GE IS420UCSBH1A UCSB Controller Module

Product Description

The GE IS420UCSBH1A is a high-performance UCSB Controller Module for the Mark VIe control system, engineered for reliable turbine operation. It executes complex control logic independently and communicates seamlessly with I/O modules via the IONet protocol. Moreover, its IEEE 1588-based synchronization ensures precise timing across all connected components, maintaining optimal performance in both gas and steam turbine applications. Designed without a fan, this compact module operates efficiently in harsh industrial environments, reducing maintenance and improving overall system uptime.

In addition, the controller features robust onboard memory and an Intel EP80579 600 MHz processor, enabling real-time execution of control algorithms. Its durable design supports wide temperature ranges, ensuring stable operation from –40 °C to +85 °C. The module also offers standard Ethernet connections for external monitoring and Modbus communication, making integration with existing SCADA systems straightforward.
