VMIC 332-003413-111 C VME Signal Processing Board

Module Feature

VMIC 332-003413-111 C is a single-slot 6U VMEbus rugged signal processing board developed by VMIC,built for harsh industrial,defense and aerospace test environments. It conforms to standard VMEbus electrical and mechanical specifications,compatible with standard VME chassis and other VMIC VME modules. VME bus interface supports A16/A24 addressing and D08/D16/D32 data transfer,works as VME slave. The board adopts reinforced PCB with conformal coating,resists vibration and mechanical shock,wide operating temperature range. Integrated built-in BIT diagnostic circuit monitors power supply and internal circuit health,latches fault status for software readback. Onboard overvoltage,reverse polarity and ESD protection safeguard hardware from field surge interference. Widely deployed in gas/steam turbine auxiliary signal conditioning,aerospace ground test benches and industrial distributed VME control chassis.

Working principle

VME host sends configuration and data commands through VME backplane. Onboard logic circuit completes signal conditioning,conversion and processing for field I/O signals. BIT circuit runs periodic self-check to capture abnormal power and circuit faults. VME FPGA implements address decoding and bidirectional data handshake between VME bus and signal processing core. Protection circuits cut off abnormal voltage to prevent permanent hardware damage.
