GE DS2020UCOCNIG1A: Universal Communication Interface Module for Mark VIe Turbine Control Systems
Product Overview
The GE DS2020UCOCNIG1A is a universal communication interface module designed for GE’s Speedtronic Mark VIe gas turbine control system. As a critical component of the Mark VIe platform, this module enables seamless integration between the central control processor and field devices, supporting real-time data exchange, protocol translation, and system diagnostics in industrial power generation, oil & gas, and marine propulsion applications. Engineered with GE’s advanced signal conditioning technology, the DS2020UCOCNIG1A ensures reliable communication in harsh environments, making it ideal for mission-critical systems requiring high availability.
Featuring a modular VME rack-mount design, the DS2020UCOCNIG1A integrates seamlessly with other Mark VIe components, such as the DS2020UCSAG1A control processor and DS2020UPLAG1BZZ01A power supply. Its multi-protocol support (including SRTP, EGD, and Modbus TCP/IP) allows it to interface with a wide range of sensors, actuators, and third-party devices, reducing the need for dedicated communication gateways . The module’s 16-channel universal I/O capability (supporting analog, digital, and relay signals) further enhances flexibility, making it suitable for complex control loops requiring high-density signal management.
Built with rugged aluminum casing and conformal coating, the DS2020UCOCNIG1A withstands extreme temperatures (-20°C to +60°C), humidity, and vibration, ensuring reliable performance in offshore platforms, refineries, and power plants. Its field-upgradable firmware and configurable jumpers enable technicians to adapt the module to specific applications, such as turbine speed control or emergency shutdown systems, without hardware modifications.

Key Features and Advantages
Multi-Protocol Flexibility: The DS2020UCOCNIG1A supports SRTP, EGD, Modbus TCP/IP, and Profibus DP, allowing it to interface with GE’s proprietary systems and third-party devices. This versatility reduces dependency on multiple communication modules, simplifying system architecture .
High-Density Signal Management: With 8 analog inputs, 8 digital I/O, and 4 relay outputs, the module consolidates diverse signal types into a single unit, minimizing cabling complexity and rack space. This is particularly valuable in large turbine systems with numerous sensors and actuators .
Rugged Industrial Design: The module’s corrosion-resistant casing and conformal coating protect against harsh conditions, while its wide temperature range (-20°C to +60°C) ensures reliability in offshore platforms, power plants, and marine environments. Vibration resistance (5 g, 10–2000 Hz) further enhances durability in high-stress applications .
Real-Time Diagnostics: Built-in LED indicators (power, channel health, fault) and self-test (BIST) features enable proactive maintenance. Fault codes are transmitted to the central control system, minimizing downtime by identifying issues like open circuits or voltage anomalies .
Hot-Swap Capability: The module supports live replacement without system shutdown, a critical feature for maintaining continuous operation in mission-critical setups. This reduces maintenance time and costs associated with scheduled outages .
Applications
The GE DS2020UCOCNIG1A excels in industrial scenarios requiring versatile communication interfaces:
- Power Generation: Managing analog signals from turbine speed sensors and digital signals from emergency shutdown systems in gas/steam power plants.
- Oil & Gas: Processing pressure/temperature sensor data and controlling valve actuators in offshore platforms, refineries, and pipeline compressor stations.
- Marine Propulsion: Conditioning shaft position signals and managing fuel injection relays for marine gas turbines, enabling real-time adjustments to propulsion systems.
- Industrial Manufacturing: Coordinating I/O for turbine-driven machinery in chemical plants, steel mills, and large-scale production facilities.
- Renewable Energy: Interfacing with hybrid power systems, such as combining gas turbines with solar/wind generators for stable grid integration.

Installation and Maintenance
Installation Preparation:
Ensure the Mark VIe VME rack is grounded and powered off. Align the DS2020UCOCNIG1A with the rack slot, secure it with captive screws, and connect 115–230 V AC power (verify polarity). Terminate field cables to the 20-pin connectors, separating power and signal wiring to minimize EMI. Configure jumpers and dip switches per the application (e.g., analog input range, relay activation mode).
