IS220UCSAH1A | GE Electric Security level universal controller
Product Description
The GE IS220UCSAH1A is a Safety Rated Universal Controller from the Mark VIeS series, designed for critical protection systems in industrial automation. It performs high-integrity safety functions (SIL 3 certified) for gas/steam turbines, compressors, and rotating equipment by executing real-time logic, processing I/O signals, and triggering fail-safe shutdowns during hazardous conditions.
Key Features
- Safety Compliance: TÜV-certified SIL 3 (IEC 61508/61511).
- Triple Modular Redundancy (TMR): Three 32-bit processors with 2-out-of-3 voting logic.
- Integrated I/O: Interfaces with safety-rated analog/digital modules (e.g., overspeed detection, pressure/temperature).
- High-Speed Networking: Dual 100 Mbps Ethernet ports for Mark VIe control network integration.
- Advanced Diagnostics: Continuous self-tests, event sequencing (SOE), and predictive fault alerts.
- Extreme Environment Operation: -40°C to +70°C temperature range.

Series Overview
Part of GE’s Mark VIeS Safety Platform, the IS220UCSAH1A belongs to the UCSA safety controller family:
- IS220: Mark VIeS hardware series.
- UCSA: Universal Controller Safety Application.
- H1: Hardware revision (industrial-grade components).
- A: Standard SIL 3 configuration.
Applications
- Power Generation: Turbine overspeed protection, flame detection, burner management.
- Oil & Gas: Emergency shutdown (ESD) systems for pipelines/compressors.
- Chemical Plants: Safety interlocks for reactors/pressure vessels.
- Marine & Heavy Industry: Critical machinery shutdowns.
Functional Role
- Signal Processing: Reads inputs from safety sensors (vibration, temperature, pressure).
- Logic Execution: Runs preconfigured safety logic (e.g., “trip turbine if speed > 110%”).
- Failsafe Action: Triggers shutdown outputs (relays, actuators) within milliseconds.
- Data Logging: Records event sequences with 1 ms resolution for forensic analysis.
Why Choose IS220UCSAH1A?
- Zero Single-Point Failures: TMR architecture eliminates critical faults.
- Seamless Integration: Native compatibility with Mark VIe I/O and Proficy HMI/SCADA.
- Cybersecurity: Supports TLS 1.2 encryption and role-based access (IEC 62443).
- Lifecycle Management: 20-year+ support with firmware backward compatibility.
