FAQ

• What is the function of a PDIA pack?
  It serves as the main I/O processor module, handling communication between the turbine controller (CPU) and the field signal conditioning terminal boards.
• Can this module be used in explosive atmospheres?
  Yes, it carries UL certifications that allow installation in designated hazardous (classified) areas when installed per guidelines.
• What is the difference between this and a terminal board?
  This is an active electronic module. Terminal boards (e.g., IS200STCIH1A) are passive boards that provide screw terminals and signal conditioning components; the PDIA pack drives them.
