Standard VME-64 slot and analog signal terminal block (screw terminals or pins).
4. Typical Application Fields
| Industry | Application Scenario |
|---|---|
| Process Control | Analog acquisition of sensors for temperature, pressure, flow, liquid level, etc. |
| Industrial Automation | Front-end acquisition module for PLC and DCS systems |
| Experimental Testing | Multi-channel signal acquisition for laboratory instruments |
| Energy Management | Data acquisition from monitoring points in power plants and distribution networks |
| Aerospace | Multi-channel analog signal input for ground test platforms |
| Automotive Manufacturing | Data acquisition and monitoring of production line sensors |
5. Installation and Maintenance Points
Installation
- Insert the card into a backplane slot compliant with the VME-64 standard, ensuring the 卡扣 (clips) on the back of the card are securely fastened.
- Check that the power supply meets the specifications (+5 V, +12 V) and confirm the normal power distribution of the backplane.
- Set the corresponding input range and gain via jumpers or software according to the on-site sensor voltage range.
Wiring
- Use screw terminals or pin terminals to connect sensor signals, paying attention to the polarity (for single-ended) or positive-negative pairs (for differential).
- For differential inputs, ensure the signal lines are symmetrical and well-shielded to reduce noise.
Debugging
- After power-on, check whether the VME-bus interrupt vector is correctly mapped.
- Read the registers through the host computer software to verify that the sampling value of each channel is within the expected range.
Daily Maintenance
- Regularly check the tightness of the terminal block to prevent signal distortion caused by loosening.
- Remove dust from the surface of the card and keep the heat sink well-ventilated.
- In case of abnormal interrupts or sampling errors, first check the power supply, jumper configuration, and integrity of the signal lines, then consider replacing the A/D chip or the entire card.
