GE IS420YAICS1B – Industrial Control Processor Board
The GE IS420YAICS1B processor board serves as the core component in gas/steam turbine control systems, particularly within GE’s Mark VIe automation framework. This high-performance module excels in real-time data processing and control signal generation, ensuring precise regulation of critical industrial processes in power generation and heavy manufacturing environments.
Technical Specifications
- Processing Power: High-performance industrial processor
- Power Consumption: 5.3 Watts (typical)
- Environmental Range: -40°F to 158°F operating temperature
- ADC Resolution: 16-bit analog-to-digital conversion
- Physical Dimensions: 3.25″H × 1.65″W × 4.78″D
- Software Compatibility: ControlST Suite v6.01+ / Firmware v5.01+


Application Context
In gas turbine power plants, this processor board manages combustion control sequences and vibration monitoring systems. Its 16-bit ADC ensures accurate fuel flow regulation, while the front panel LEDs provide instant diagnostics for field engineers. We’ve deployed this module in both new installations and retrofit projects across:
- GE Frame 7FA turbine control systems
- Mark VIe steam turbine governor applications
- Combined cycle power plant automation upgrades
The IS420YAICS1B works seamlessly with complementary GE modules like the IS220PPDAH1B communications board and VMIVME-7807 I/O interface cards.
