Overview
The GE IS400UCLIH1A is a high-performance Application Control Layer (UCLI) module designed for GE’s Mark VIe and Mark VIeS control systems. It serves as the central processing unit for executing real-time control logic, managing I/O communications, and coordinating system-wide data exchange. This module is engineered for mission-critical applications in power generation, oil and gas, and industrial automation.
Built for reliability and scalability, the IS400UCLIH1A supports redundant configurations and integrates seamlessly with Ethernet-based IONet and Unit Data Highway (UDH) networks. Its robust architecture ensures deterministic performance, even under high-load conditions. Moreover, the module is housed in a Universal Control Panel (UCP), offering easy installation and maintenance in field environments.
In addition, the UCLI module supports advanced diagnostics, secure firmware, and time-synchronized control, making it ideal for turbine control, balance-of-plant coordination, and safety instrumented functions. Its proven track record in demanding environments reinforces its role as a trusted component in GE’s automation ecosystem.
