Original GE UCSA standalone controller for Mark VIe Speedtronic turbine control system, fan‑less embedded CPU spare part.

Product Overview

IS220UCSAH1A is UCSA standalone controller for GE Speedtronic Mark VIe turbine control system. Equipped with 667MHz Freescale PowerQUICC II Pro processor and QNX Neutrino real‑time operating system, it executes turbine speed regulation, load control, interlock and protection logic. It communicates with remote I/O packs via redundant IONet Ethernet, stores firmware and application programs on CompactFlash card. Supports simplex, dual and TMR triple‑modular‑redundant deployment. Fan‑less passive cooling design, conformal‑coated hardware fits power‑plant cabinet continuous operation. Widely used as maintenance spare part for gas turbine, steam turbine and generator control systems.

Key Features

• 667 MHz Freescale PowerQUICC II Pro embedded processor for deterministic real‑time control logic
• Multiple 10/100Mbps Ethernet ports, supports redundant IONet I/O network and UDH supervisory network
• CompactFlash storage slot for firmware, application configuration and fault event log storage
• Supports simplex, dual hot‑standby and TMR triple‑modular‑redundant system configuration
• Fan‑less passive cooling structure, no fan failure risk for long‑term cabinet operation
• Front‑panel multi‑color LED indicators for power, running status and fault diagnosis

• Panel‑mount box‑type structure, allows adjacent stacking for triple redundant unit layout
