FUNCTIONAL DESCRIPTION:

8271-485 is a Two-Channel Digital Speed Switch manufactured and designed by Woodward as part of the 8200 Series used in Turbine Control Systems. Woodward's ESSE Series comprises single-channel (ESSE-1) or two-channel (ESSE-2) electronic speed switches, offering exceptional power transient protection. These units are encapsulated for robust defense against harsh environmental conditions, demonstrating both reliability and durability while remaining flexible and cost-effective. In generator set applications, the ESSE Series proves versatile, serving purposes such as crank (starter motor) disconnect, overspeed protection, as well as under speed and overspeed warnings. Virtually all speed-related switching functions on diesel and gas engines, along with other rotating machinery, can be effectively managed by ESSE speed switches.

FEATURES:

• The control package offers full authority speed setting in either a 4–20 mA or 1–5 Vdc range.
• It provides a choice between isochronous or droop speed control.
• Both low- and high-voltage models are available, and the control package includes a signal converter.
• Users can make high and low-speed adjustments, and the system incorporates a start fuel limit with an override feature.
