Product Description

The GE IS210DTRTH1A DIN-rail Mounted Compact Terminal Board is a specialized component within General Electric’s high-reliability control systems. The board’s primary function is to serve as a Trip Relay Terminal Board (DTRT), providing the physical interface and termination points for critical trip signals used in turbine and generator protection.

As a terminal board, the GE IS210DTRTH1A (Placeholder Link: GE Automation Solutions Product Page) facilitates the connection between field wiring (from sensors, relays, and actuators) and the main processor board (often the VTUR I/O processor) via a dedicated cable. It is a simplex version, meaning it supports a single set of I/O circuits. The board is designed for DIN-rail mounting, allowing for easy and high-density installation within the control cabinet.² The GE IS210DTRTH1A (Placeholder Link: GE Automation Solutions Product Page) is critical in applications where reliable and high-speed tripping of the turbine is necessary to prevent damage. This board typically handles up to six trip functions that interface with a dedicated relay driver board (like DRLY) and the main controller.³ The GE IS210DTRTH1A (Placeholder Link: GE Automation Solutions Product Page) is compact and uses high-density terminal blocks for reliable field wiring connections.

Advantages and Features

• Critical Safety Interface: Provides a dedicated, high-integrity termination point for vital turbine trip circuits, ensuring fast and reliable protective actions.
• High-Density Design: The compact, DIN-rail mounting form factor saves valuable cabinet space compared to larger, older terminal boards.
• Simplified Wiring: Uses high-density terminal blocks and a single cable connection to the I/O processor, simplifying field wiring and maintenance.
• System Compatibility: Seamlessly integrates into the GE Mark VI/VIe architecture, leveraging the system’s noise suppression and diagnostic features.

Application Areas and Use Cases

The GE IS210DTRTH1A is exclusively used in critical control systems for rotating machinery:

• Gas and Steam Turbine Controls: Essential component for the physical connection of overspeed trips, high-vibration trips, emergency stops, and other critical protective circuits.
• Power Generation: Used in the control panels for generators and auxiliaries where GE Mark VI/VIe systems are deployed.
• Industrial Process Protection: Applications requiring the highest level of machinery protection and fast shutdown capability.

Competitive Comparison

The GE IS210DTRTH1A competes with specialized high-density terminal boards from other safety-rated or high-availability control platforms:

Selection Advice

You should select the GE IS210DTRTH1A DIN-rail Mounted Compact Terminal Board only when:

1. You are performing maintenance, repair, or planned expansion within a GE Mark VI or Mark VIe control system that requires a Trip Relay Terminal Board.
2. The system documentation specifically calls for the DTRT function and the IS210 compact form factor to interface with the VTUR processor.
3. You require a specialized, certified interface for critical protective functions where the speed and reliability of the trip signal are paramount.

Important Considerations

• Compatibility: Always verify that the hardware revision (H1A) of the GE IS210DTRTH1A (Placeholder Link: GE Automation Solutions Product Page) is compatible with the version of the I/O processor (VTUR) and the overall system software being used.
• Wiring Standards: Use proper wiring practices for protective circuits, including shielded cable and correct grounding, as specified in the GE installation manuals (e.g., GEH-6725) to prevent noise interference.
• Maintenance: Ensure that the terminal screws on the Euroblock connectors are torqued to the manufacturer’s specification to maintain a reliable, low-resistance connection for the critical trip signals.
