VMIC 333-012210-000 A Transition I/O Board

Module Feature

333-012210-000 A is a single-slot 6U VMEbus passive rear transition I/O board developed by VMIC,used together with corresponding front VME I/O boards. It routes analog/digital signals from VME P2 rear connector to external terminal blocks or multi-pin field connectors. This is a passive board without active chips,only copper trace routing for signal transfer, no signal amplification or conversion. It supports quick field wiring and reduces front panel cable clutter in VME rack. Compatible with multiple VMIC analog input,analog output and digital I/O series boards. Rugged Eurocard PCB with conformal coating,shock and vibration screened for power plant cabinet environment,widely used in gas/steam turbine VME control cabinet wiring,aerospace ground test bench and industrial VME chassis rear signal distribution.

Working principle

P2 backplane pins of front VME module connect through VME rear backplane to P2 connector on this transition board. Internal PCB traces directly route all signals to external field connectors. No power consumption and no signal processing,only physical signal path extension.

Onboard components

P2 rear VME connector,multi-pin field I/O terminal connector,passive copper trace network,VME J1/J2 edge connector.

LED indicators

No LED indicators.

Hardware self-diagnosis

Visual inspection of PCB,components and solder joints;continuity test for each signal channel;P2 pin connection verification.

Programming software

No driver or software required,fully passive hardware.
