Technical Specifications Condition New/Never Used Surplus Brand General Electric Category Turbine Control Systems Part Number IC3600LIBA1A Subcategory Input Buffer Card Series Mark I / Mark II Product Type Input Buffer Card Edge Connector 26 metal pins Mounting Features Two factory-drilled corner holes Board Identification GE logo and code 68A989162G1 Application Input signal buffering and conditioning System Compatibility Speedtronic Mark I and Mark II Information About IC3600LIBA1A The IC3600LIBA1A is an input buffer card manufactured by General Electric for the Mark I and Mark II Speedtronic turbine control platforms. It is designed to receive field input signals and buffer them to maintain signal integrity before processing by downstream control circuitry. The board interfaces with the Speedtronic system through a 26-pin edge connector and is mechanically secured using factory-drilled mounting points. It remains in service within long-standing turbine installations where early Speedtronic systems continue to operate reliably. Key Features Input signal buffering: Stabilizes incoming signals to protect control logic from noise and distortion. Mark I and Mark II compatibility: Engineered specifically for early GE Speedtronic turbine systems. High-integrity signal handling: Supports accurate and reliable processing of multiple input sources. Compact PCB design: Includes edge-pin connectivity for efficient system integration. Durable industrial construction: Built to withstand long-term operation in turbine environments. Legacy system support: Enables continued operation of widely deployed Mark I and Mark II platforms. GE-manufactured reliability: Designed and produced to original General Electric specifications. The IC3600LIBA1A delivers the reliability and precision required for stable input signal buffering in GE Mark I and Mark II Speedtronic gas and steam turbine control systems.
