IS220YPROS1A  Functional Description    

The IS220YPROS1A GE Backup Protection I/O Module is a critical backup protection module designed for GE's Mark VIe Speedtronic turbine control systems. This robust I/O module operates on 24VDC (±10%) with a maximum power consumption of 15W, featuring 1500VAC isolation between field and logic circuits. The Mark VIeS Backup Turbine Protection I/O Pack GE IS220YPROS1A  provides precise analog input capabilities with 16-bit resolution and ±0.1% accuracy, supporting both 0-250mV and ±10V ranges through software configuration. Its compact 8.2×13×6cm design weighs just 0.36kg, making it ideal for space-constrained installations.

Manufactured in the USA and distributed globally through Xiamen, China, the IS220YPROS1A Speedtronic Turbine Controller General Electric is built for extreme environments, operating reliably in -40°C to +70°C temperatures and 5-95% humidity. The module's conformal-coated PCB ensures durability in harsh industrial conditions, while its 5VDC backplane can deliver up to 1.2A for connected peripherals. Available in both unused and rebuilt conditions, the IS220YPROS1A General Electric I/O Module ships same-day for urgent replacement needs.

Key features include dual Ethernet ports for redundant network connectivity, diagnostic LEDs for real-time status monitoring, and soft-start circuitry to prevent inrush current damage. The module's DC-37 pin connector ensures secure integration with Mark VIe terminal boards, while its UL listing and CE certification guarantee compliance with international safety standards.

As part of GE's Speedtronic series, the Protection I/O Pack IS220YPROS1A delivers critical backup protection for gas and steam turbines, combining advanced diagnostics with fail-safe operation. Its robust design and precise measurement capabilities make it essential for power generation facilities requiring reliable turbine protection systems.
