Product Introduction
The Woodward 1751-6058 is a specialized 4-channel Magnetic Pick-Up (MPU) transformer module engineered to interface speed sensors with turbine control systems, engine management governors, and heavy industrial monitoring architecture.
In heavy-duty power generation, gas/steam turbine, and large diesel engine applications, MPU sensors monitor rotational speed by tracking flywheel or gear teeth passing. The 1751-6058 module provides necessary electrical isolation and signal conditioning across four independent channels, protecting downstream control cards from high-voltage transients, electrical noise, and ground loops.

Compliance & Standards Alignment
- Manufactured in accordance with rigorous Woodward quality control specifications, ISO standards, and industrial turbine management safety rules.
- Engineered to provide high common-mode noise rejection and galvanic isolation, protecting sensitive speed-governing control processors from electrical disturbances.
Technical Note: Because MPU inputs are critical for overspeed trip protection and governing loops on rotating machinery, always verify wiring polarity and channel designations against your turbine control schematic to prevent phase cancellation or erroneous speed reads.
Storage & Asset Preservation Guidelines
- Store the module inside its original packaging or an antistatic environment to protect internal transformer windings and terminal blocks from dust, moisture, and corrosion.
- Maintain a clean, dry, climate-controlled warehouse setting with relative humidity kept under 85% (non-condensing).
- Avoid mechanical heavy shocks, drops, or physical stress on the barrier strip terminal connections.
Physical Installation Prerequisites
- Ensure that all local control panel power rails, engine safety circuits, and MPU sensor loops are completely de-energized, isolated, and locked out (LOTO) prior to installation or wiring.
- Verify proper wire termination torque on all screw terminals to prevent intermittent speed signals caused by high-vibration industrial environments.
- Keep MPU signal wiring shielded and routed separately from high-voltage power lines or motor variable-frequency drive cables to minimize electromagnetic induction.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this Woodward transformer module?
A: Electrical transformers, static converters, and specialized industrial signal conditioning parts typically classify under HS code 8504.31 (Electrical transformers, having a power handling capacity not exceeding 1 kVA) or 8538.90. Confirm final codes with your customs broker.
Q: Does the 1751-6058 require external power to operate?
A: As a passive multi-channel isolation transformer module, it typically conditions and passes analog MPU signals directly through magnetic coupling without requiring active DC supply power, though system architecture varies by application. Check your specific control loop drawing.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market availability, factory lead times, and surplus tier conditions; contact our technical sales desk for a formal, time-sensitive quotation.
