Product Overview

1751‑6058 is multi‑channel MPU signal isolation transformer module for Woodward speed‑governor systems. It receives raw AC pulse signals from magnetic‑pickup speed sensors on turbines and engines, provides galvanic isolation and signal conditioning, sends conditioned speed‑feedback signals to governor controller for rotational‑speed measurement and closed‑loop speed‑control. Used for gas‑turbine, steam‑turbine and large diesel‑generator control cabinets. Surplus and refurbished tested spare MPU signal‑processing module for power‑generation turbine‑control‑system maintenance projects.

Application Notes

‑ Verify MPU sensor wiring polarity before power‑on. ‑ Check signal amplitude at module input terminals during commissioning. ‑ Observe ESD precautions when handling internal circuit boards. ‑ Typical deployment: Turbine governor MPU transformer module spare‑part stocking.
