- Power Distribution Module: Internal wiring enables multi-channel voltage output, including 5 V, 12 V, –5 V, –12 V, etc.
- Connectors: Include power, signal, and cooling fan interfaces at the front and rear ends.
5. Application Fields
- Industrial Automation Control: PLC, motion control, and robot control systems.
- Data Acquisition and Monitoring: Fieldbus gateways, sensor arrays, and process monitoring.
- Test and Measurement Instruments: High-speed data acquisition cards and signal analyzers.
- Military and Aerospace: Embedded systems requiring high-reliability VME-bus architecture.
6. Installation and Maintenance Points
Installation
- Fix the main board in a chassis that meets VME-bus specifications, ensuring the screws are tightly fastened.
- Connect power cables (for 5 V, 12 V, etc.) according to the power wiring diagram, and check the polarity.
- Insert functional modules (e.g., CPU, I/O cards) and ensure the card latches are fully closed.
Debugging
- Before power-on, use a multimeter to check if the power distribution is normal.
- After power-on, confirm the integrity of signals in each slot through Power-On Self-Test (POST).
Maintenance
- Regularly check the dust and oxidation status of the backplane slots, and clean them with an anti-static brush if necessary.
- If a module malfunctions, first eliminate poor card contact, then replace the corresponding VME-bus card.
- Record the replaced components and test results for each maintenance to facilitate traceability.
