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 functionWeight: Approximately 0.5kgMounting Method: Standard VMEbus slot mounting, connected to backplane via two 160-pin VG connectorsExpansion Interfaces: Two single-width PMC slots, compatible with one double-width PMC module installationFront Panel Configuration: Includes knockout for PMC module front panel and status indicator window

Product Performance

Expansion compatibility is strong: It supports access of all commercial PMC modules, and can flexibly configure functional modules such as data acquisition, communication expansion and motion control, enabling system function upgrade without additional adaptation components.

Data transmission is efficient: 33MHz bus clock rate combined with VME-PCI bridging technology realizes bottleneck-free data interaction between VME and PCI buses, meeting the high-speed transmission requirements of industrial control commands and monitoring data.

System integration is convenient: Directly compatible with GE Fanuc VME series industrial computers and DCS systems, supporting VMEbus master/slave mode switching, and enabling rapid application deployment through dedicated drivers provided by manufacturers.

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 interrupt and bus access status, facilitating quick location of abnormalities.

Environmental adaptability is excellent: The wide temperature range of -40℃ to +85℃ 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.
