Functional Description
The GE IS220PPROH1A interfaces directly with turbine field devices, reducing instrumentation needs and improving reliability. It works with the TREAH_A terminal board and is commonly used in emergency trip applications for aeroderivative turbines. The module supports wiring lengths up to 1,000 feet with 18 AWG cable for voltage sensing.
It features three speed signal inputs—deceleration, acceleration, and overspeed—alongside hardware-based overspeed protection. The front faceplate includes LED indicators for PWR/ATTN, LINK/TxRx, and ENET ports. Equipped with a high-speed processor, dual 10/100 Ethernet ports, and internal temperature monitoring, the IS220PPROH1A ensures robust turbine protection. Notably, it does not support auto-reconfiguration when swapping P-Pack types and is identified by its A-rated functional revision.
Applications and Compatibility
The IS220PPROH1A is essential for turbine protection in GE’s Mark VI Series, supporting gas, steam, and wind turbine systems. It enhances durability, reduces maintenance, and ensures safe operation in critical industrial environments. Its compatibility with EX2100 architectures makes it a reliable choice for power generation and heavy automation sectors.
