1. Product Overview
The GE IS220PAICH2A (336A4940CSP11) is a high-performance analog input/output (I/O) pack (PAIC) designed for GE Speedtronic Mark VIe turbine control systems, serving as a critical interface for analog signal acquisition and control in gas, steam, and aeroderivative turbine applications. It integrates a BPPx processor board and dedicated analog acquisition hardware, supporting 10 configurable analog inputs (voltage/current) and 2 flexible analog outputs (0-20mA/0-200mA). With dual 100Mbps full-duplex Ethernet ports for I/O network connectivity, DC-37 pin terminal board interface, and compatibility with simplex/dual/triple modular redundant (TMR) systems, the module delivers precise, real-time signal processing for pressure, temperature, flow, and position sensors in power generation, oil & gas, and industrial turbine installations. Its rugged design (-40°C to +70°C operating range) and compliance with industrial standards (UL 508, IEC 61326-1) ensure reliable performance in 24/7 critical control environments.
