Core Product Overview

• Model: IS200SPROH1ADD
• Base Part: IS200SPROH1A; suffix ADD means full factory acrylic conformal coating for harsh oil-mist, high-humidity turbine cabinet environments
• Series: GE Speedtronic Mark VI / Mark VIe Turbine Control Platform (SPRO = Secondary Protection Terminal Board)
• Hardware Type: Passive rack-mounted signal conditioning & termination PCB, exclusive mating terminal board for the IS220PPROH1A hardware overspeed safety I/O pack
• Core Functions:
  1. Condition raw AC magnetic speed probe / Keyphasor signals for PPRO overspeed safety processing
  2. Integrates dual built-in Potential Transformers (PTs) to acquire generator & bus voltage analog inputs
  3. Provides pluggable field wiring terminals for all protection sensors and trip interlock circuits
  4. Routes conditioned signals to PPRO I/O pack via multi-pin internal ribbon connectors
  5. Equipped with DC-37 pin expansion port to connect downstream backup trip relay terminal boards
• Typical Application: Gas/steam turbine, generator and refinery compressor triple modular redundant (TMR) safety protection racks, independent hardware overspeed, overvoltage and emergency shutdown (ESD) interlock signal termination.
