FAQ

• What does "SRLY" stand for?
  It stands for "Relay," indicating this board is part of the relay interface and protection circuitry within the turbine control system.
• What is the purpose of the conformal coating?
  It provides a protective barrier against humidity, chemical vapors, dust, and fungal growth, ensuring long-term reliability in industrial power generation environments.
• Can a blown fuse be replaced?
  Yes, the 3.15A Littelfuse fuses are user-replaceable. Always replace with an identical specification fuse (Littelfuse 04773.15MXP or equivalent) after isolating power.
