Official facts for engineering and procurement
PRODUCT DESCRIPTIONOverspeed protection deviceDesigned to safely shut down steam, gas and hydro turbines, motors, compressors and reciprocating engines after an overspeed or over-acceleration event.
EXACT VARIANTBulkhead HV/LVWoodward Manual 26545 lists 8237-1246 as the bulkhead-mount model with high-/low-voltage power configuration and voted trip relays.
ARCHITECTUREThree independent modulesTriple modular redundant design with 2-out-of-3 voting logic supports safety and availability in critical rotating-equipment applications.
SPEED PERFORMANCE0.5 to 32,000 rpmThe official manual specifies a 12 ms response time for the ProTech-GII product family.
INPUTS & OUTPUTSMPU or PROXOne speed input per module, three alarm-relay outputs total and three analog speed outputs total.
LIFECYCLE NOTENon-preferred modelWoodward identifies 8237-1596 as the preferred part number for this configuration; conversion, replacement and compatibility require separate confirmation.

Power and system data for the exact HV/LV variant
| Item | Official data | Procurement relevance |
|---|---|---|
| High-voltage input | 90-264 Vac / 47-63 Hz or 100-150 Vdc | 30 W per module; verify the plant supply and branch protection. |
| Low-voltage input | 18-32 Vdc, nominal 24 Vdc | 30 W per module; the model combines one HV and one LV input per module. |
| Trip arrangement | 2oo3 voted relays | Match the complete 8237-1246 configuration; do not infer relay behavior from another ProTech-GII part number. |
| Environmental | IP56 · 95% RH non-condensing · 3000 m altitude | Confirm mounting location, ventilation, shock and vibration conditions. |
| Standards statement | IEC 61508 SIL-3; designed to meet API-670, API-612 and API-611 | System integration and proof-test requirements remain application-specific. |

Selection questions that affect the project
What distinguishes 8237-1246 from nearby ProTech-GII part numbers?Woodward lists it as the bulkhead-mount, HV/LV model with voted trip relays. Mounting, both power inputs and relay arrangement must all match.
What should be checked when considering the preferred model 8237-1596?Woodward names 8237-1596 as the preferred number for the same configuration, but revision, software, field wiring, configuration files and the official conversion path must be reviewed separately.
Which speed sensor types are supported?The official manual states that each of the three modules accepts one speed input using an MPU or a proximity probe. Confirm sensor type, signal range, gear data and wiring before commissioning.
