Technical Specifications: Input Signal Type: VME bus differential signal, internal board communication signal Input Voltage Range: +5 VDC bus power supply Input Impedance: Standard VME bus impedance value Input Current: Typical operating current, maximum limited current Response Time: ≤1 µs Channel‑to‑Backplane Isolation Voltage: 500V RMS Transient Surge Suppression: 1500V Operating Power Supply: +5VDC Communication Protocol: VME64 backplane bus protocol Operating Temperature: 0 °C to +60 °C Storage Temperature: -50 °C to +85 °C Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Standard 6U single‑slot module for VME rack Certifications: CE, UL, industrial EMC standard compliance
Functional Features: Supports high‑speed VME bus data transmission and system logic processing. Provides hardware filtering to suppress industrial electromagnetic interference. Implements hardware‑based fault detection for system fault tolerance. Built‑in comprehensive self‑diagnosis for channel status, power supply and internal circuit. 
Performance Parameters: Maximum VME bus throughput: 40 MB/s Processing capacity: Equipped with 2G onboard memory Fault tolerance: Single‑peripheral fault will not interrupt module overall function Mean Time Between Failures.
Structural Characteristics: Standard 6U single‑slot plug‑in structure matching VME standard rack. Front panel with status indicator LED lamps for power, channel fault and communication. Front panel fixing screws for board locking.
Working Principle: Internal system bus signals enter through VME golden‑finger connectors. Hardware filter circuits eliminate high‑frequency interference signals. Isolation circuits complete electrical isolation between backplane bus and local board logic circuit.
Installation Requirements: Install the module into designated slot of standard 6U VME rack. Ensure rack ground connection strictly follows system grounding specification. Separate power cable and signal cable routing inside cabinet to avoid crosstalk.
Usage Notes: Do not apply supply voltage exceeding rated value to module power pins. Keep cabinet internal dust accumulation under control to avoid golden‑finger contact failure. Perform regular inspection for front‑panel LED status indicators.
