Functional Features: Local PID position loop on onboard DSP, auto-reconfiguration via ToolboxST, watchdog disable on comms loss, ENA1/ENA2 per-channel enable, front LED set (PWR, ENet1/2, ATTN, ENA1/2).
Application Scenarios: Gas turbine liquid/gas fuel valve, steam turbine governor valve, compressor IGV, combined-cycle bypass valve.
Material Composition: FR4 multilayer PCB, industrial DSP, gold-plated backplane contacts, polycarbonate front window.
Structural Characteristics: VME-style pack body, dual RJ45 front, 24 V terminal via TSVO board.
Working Principle: Receives setpoint over IONet → DSP compares LVDT feedback → drives ±10 V to WSVO → hydraulic servo valve moves → position re-sampled.
Installation Requirements: Insert into Mark VIe I/O rack, seat TSVO terminal board, torque field wires to spec.
Usage Notes: Do not hot-insert with 24 V applied to TSVO; match firmware to Mark VIe project revision.
