8237-1246 FAQ

How should engineers identify 8237-1246 before approving a replacement?

Match part number 8237-1246, hardware revision, bulkhead enclosure, HV/LV inputs, voted relays and the installed turbine trip-system record.

Which documented family contains 8237-1246?

Woodward lists 8237-1246 in the ProTech-GII triple-modular-redundant overspeed protection family.

What is the documented configuration?

The official model table identifies bulkhead mounting, HV/LV power inputs and voted relays.

What power inputs are documented?

The HV/LV configuration uses one 90-240 Vac / 100-150 Vdc input and one 18-32 Vdc input. Verify both installed circuits.

What trip-output architecture applies?

The voted-relay configuration uses two dual-redundant trip outputs in a 2-out-of-3 voted architecture.

Which speed sensors are supported?

The ProTech-GII monitors turbine speed and acceleration through active or passive magnetic pickups. Confirm the installed sensor type and signal range.

Can another ProTech-GII part number be used automatically?

No. Mounting, power inputs, relay architecture, revision and conversion eligibility must all be confirmed from Woodward documentation.

What environmental review applies?

Woodward documents an IP56-based environment for the bulkhead enclosure. Final suitability depends on the complete enclosure and installation.

What should a sourcing request include?

Provide 8237-1246, revision, quantity, destination, nameplate images, power configuration, sensor type and trip-system wiring. Stella can coordinate the review.

What manufacturer-data boundary applies?

Only facts traceable to Woodward Product Specification 03370, Manual 26545 and PCN 06912 are used. Site-specific trip settings require approved turbine documentation.
