C.1 standard, supporting 32-bit/64-bit data transmission modeBus Bandwidth: Up to 80MB/s, meeting high-speed data interaction requirementsBridging Chip: Integrated UNIVERSE CA91C142 VME-PCI bridging chip, with 33MHz clock rateArbitration Level: Built-in 4-level VMEbus arbiter, supporting master/slave device mode switchingInterface Configuration: 1 VME bus interface (P1/J1 standard connector), 2 RS-485 serial interfaces, 1 10/100Mbps Ethernet interfacePower Supply Voltage: 220V ACOutput Frequency: 50kHzInterrupt Support: VMEbus interrupts can be assigned to any of the 7 interrupt request linesStatus Indication: Red LED indicates VMEbus interrupt request; yellow LED indicates VMEbus access status
Environmental Parameters
Operating Temperature: -40℃ to +70℃ (non-condensing environment)Storage Temperature: -55℃ to +85℃Relative Humidity: 5% to 95% (non-condensing)EMC Compliance: Conforms to industrial electromagnetic interference protection standards, adapting to complex industrial electromagnetic environmentsProtection Rating: IP20 (module itself, requiring VME chassis for overall protection)
Mechanical Parameters
Overall Dimensions: Conforming to 6U VME board standard size, compatible with single slot of standard VMEbus chassisHousing Material: Flame-retardant engineering plastic (UL94 V-0 grade) with RFI shielding functionMounting Method: Standard VMEbus slot mounting, connected to backplane via 160-pin VG connectorExpansion Capability: Supports installation of 2 single-width or 1 double-width PMC modules; supports cascading expansion of up to 16 VME slave modulesFront Panel Configuration: Equipped with knockout for PMC module front panel and status indicator window
Product Performance
Data transmission efficiency is high: 80MB/s maximum bus bandwidth combined with 33MHz bridging chip realizes bottleneck-free interaction between VME and PCI buses; multi-device collaborative response time is shortened to less than 10ms, meeting real-time processing needs of large-scale data.
Expansion adaptability is flexible: Supports access of all commercial PMC modules and cascading of 16 VME slave modules; can flexibly configure data acquisition, communication expansion and other functions, enabling system upgrade without reconstruction.
System compatibility is strong: Complies with VMEbus and PMC related international specifications, can be seamlessly integrated into GE Fanuc VME series industrial computers and DCS systems, supporting real-time operating systems such as Unix and VxWorks.
Operation reliability is outstanding: Low-power design reduces heat dissipation requirements, adapting to environments without forced air cooling; comprehensive LED status indicators can real-time feed back device operation status, facilitating quick fault location.
Environmental adaptability is excellent: The wide temperature range of -40℃ to +70℃ covers high and low temperature industrial scenarios; anti-electromagnetic interference design ensures stable operation in environments with dense high-power equipment without signal distortion or communication interruption.
