IS220UCSAH1AK | GE Electric Universal Controller Safety Module
Product Description
The GE IS220UCSAH1AK is a critical Universal Controller Safety Module from the Mark VIeS Safety Series, designed for high-integrity control and monitoring in industrial safety systems. It executes safety-critical functions (SIL 2/SIL 3 certified) for gas/steam turbine protection, ensuring fail-safe shutdown during hazardous conditions. Key roles include logic processing, I/O interfacing, and real-time diagnostics for power generation and process industries.
Key Features
- Safety Integrity: TÜV-certified SIL 2/3 compliance (IEC 61508).
- Redundant Architecture: Dual-processor redundancy for fault tolerance.
- I/O Integration: Interfaces with analog/digital safety signals (e.g., speed sensors, pressure switches).
- Communications: Dual 100 Mbps Ethernet ports (TCP/UDP) for Mark VIe network integration.
- Diagnostics: Continuous self-monitoring with fault logging and event sequencing.
- Robust Design: Operates in extreme environments (-40°C to +70°C).

Series Overview
Part of the GE Mark VIeS Safety System, the UCSAH series provides certified safety control for critical machinery. The IS220UCSAH1AK variant includes:
- IS220: Mark VIeS series identifier.
- UCSA: Universal Controller Safety Application.
- H1: Hardware revision (high-temperature tolerance).
- A: Standard configuration.
- K: International packaging/shipping version.
Applications
- Power Generation: Turbine overspeed protection, flame detection, emergency shutdown (ESD).
- Oil & Gas: Safety instrumented systems (SIS) for compressors/pumps.
- Industrial Processes: Burner management, reactor shutdowns.
- Marine: Critical propulsion control.
Functional Role
The IS220UCSAH1AK processes safety logic to initiate shutdowns when predefined hazards (e.g., overpressure, overspeed) are detected. It validates sensor data, executes voting logic, and communicates trip commands to actuators while recording event sequences for forensic analysis.
Why Choose the IS220UCSAH1AK?
- Lifecycle Safety: Reduces risk of catastrophic failures in SIL 3 applications.
- Seamless Integration: Compatible with Mark VIe control ecosystems.
- Cyber Security: Supports industrial security protocols (IEEE 1686).
- Global Compliance: Meets IEC 61508, ISO 13849, and API 670 standards.
