GE DS200NATOG2A Mark VIe Digital Input Module
Product Overview
The GE DS200NATOG2A is a high-reliability Digital Input Module designed for GE’s Mark VIe distributed control system (DCS), serving as a critical component in industrial automation and machinery protection applications. Engineered to monitor discrete signals from field devices such as switches, relays, and safety interlocks, this module converts binary inputs into digital data for processing by the Mark VIe controller. As part of the DS200 Series, the DS200NATOG2A ensures precise and noise-free signal acquisition in harsh environments, making it indispensable for power generation, oil & gas, and manufacturing sectors where reliable monitoring of equipment status is essential for operational safety and efficiency.
Featuring a rugged industrial design, the GE DS200NATOG2A supports up to 16 isolated digital input channels, each capable of detecting voltage levels ranging from 24 V DC to 125 V AC. Its advanced signal conditioning includes galvanic isolation (250 V RMS) and anti-bounce filtering, minimizing interference from electromagnetic sources and ensuring accurate detection of transient or steady-state signals. The module’s compatibility with GE’s Proficy software suite enables real-time status monitoring, alarm configuration, and diagnostic feedback, enhancing system visibility and reducing maintenance downtime.
In automation ecosystems, the DS200NATOG2A acts as the interface between field-level discrete devices and the Mark VIe control platform, facilitating seamless integration with other modules such as analog input/output (AI/AO) and communication gateways. Its hot-swappable design allows for module replacement without disrupting system operation, ensuring continuous monitoring during maintenance. By delivering reliable digital data for logic control and safety interlocks, this module supports critical applications like turbine shutdown systems, conveyor control, and process safety management, making it a cornerstone of GE’s Mark VIe distributed control architecture.

Key Features and Advantages
High-Reliability Signal Acquisition: The DS200NATOG2A ensures accurate detection of discrete signals with configurable debounce times, preventing false triggers from electrical noise or mechanical vibration. Galvanic isolation on each channel eliminates ground loops, enhancing signal integrity in high-interference environments such as power plants or manufacturing floors.
Redundant and Hot-Swappable Design: Built with a rugged metal enclosure, the module supports hot swapping, allowing maintenance personnel to replace faulty units without powering down the system. This feature minimizes downtime in 24/7 operations, while redundant power paths ensure continuous operation during transient power fluctuations.
Flexible System Integration: Compatible with a wide range of voltage levels, the DS200NATOG2A adapts to diverse field devices, reducing the need for multiple module types. Its integration with GE’s Proficy software enables easy configuration of input parameters, alarm thresholds, and diagnostic reports, streamlining system setup and maintenance.
Industrial-Grade Durability: Designed to withstand extreme temperatures, vibration, and humidity, the module meets rigorous standards (e.g., IEC 61131-2), making it suitable for harsh environments like offshore platforms, refineries, and mining sites. Its conformal-coated circuitry protects against dust, moisture, and corrosive elements, ensuring long-term reliability.
Scalable I/O Expansion: As part of the Mark VIe ecosystem, the DS200NATOG2A can be paired with other DS200 Series modules (e.g., analog outputs, communication gateways) to build scalable control systems. This flexibility allows for easy expansion of I/O capacity as process requirements evolve, reducing upfront and upgrade costs.

Installation and Maintenance
Pre-installation Preparations:
Before installing the GE DS200NATOG2A, ensure the Mark VIe rack is properly grounded and ventilated. Verify that the module’s voltage settings match the connected field devices (e.g., 24 V DC for proximity sensors, 125 V AC for industrial switches). Use shielded cables to connect discrete inputs to the module’s terminal blocks, routing cables separately from high-power conductors to minimize electromagnetic interference. Configure the module in GE’s Proficy software, assigning channel addresses and enabling debounce filtering as needed for each input.
