GE IS420UCSCH2A Dual-Core Mark VIe Controller

GE IS420UCSCH2A (UCSC) is a core controller assembly for GE’s Mark VIe Speedtronic control platform, designed for gas/steam turbine control, compressor management, 

and heavy industrial automation. It features a dual-core processor, QNX Neutrino real-time OS, and extensive I/O/networking for mission-critical applications.

Processor & OS: Dual-core architecture, QNX Neutrino RTOS for deterministic real-time performance

Memory: Onboard flash/RAM for application code, configuration, and data logging; supports external storage expansion

Communication: Multiple Ethernet ports (RJ45), UDH/IONet connectivity, Modbus, and industrial fieldbus support for system integration

I/O Capability: Integrates with Mark VIe I/O modules (digital/analog I/O, RTD, thermocouple, relay) for distributed control

Redundancy: Supports redundant controller configurations for high availability in critical processes

Environmental: -40°C to +85°C operating range, 95% non-condensing humidity, convection cooling, industrial EMC compliance

Power: Backplane-powered (5V DC), max consumption ~40W, reverse polarity and surge protection

Applications: Gas/steam turbine control, power generation, oil & gas, petrochemical, and heavy industrial process automation
