GE IS220PPROH1A IO CARD MKVIE
Product Description:
The GE IS220PPROH1A is a Backup Turbine Protection (PPRO) I/O Pack designed for GE’s industrial control systems, primarily Mark Series architectures. As a critical safety component, it delivers an independent backup overspeed protection system, generator synchronization checks, and a watchdog function for primary controls—safeguarding turbines in emergency scenarios. It operates in either triple modular redundant setups or simplex configurations, connecting to emergency trip boards (TREG, TREL, TRES, TREA) via DC-37 pin cables. Equipped with Ethernet for IONet communication, it streamlines field device integration while boosting reliability and cutting maintenance costs.
Key Features:
Backup Protection Functions: Provides independent overspeed backup, generator sync checks, and primary control watchdog, ensuring turbine safety during primary system failures. Hardware-implemented overspeed monitoring and speed signal tracking enhance responsiveness.
Redundancy & Compatibility: Supports TMR and simplex setups, compatible with Mark VIe trip boards. Uses BPPB processor boards; functionally aligns with BPPC-equipped PPROS1B. Note: No auto-reconfiguration when swapping BPPB/BPPC P-Packs.
Hardware & Connectivity: Features a high-speed processor, dual independent 10/100 Ethernet ports, hardware watchdog, and internal temp sensor. Field-wiring limits: 1,000ft of 18 AWG for voltage sensing; connects to barrier/box-type terminal blocks. Runs on a power supply with built-in protection.
Diagnostics & Design: Front faceplate displays component ID, paired LEDs for status monitoring, and an IR port for low-level diagnostics. Conformal PCB coating and A-rated revision ensure durability; modular “IS220” design eases installation on TREAH_A terminal boards.
Industrial Resilience: Tailored for aeroderivative turbine emergency trips, reducing external instrumentation needs. Operates reliably in harsh industrial environments, with design focus on long-term performance and minimal downtime.
