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 multi‑channel VME bus high‑speed data transmission and signal conversion. Provides hardware filtering to suppress industrial electromagnetic interference. Implements hardware redundant design for communication channel fault tolerance. Built‑in comprehensive self‑diagnosis for channel status, power supply and internal circuit. 
Application Scenarios: VM600 turbine machinery protection system. Large rotating equipment condition monitoring rack. Petrochemical plant machinery safety monitoring. Power plant turb‑generator unit protection system. Industrial VME rack safety interlock control loops.
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. Backplane golden finger interface for VME system bus connection.
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. Processing units capture bus data signals, execute data packet forwarding and routing.
Installation Requirements: Install the module into designated slot of standard 6U VME rack. Separate power cable and signal cable routing inside cabinet to avoid crosstalk. Board replacement operation must comply with site power‑off safety operation procedure.
