Product Introduction
The IS220UCSAH1A is a high-performance embedded controller module designed for the Mark VIe distributed control system (DCS) family. It serves as a central processing or “brain” module, executing control logic, supervising I/O networks, and coordinating automation tasks in demanding industrial applications.
It is engineered for real-time response and reliability, using a robust micro-processor, passive cooling (fan-less), multiple network ports, and rugged design for industrial and turbine control environments. The module supports redundant configurations and integration with multiple I/O packs, providing flexibility and longevity in system architectures.
This controller is typically placed within the I/O rack architecture of a control system, and communicates with other modules via high-speed Ethernet connections. It enables complex tasks such as equipment protection, process automation, turbine load control, and network management. Its design emphasises maintainability, scalability and serviceability in industrial automation installations.
