VMIC VMIACC-BT03 Rear Transition Panel

Module Feature

VMIACC-BT03 is a single-slot 6U VMEbus passive rear transition panel developed by VMIC (GE Fanuc / Abaco Systems),belonging to BT0X transition panel family. It mates with VMIVME-1184,VMIVME-344X and VMIVME-345X front VME I/O boards. This rear panel adopts dual 96-pin male connectors and bussed ground barrier terminal strips with lift-clamp terminals,accepts wire gauge 12–22 AWG. Fully passive hardware without any active semiconductor chips,only PCB trace routing for discrete digital and event sequence signals. Bussed ground plane optimizes common-mode noise suppression and simplifies shield wiring connection. It complies with ANSI/IEEE SWC TEST specification,fits standard EIA RS-310C 19-inch VME rack. Rugged Eurocard PCB with conformal coating,shock and vibration screened for power plant cabinet environment,widely used in gas/steam turbine sequence-of-event signal wiring,aerospace ground test bench and hardware-in-loop real-time simulation VME chassis.

Working principle

Discrete I/O and event signals from front VME I/O module pass through VME backplane to dual 96-pin connectors of VMIACC-BT03. Internal PCB traces route all signals to rear lift-clamp barrier terminals. Bussed ground plane unifies signal shielding reference. No power consumption and no signal processing,only pure passive wiring transition.

Onboard components

VME rear panel ejector hardware,dual 96-pin male connectors,bussed-ground lift-clamp barrier terminal block,passive copper trace network and continuous ground shield plane.

LED indicators

No LED indicators,completely passive hardware.

Hardware self-diagnosis

Visual inspection of PCB,components and solder joints;continuity test for all signal lines;96-pin connector pin contact test;shield and bussed ground continuity verification.

Programming software

No driver or software required,completely passive transition hardware.
