Description
GE DS215UDSAG1AZZ01A: High-Performance Digital Signal Conditioning Module
Product Overview
The GE DS215UDSAG1AZZ01A is a digital signal conditioning module engineered for GE’s Speedtronic Mark V gas turbine control system. As a key component of the Mark V platform, this module processes and conditions digital signals from field devices, ensuring reliable data transmission between sensors, actuators, and the central control unit in industrial power generation, oil & gas, and marine propulsion applications. Designed to withstand harsh operating environments, the DS215UDSAG1AZZ01A features the rugged durability and precision engineering synonymous with GE’s industrial automation solutions.
Featuring a modular VME rack-mount design, the DS215UDSAG1AZZ01A integrates seamlessly with Mark V control systems, supporting hot-swappable installation for maintenance without system downtime. It serves as a bridge between digital input/output signals (e.g., from proximity probes, limit switches, or solenoid valves) and the control processor, converting raw signals into standardized formats for real-time analysis. The module’s 16-channel digital input capability and 8-channel relay output configuration make it ideal for complex control loops requiring high-density signal management .
Built with GE’s proprietary signal conditioning technology, the DS215UDSAG1AZZ01A includes built-in surge protection and noise filtering to minimize interference in electromagnetic-rich environments. Its EEPROM firmware enables field-upgradable functionality, while diagnostic LEDs (green for power, red for faults) provide real-time health monitoring. Backward compatible with legacy Mark V systems, this module offers a cost-effective path for modernizing aging infrastructure without replacing entire control architectures.

Key Features and Advantages
High-Density Signal Management: With 16 digital input channels and 8 relay outputs, the DS215UDSAG1AZZ01A consolidates multiple field signals into a single module, reducing cabling complexity and rack space requirements. This density is particularly valuable in large turbine control systems with numerous sensors and actuators .
Rugged Industrial Design: The module’s aluminum alloy casing and conformal coating protect against dust, moisture, and vibration, ensuring reliable performance in harsh environments like offshore platforms, refineries, and power plants. Its wide temperature range (-20°C to +60°C) further enhances adaptability .
Real-Time Diagnostics: Built-in LED indicators and self-test (BIST) features continuously monitor channel health, voltage levels, and communication integrity. Fault codes are transmitted to the central control system, enabling proactive maintenance and minimizing downtime .
Hot-Swap Capability: The module supports live replacement without powering down the system, a critical feature for maintaining continuous operation in mission-critical applications. This reduces maintenance time and costs associated with scheduled outages .
Flexible Configuration: Jumpers and dip switches allow field technicians to customize input/output parameters (e.g., signal filtering, debounce time, relay activation thresholds) to match specific application requirements, eliminating the need for custom hardware .
Applications
The GE DS215UDSAG1AZZ01A is ideal for industrial environments requiring precise digital signal conditioning:
- Power Generation: Managing digital signals from turbine speed sensors, fuel valve position indicators, and emergency shutdown systems in gas and steam power plants.
- Oil & Gas: Processing signals from pressure switches, flow meters, and safety interlocks in offshore platforms, pipeline compressor stations, and refineries.
- Marine Propulsion: Conditioning signals from propulsion system sensors (e.g., shaft position, bearing temperature) and controlling actuators for fuel injection and pitch adjustment.
- Industrial Manufacturing: Coordinating digital I/O for turbine-driven machinery in chemical plants, steel mills, and large-scale manufacturing facilities.
- Renewable Energy: Interfacing with control signals in combined heat and power (CHP) plants, ensuring seamless integration of renewable energy sources with traditional turbine systems.

Installation and Maintenance
Installation Preparation:
Ensure the Mark V VME rack is properly grounded and powered off. Align the DS215UDSAG1AZZ01A with the rack slot and secure it using captive screws. Connect 24V DC power to the designated terminals, ensuring correct polarity. Terminate field signal cables to the 20-pin connectors, separating power and signal wiring to minimize EMI. Perform a visual inspection to confirm all jumpers and switches match the application configuration.
