General Electric IS420UCSBH1A Controller Module

GE IS420UCSBH1A is a UCSB controller module specially developed by General Electric (GE) for Mark VIe control system. UCSB controller is a computer that runs specific application control logic independently. It does not carry application I/O itself, but relies on the connected I/O network to obtain data input. This design ensures the robustness of system performance and can minimize downtime during maintenance. Even if the controller is powered off, data can continue to flow.

Fuctions & Features

• Pre-installed Software: The GE IS420UCSBH1A controller comes pre-installed with application-specific software that is capable of executing control logic via ladder or block. Minor changes to the control software can be made online without restarting the system.

• IEEE 1588 Protocol: The GE IS420UCSBH1A uses the IEEE 1588 protocol to synchronize the I/O packages and the controller's clock to within 100 microseconds, ensuring precise coordination and time synchronization throughout the control system.

• Data Transfer: External data is transferred between the control system database and I/O modules of the GE IS420UCSBH1A controller via R, S, and T IONets.

• Dual System Support: In a dual-controller setup, the GE IS420UCSBH1A controller can synchronize internal state values, initialization information, and synchronization data between the two controllers.

• Triple Modular Redundancy (TMR) System: In a TMR system, the GE IS420UCSBH1A module supports data synchronization and state values ​​for voting and redundancy across three controllers.
