Product Description

Product Parameters

Advantages and Features

1. High-Density Bidirectional Signal Handling: The GE IS200EDSLH2ABB offers 24 bidirectional channels (12 input isolation + 12 output distribution), enabling simultaneous isolation of incoming field signals and distribution of processed signals to downstream modules—ideal for complex DCS signal routing scenarios.
2. Industrial-Grade High-Voltage Isolation: With 1000 V AC channel-to-channel isolation and 1500 V AC field-to-system isolation, the GE IS200EDSLH2ABB effectively blocks electromagnetic interference and voltage transients, protecting sensitive Mark VIe control modules from damage caused by field-side electrical faults.
3. Multi-Destination Signal Distribution: Each isolated input channel supports signal distribution to up to 3 output modules, eliminating the need for additional signal splitters and simplifying system wiring while maintaining signal integrity.
4. Low-Latency Signal Transmission: Boasting a maximum signal delay of ≤ 2 ms, the module ensures real-time signal transfer, critical for time-sensitive control loops such as turbine emergency shutdown systems and process safety interlocks.
5. Seamless Mark VIe Ecosystem Integration: Fully optimized for GE’s Mark VIe DCS, the GE IS200EDSLH2ABB integrates seamlessly with the system’s I/O modules and control logic units, sharing isolated signals via the high-speed backplane without compatibility bottlenecks or signal degradation.

Application Cases in Application Fields

1. Gas Turbine Signal Protection: A large gas-fired power plant in North America integrated the GE IS200EDSLH2ABB into its turbine control system. The module isolated safety interlock signals (e.g., emergency stop, over-vibration) from the plant’s high-EMI environment and distributed them to both the main control module and backup safety module. This prevented false shutdowns caused by interference, reducing unplanned turbine outages by 32%.
2. Steam Turbine Signal Routing: A coal-fired power plant in Europe deployed the GE IS200EDSLH2ABB to manage signal distribution for its boiler and turbine subsystems. The module isolated water level and pressure signals from the harsh boiler environment and routed them to the DCS’s control logic module, data logging module, and alarm system simultaneously. Its high isolation level withstood voltage spikes, improving signal reliability by 40%.
3. Petrochemical Process Signal Integrity: A petrochemical complex in the Middle East used the GE IS200EDSLH2ABB for its distillation column control system. The module isolated and distributed flow rate and temperature signals across multiple control loops, ensuring that each loop received accurate, interference-free data. This enhanced process control precision, reducing product quality deviations by 18% and cutting waste by 22%.
4. Combined-Cycle Power Plant Signal Coordination: An Asian combined-cycle power plant adopted the GE IS200EDSLH2ABB to unify signal isolation and distribution across gas and steam turbine subsystems. The module’s bidirectional channels streamlined signal flow between the two subsystems, while its multi-destination distribution reduced the number of wiring connections by 25%, simplifying maintenance and improving system scalability.

Selection Suggestions and Precautions

Selection Suggestions

1. Prioritize Mark VIe DCS Deployments: The GE IS200EDSLH2ABB is purpose-built for GE’s Mark VIe system. Choose this module if your industrial control system relies on Mark VIe to ensure seamless compatibility, full feature access, and optimal signal integration with existing DCS components.
2. Opt for High-Interference Environments: Select the GE IS200EDSLH2ABB for facilities with strong electromagnetic interference (e.g., power plants, steel mills) as its high-voltage isolation and EMI shielding effectively protect sensitive control signals from corruption.
3. Match Complex Signal Routing Needs: This module is ideal for large-scale DCS installations requiring multi-destination signal distribution (e.g., combined-cycle power plants, petrochemical complexes), as it eliminates the need for redundant isolation and distribution components.

Precautions

1. Configure Signal Direction Properly: Ensure correct configuration of bidirectional channels (input/output) via GE’s official software to avoid signal conflicts. Misconfiguration can disrupt signal flow and damage connected modules.
2. Ensure Stable Backplane Power: The module draws power from the Mark VIe backplane. Install voltage stabilizers if the backplane power is prone to fluctuations, as unstable power can compromise isolation performance and signal transmission accuracy.
3. Proper Wiring & Shielding: Use twisted-pair shielded cables for field wiring to minimize external interference. Follow GE’s wiring guidelines to separate input and output wiring, preventing cross-talk and maintaining the GE IS200EDSLH2ABB’s isolation effectiveness.
4. Anti-Static Handling: Use anti-static wristbands and packaging when installing or maintaining the GE IS200EDSLH2ABB, as static electricity can damage its sensitive isolation components and reduce operational lifespan.
5. Regular Isolation Testing: Periodically test the module’s isolation performance via specialized equipment to verify it meets the 1000 V/1500 V rating. Replace the module promptly if isolation degradation is detected to avoid system reliability risks.
