GE DS200TCTGG1AFF

DS200TCTGG1AFF is a Simplex Trip Board in the General Electric (GE) Mark V series. It serves as a critical protection module for the GE Speedtronic Mark V gas turbine control system. By means of plug-in relays, it enables rapid power-off protection for gas turbines or other high-risk processes, ensuring safe shutdown of equipment under abnormal operating conditions.

Main Technical Specifications

• Operating Voltage: 24 V DC
• Power Consumption: Approximately 25 W; Weight: 2.95 lb (≈ 1.34 kg)
• Number of Relays: 21 plug-in relays, equipped with 3 50-pin connectors and 2 12-pin connectors
• Input/Output Interface: Digital I/O, supporting 0-10 V / 4-20 mA analog signals; some models provide communication interfaces such as RS-485 and Ethernet
• Operating Temperature Range: -40 °C ~ +75 °C
• Protection Level: IP65, vibration and shock resistant, compliant with IEC 61508-2 safety standards
• Dimensions/Weight: Approximately 180 mm × 130 mm × 50 mm; Weight: about 0.5 kg (wall-mounted type)

Product Features

• High Reliability: Designed specifically for high-risk industrial environments like gas turbines, featuring fast tripping, vibration resistance, and a wide temperature range.
• Modular Design: Plug-in relays and standardized connectors facilitate quick on-site replacement and maintenance.
• Multi-Functional Protection: Capable of implementing multiple protection logics such as overcurrent, overvoltage, and stalling, supporting user-defined tripping strategies.
• Communication Integration: Some models are equipped with RS-485/Ethernet interfaces, which can be connected to upper computers or SCADA systems to achieve remote monitoring and diagnosis.
• Easy Installation: Wall-mounted structure, fixed with matching metal strips, simple installation steps, and adaptable to various cabinet sizes.

Structure and Composition

• Main Board: A multi-layer PCB that integrates power supply, signal processing, and relay drive circuits.
• Plug-in Relays: 21 independent relay modules, fixed with metal strips for easy plugging and unplugging.
• Connectors: 3 50-pin connectors (marked JLY, JLX, JLZ) and 2 12-pin connectors (marked JN, JM) for power supply, signal, and communication lines.
• Power Module: Provides a 24 V DC regulated power supply, compatible with 90-132 VAC / 180-264 VAC input.
• Housing: A metal protective housing, meeting IP65 protection level, dustproof and waterproof.

Typical Application Fields

• Gas turbine control systems (Mark V series)
• Industrial sites requiring high-speed safe shutdown, such as power plants, petrochemical plants, and natural gas processing facilities
• Electronic circuit protection for high-voltage power systems (frequency converters, DC power supplies, drive devices)
• Critical safety nodes in process control and automation systems

Installation and Maintenance Points

• Pre-Installation Inspection: Confirm that the power voltage, ambient temperature, and humidity meet the specifications; check whether the connectors and relays are in good condition.
• Fixing Metal Strips: After inserting the plug-in relays into the corresponding slots, fix them with metal strips on both sides to prevent falling off due to vibration.
• Wiring Specifications: Connect the 50-pin and 12-pin connectors to the power supply, signal, and communication lines respectively according to the wiring diagram, ensuring firm wiring and clear identification.
• Function Testing: After power-on, use an on-site tester to check the on-off status of each relay and verify whether the tripping logic meets the settings.
• Regular Maintenance: Conduct a visual inspection and function verification every 6-12 months; if poor relay contact or loose metal strips are found, replace or re-fix them in a timely manner.
• Troubleshooting: In case of false tripping or failure to trip, first check whether the power supply and signal lines are abnormal; use an oscilloscope or multimeter to confirm the relay drive voltage; if necessary, replace the faulty relay or contact the supplier for maintenance.

Our Company: Product Range & Service Pledges

Our Service Pledges to Customers

• Pledge 1: We are committed to delivering products with consistent quality and exceptional after – sales support. While upholding strict quality standards, we strive to offer competitive and reasonable pricing to maximize customer value.
• Pledge 2: All products are sourced or procured in compliance with national or industry standards, ensuring they meet the required performance criteria. When used correctly, our products will have a service life comparable to or exceeding that of other similar products on the market. We also provide professional guidance to help customers select the most suitable product types and specifications based on their specific requirements.
• Pledge 3: (Note: The original content for Pledge 3 was not provided. To ensure the completeness of our service commitments, we recommend supplementing details such as technical consultation, customization support, or post – purchase training here.)
• Pledge 4: We prioritize on – time delivery. Under normal circumstances, customers can expect to receive their orders within 6 working days. For special cases (e.g., urgent orders, custom parts), we will work with customers to negotiate a flexible delivery timeline that aligns with their needs.
• Pledge 5: Since all products are manufactured by original overseas factories, after – sales service is provided directly by these manufacturers. The standard warranty period typically ranges from 6 months to 1 year, with specific terms subject to the original manufacturer’s policies. If a product experiences quality issues, and both parties confirm the problem stems from the manufacturer’s defects, we will facilitate the return of the product to the original factory for repair or arrange alternative solutions (e.g., replacement) as needed.
