GE DS200ACNAGIACC Mark VIe Digital Input/Output Module
Product Overview
The GE DS200ACNAGIACC is a high-performance Digital Input/Output (DI/DO) Module designed for GE’s Mark VIe distributed control system (DCS), serving as a critical interface between industrial control systems and field devices. Engineered to manage discrete signals (e.g., switches, relays, and actuators), this module enables real-time monitoring and control in mission-critical applications across power generation, oil & gas, and manufacturing sectors. As part of the DS200 Series, the DS200ACNAGIACC ensures reliable signal transmission and fault-free operation in harsh industrial environments, where precision and durability are non-negotiable.
Featuring a robust design, the GE DS200ACNAGIACC supports multiple digital input/output channels with galvanic isolation, protecting the control system from voltage surges and electromagnetic interference (EMI). Its hot-swappable architecture allows for module replacement without powering down the system, minimizing downtime during maintenance. The module’s compatibility with GE’s Proficy software suite enables seamless configuration, diagnostics, and integration with higher-level SCADA systems, enhancing operational efficiency and reducing engineering complexity.
In automation ecosystems, the DS200ACNAGIACC acts as a bridge between the Mark VIe controller and field devices, converting binary signals (e.g., ON/OFF states) into digital data for processing and sending control commands to actuators. Its dual-channel design supports redundant operation, ensuring system resilience in critical applications such as turbine trip systems, emergency shutdown (ESD) logic, and conveyor control. By delivering reliable discrete signal management, this module optimizes process safety, reduces unplanned outages, and extends the lifecycle of industrial equipment.

Key Features and Advantages
Dual-Functionality Design: The DS200ACNAGIACC integrates both digital input and output channels, simplifying system architecture by combining signal acquisition and control in a single module. This dual functionality reduces hardware complexity and cabling requirements, lowering installation and maintenance costs.
Galvanic Isolation and Noise Immunity: Each channel features 500 V RMS galvanic isolation, preventing ground loops and protecting the control system from transient voltage spikes. Advanced filtering ensures reliable signal integrity in high-noise environments, such as those with motor drives or power transformers.
Hot-Swap Capability: The module’s plug-and-play design allows for safe replacement while the system is operational, enabling maintenance without disrupting ongoing processes. This feature is critical for 24/7 industrial operations where downtime must be minimized.
Redundant Signal Processing: With dual-channel redundancy, the DS200ACNAGIACC ensures continuous operation even if one channel fails. This design meets the highest reliability standards, making it suitable for safety instrumented systems (SIS) compliant with IEC 61508 and IEC 61511.
Wide Operating Range: Built to withstand extreme temperatures, vibration, and humidity, the module complies with industrial standards (e.g., IEC 60068-2-6 for vibration), ensuring performance in harsh environments like offshore platforms, refineries, and power plant control rooms.
User-Friendly Configuration: Compatible with GE’s Proficy software, the module allows engineers to configure input/output states, set debounce timers, and monitor channel health via a intuitive interface. Real-time diagnostics provide instant feedback on signal status, reducing troubleshooting time.
Application Areas
The GE DS200ACNAGIACC is widely deployed in industries requiring reliable discrete signal control and monitoring:
- Power Generation: Manages turbine trip signals, generator breaker states, and auxiliary system controls in thermal, hydro, and nuclear power plants. For example, it interfaces with emergency stop switches to trigger shutdowns during critical faults.
- Oil & Gas: Controls valve positions, pump starters, and safety interlocks in refineries, pipelines, and offshore platforms. It supports ESD systems by monitoring pressure switches and activating shutdown sequences when thresholds are exceeded.
- Manufacturing: Optimizes production lines by controlling conveyor belts, robotic arms, and packaging machinery. The module’s fast switching speed (≤10 ms) ensures precise coordination in high-speed assembly processes.
- Water/Wastewater Treatment: Monitors level switches and flow meters, sending commands to pumps and valves to maintain optimal process conditions. Its rugged design withstands moisture and corrosive environments in treatment facilities.
Specific applications include:
