Technical Specifications

I/O Channel Details

Function Features

• Universal Signal Compatibility: 16 individually configurable channels support thermocouple, RTD, voltage, current (4-20 mA input/0-20 mA output), pulse accumulator, and digital input signals, reducing hardware footprint and simplifying system design.
• Independent Channel Commissioning: Independently wireable terminal sections enable channel-by-channel debugging and commissioning, minimizing downtime during installation and maintenance.
• Hot-Swap Capability: Supports hot-swappable replacement without system shutdown, ensuring continuous operation and reducing maintenance time.
• Auto-Reconfiguration: Automatically reconfigures channel settings upon replacement, eliminating manual reconfiguration and ensuring system consistency.
• Deterministic IONet Integration: Integrates with Mark VIe IONet architecture for low-latency (sub-1 ms) data transmission, supporting real-time control applications.
• High Measurement Accuracy: Better than 0.1% accuracy across all signal types within the operating temperature range, ensuring precise control and monitoring.
• Harsh Environment Design: Conformal-coated PCB and wide operating temperature range (-40°C to +70°C) protect against moisture, dust, and vibration in industrial settings.
• Front-Panel Diagnostics: LEDs for power, IONet communication, channel status, and faults enable quick troubleshooting without software tools.
• ControlST Compatibility: Works with ControlST V07.02.00C or later for intuitive configuration, monitoring, and diagnostics.
• Overvoltage/Short-Circuit Protection: Each channel includes overvoltage and short-circuit protection, preventing damage from signal transients and wiring errors.
• Compact Form Factor: Backplane-mounted design saves space in control cabinets, supporting high-density I/O configurations.

Application Scenarios

• Gas Turbine Control: Acquires and controls temperature, pressure, speed, and vibration signals in aeroderivative/heavy-duty gas turbines, enabling precise fuel flow and combustion control.
• Steam Turbine Control: Monitors steam temperature, pressure, and flow rates, and controls valve positions for efficient power generation in thermal power plants.
• Combined-Cycle Power Plants: Integrates with gas/steam turbine controls and balance-of-plant (BOP) systems for coordinated operation and performance optimization.
• Industrial Automation: Provides signal acquisition and control for PLCs, sensors, and actuators in refineries, chemical plants, and offshore platforms, supporting harsh environment operation.
• Condition Monitoring: Supports pulse accumulator and RTD/thermocouple inputs for vibration analysis and temperature monitoring, enabling predictive maintenance and reducing unplanned downtime.
• Turbine Retrofits: Direct replacement for legacy I/O modules in Mark VIe upgrades, enhancing signal acquisition capabilities and diagnostic features without requiring system reconfiguration.
• Process Control: Monitors and controls process variables in chemical processing, pulp and paper, and water treatment plants, ensuring compliance with quality and safety standards.
• Hazardous Environments: Operates safely in UL Class I Division II and ATEX Zone 2 locations, ensuring compliance with safety standards for explosive atmospheres.

Compatibility and Integration

• Mark VIe Ecosystem: Fully compatible with Mark VIe/VIeS controllers (e.g., IS220UCSAH1A), I/O modules (e.g., IS220PDOAH1A, IS220PTURH1A), and terminal boards, ensuring seamless IONet communication.
• IONet Architecture: Optimized for Mark VIe IONet protocol, providing deterministic data transfer for real-time control applications.
• ControlST Software: Configured and monitored via ControlST V07.02.00C or later, supporting channel configuration, diagnostic alerts, and data logging.
• Terminal Boards: Works with DS3800NTBH and DS3800NTBJ terminal boards for secure signal wiring and termination, supporting independent channel commissioning.
• Redundant Power Supplies: Operates with Mark VIe controller backplane power (5V DC) and integrates with redundant power sources (e.g., IS230JPDGH1B) for maximum system availability.
• Documentation: Detailed guidelines available in the GE Mark VIe System Manual (GEH-6855, Vol. I) and ControlST Configuration Guide, including wiring diagrams and channel configuration instructions.
