Safety Redundancy Architecture：GE IS420UCSCS2A supports triple-mode redundancy (TMR) design, achieving fault tolerance through three independent relay groups，The main trip relay (PTR1/PTR2) works with the emergency trip relay (ETR) to ensure high system reliability.

Core Safety Functions：Perform key safety operations such as electrical/mechanical overspeed trip test and TMR cross trip test，Built-in fault detection logic, automatically triggering shutdown protection when two relay groups are abnormal.

Auxiliary Control Output：Provides 4 auxiliary control interfaces, including electrical locking solenoid valves, oil reset solenoid valves, GE IS420UCSCS2A to support complex control logic

Industrial Communication Interface：Supports IONet network protocol, seamlessly integrated with Mark series I/O modules，Optional EGD protocol, compatible with data interaction of non-safety systems Supports online updates, and control logic adjustments can be completed without downtime.

Thermal power generation and steam turbine control：GE IS420UCSCS2A Used in the main protection system of steam turbines, monitoring parameters such as speed, temperature, pressure, and executing emergency shutdown commands

Gas turbine safety system：Integrated in the gas turbine control unit to achieve fuel control, ignition logic and SIL 2/3 safety level protection

Industrial process safety control：Deployed in high-risk industries such as chemical industry, oil and gas, and ensure interlocking protection of key equipment through redundant architecture

Wind power control system：GE IS420UCSCS2A May be adapted to offshore wind turbines, participating in cabin control or grid protection
