VMIC 332-004512-300 Analog Input Transition Board

Module Feature

332-004512-300 is a single-slot 6U VMEbus passive rear transition I/O board developed by VMIC (GE Fanuc / Abaco Systems). It mates with matched front-side analog input VME acquisition modules,transfers multi-channel analog signals from VME P2 rear connector to rear shielded terminal block connectors. This board is fully passive without active semiconductor chips,only PCB copper trace routing for analog signal transmission,without signal amplification,conversion or data processing. It moves all field analog cable connections to the rear side of VME chassis,reducing front panel cable congestion and minimizing analog signal interference with optimized ground and shielding layout. The terminal block supports differential analog wiring for noise suppression. Rugged Eurocard PCB with conformal coating,shock and vibration screened for power plant cabinet environment,widely used in gas/steam turbine analog signal acquisition cabinet wiring,aerospace ground test bench and legacy VME chassis rear signal distribution.

Working principle

P2 pins of front analog input VME module connect through VME backplane to P2 connector of this transition board. Internal shielded PCB traces directly route all incoming analog differential signals to rear terminal block connectors. No power consumption required; it only provides physical signal path extension and analog wiring transition.

Onboard components

VME J1/J2 edge connector,P2 rear VME connector,shielded analog terminal block,passive copper trace network and grounding shield plane.

LED indicators

No LED indicators,completely passive hardware.

Hardware self-diagnosis

Visual inspection of PCB,components and solder joints;continuity test of each analog signal channel;P2 pin contact and shield ground continuity verification.

Programming software

No driver or software required,completely passive hardware.
