Product Details:

The GE IS220PPROH1A, part number 336A4940CSP19, is a high-reliability Protection I/O Pack Module developed for GE Speedtronic Mark VIe distributed turbine control systems. This industrial control spare part delivers independent hardware overspeed and turbine trip protection, acting as a safety backup unit separate from the main controller. As a reliable Turbine Control Module, it adopts 32-bit RISC processor, equipped with 16MB SDRAM and 32MB Flash memory, executing fast protection logic to trigger turbine trip action when abnormal overspeed occurs. It is designed for critical safety protection of gas turbines and steam turbines.

The GE IS220PPROH1A Protection I/O Pack Module is equipped with dual 100Mbps IONet Ethernet ports for redundant network communication, ensuring stable data exchange between the protection pack and system controller. It supports simplex, dual and TMR redundant system configurations and allows hot replacement without full system shutdown. Front panel LED indicators display power status, communication link and protection channel faults in real time. The module has built-in comprehensive self-diagnostic functions to detect circuit faults and sensor abnormalities. Conformal coated circuit board resists vibration, dust and moisture in harsh power plant environments. It is widely used in power generation and oil & gas compressor stations for turbine safety control system maintenance, spare part replacement and system upgrade.
