IS220PPROH1A

About the IS220PPROH1A

• The IS220PPROH1A is a Turbine specific I/O module designed by GE.
• Its purpose is to provide a direct interface to specific turbine field devices.
• This design reduces the need for external instrumentation, improves running reliability, and reduces long-term maintenance.

Hardware Tips and Specifications

• Typically works with the TREAH_A terminal board.
• Used in Aeroderivative Turbine Emergency trip applications.
• Can connect to either barrier or box-type terminal blocks.
• Field wiring restrictions for voltage sensing: Limits cable length to 1,000 feet of 18 AWG wiring.
• Important Note: Cannot be auto-reconfigured when swapping a BPPB P-Pack with a BPPC P-Pack.
• Built with a front faceplate displaying:
  • Component ID number.
  • Several LED indicators, placed in pairs:
    • PWR/ATTN
    • LINK/TxRx and ENET 1
    • LINK/TxRx and ENET2
  • Three speed signals: deceleration, acceleration, overspeed.
  • Hardware-implemented overspeed.
• Functional Product Number (IS220PPROH1A) provides hardware specifications:
  • IS220 series tag: Identifies special modular Mark VI Series assembly version and domestic original manufacture location.
  • PPRO: Functional acronym.
  • H1: Conformal PCB coating and group one Mark VI Series product grouping.
  • A: A-rated functional product revision.
