    Motorola MVME715P 6U VME Isolated Digital I/O Transition Module (IndustryPack IP Carrier Slave Board)
    Manufacturer: Motorola Computer Group, later Emerson Artesyn
    Model: MVME715P (P = panel-mounted transition I/O version)
    Series Position: Standard digital I/O transition matching board for MVME162 / MVME5100 / MVME5500 VME SBCs, dedicated DCS field signal expansion card
    Type: Single-height 6U VMEbus slave-only module, A16/D16 addressing, IndustryPack IP mezzanine carrier with isolated DI/DO channels
    Core Function: Isolated field digital signal acquisition & relay output expansion for petrochemical/thermal power Honeywell TDC3000 LCN racks; interrupt-driven/DMA high-speed I/O transfer, channel isolation, overcurrent self-protection, full on-board diagnostic LEDs; compatible with VxWorks OS for Motorola VME platform
    1. Product Overview
    MVME715P is a dedicated VME digital I/O transition slave board serving as IndustryPack IP carrier, exclusively matched with Motorola’s mainstream VME single board computers (legacy MC68K MVME162 series and later PowerPC MVME5100/MVME5500). It cannot operate independently and must be controlled by host SBC via VMEbus. The board integrates 32-channel isolated digital input and 32-channel isolated digital output, with full channel-to-channel galvanic isolation to eliminate industrial ground loop interference. It provides front-panel DB25 external wiring terminals for field 24VDC sensor/valve connection, and dedicated VME P2 rear connector to link with SBC’s IndustryPack expansion slot. All DI/DO circuits adopt self-resetting polyfuse overcurrent protection, reverse polarity input protection and ESD surge suppression, adapting to harsh DCS cabinet environments. It supports interrupt triggering on signal edge change and DMA block transmission to reduce host CPU I/O load, widely deployed for valve status feedback, switch interlock, alarm signal collection and on-site actuator driving in Honeywell TDC3000 distributed control systems. P suffix stands for panel transition version, with complete front panel signal interface, separate from rear-transition MVME715 model.

    3. MVME715P vs MVME715 Difference
    1. MVME715P: P = Panel transition, all field signal wiring via front panel DB25 connectors, convenient on-site maintenance
    2. MVME715: Rear transition version, all I/O routed through VME P2 rear connector, no front field wiring terminals, for fully sealed cabinet deployment
    3. Core DI/DO circuit, isolation standard, VME bus logic are identical between two variants
    4. Core Application Scenarios
    • Honeywell TDC3000 DCS LCN rack field digital signal expansion: valve feedback, interlock switch, alarm DI, actuator control DO
    • Thermal power plant boiler/turbine VME control cabinet digital logic signal acquisition & output
    • Petrochemical refining distributed control system isolated field I/O expansion
    • Aerospace ATE test bench digital switching signal acquisition board
    • Railway signal cabinet isolated interlock digital I/O module
