Product Description

The Woodward ProTech 203 Overspeed Protection System offers a range of digital overspeed trip devices. These devices utilize three identical speed-sensing units configured for two-out-of-three hardware voting. Model 8200-211 is a de-energize-to-trip version with an input voltage of 220 Vac.

The 8200-211 system has several safeguards against overall device failure and system downtime.

  • A built-in frequency generator allows for the prime mover to remain online while speed-sensing units are tested one at a time
  • In the event of a single unit trip, normal operations are maintained by the other two units
  • A single unit can be replaced without disrupting operations
  • The two-out-three vote is based on three separate speed calculations
  • Each speed-sensing unit has its own set of functional status LED indicators

This ProTech 8200-211 system has a speed-sensing frequency range of 100 Hz to 32 kHz and a trip-point frequency range of 250 Hz to 25 kHz. It has an accuracy rating of

±(0.05% x Trip Point in Hz +2 Hz).

All three speed-sensing units are in the same key locked enclosure, preventing unauthorized access to programming and testing capabilities. Each unit has its own front panel complete with a touchpad and two-line LCD display, which can be used to view the actual current speed of the individual unit.

If overspeed conditions are met and a unit trips, a separate LED and alarm output will alert of the condition. When this occurs, if the current speed is above the previously recorded peak speed, the system’s peak speed is updated and stored in non-volatile memory. This continues even after a unit is tripped.

Additional Woodward model 8200-211 information can be found in ProTech 203 Manual 85206 (F).
