GE IS210DTURH1A Terminal Board
In industrial processes where accurate temperature measurement is paramount—from monitoring
steam turbine exhaust in power plants to controlling batch reactor temperatures in chemical facilities
—the integrity of the signal path from sensor to controller is as critical as the sensor itself. The GE
IS210DTURH1A Terminal Board is engineered to be the most reliable connection point in this chain: as
a dedicated thermocouple terminal board for GE's Mark VIe Distributed Control System (DCS), it
provides a robust, noise-immune interface between field-installed thermocouples and Mark VIe input
modules. Unlike generic terminal blocks assemblies that lack proper isolation or protection, this board
is purpose-built for the harsh realities of industrial environments—offering superior electrical
isolation, built-in surge protection, and rugged construction. Whether you're connecting dozens of
thermocouples in a boiler or a single critical sensor on a turbine bearing, the IS210DTURH1A acts as
the "fortress gate" of your temperature monitoring system—ensuring every microvolt of
thermoelectric signal reaches the controller accurately and reliably.
The IS210DTURH1A is designed to simplify the connection of various thermocouple types, making it a versatile choice for any application:
Broad Thermocouple Support: Accommodates all standard industrial thermocouple types (J, K, T, E, R, S, B, N), allowing for mixed sensor installations without the need for multiple board types.
Flexible Terminal Design: Features high-quality, screw-clamp terminal blocks that accept a wide range of wire gauges (typically 22-14 AWG), ensuring secure connections for both fine control wiring and heavier field cables.
Clear Labeling & Layout: Each terminal is clearly marked for positive (+) and negative (-) connections, with ample spacing between channels to prevent wiring errors and facilitate easy installation and maintenance.
Industrial environments are rife with electrical noise and transient voltage spikes that can corrupt delicate thermocouple signals or damage sensitive control electronics. The IS210DTURH1A addresses these challenges with:
High-Voltage Channel Isolation: Provides 2.5kV AC isolation between each thermocouple channel and between channels and the system ground. This isolation is crucial for breaking ground loops and preventing noise from one sensor from affecting others.
Cold-Junction Compensation (CJC) Support: Integrates precision reference junctions (isothermal blocks) to facilitate accurate cold-junction compensation by the connected Mark VIe input module (e.g., IS200DTCIH1A), ensuring measurement accuracy across varying ambient temperatures.
Surge & Overvoltage Protection: Incorporates protection circuitry to safeguard against voltage transients that can occur during sensor disconnection or due to lightning strikes, preventing damage to the terminal board and the connected input module.
As a frontline component, the IS210DTURH1A is built to endure the toughest conditions:
Wide Operating Temperature Range: Functions reliably from -40°C to 70°C (-40°F to 158°F), making it suitable for installation in non-climate-controlled cabinets near heat sources.
Conformal-Coated PCB: The board's circuit board is protected with a conformal coating (per IPC-CC-830B), shielding it from dust, moisture, and chemical contaminants commonly found in industrial settings, thus extending its operational lifespan.
Mechanical Ruggedness: Designed to withstand the rigors of industrial installation and operation, including vibration and shock, ensuring long-term reliability.
The IS210DTURH1A is designed with the technician in mind, featuring capabilities that reduce downtime and simplify maintenance:
Visual Status Indicators: While the board itself may not have LEDs, its design facilitates easy access to each channel for quick visual inspection and troubleshooting. The connected Mark VIe input module can provide detailed diagnostics (such as open/short circuits) which can be traced back to specific terminals on the IS210DTURH1A.
Channel-Level Fault Isolation: By providing a dedicated connection point for each thermocouple, the board allows for easy identification and isolation of faulty sensors or wiring issues, reducing the time needed to locate and repair problems.
Hot-Swappable Design: In compatible configurations, the terminal board can be part of a hot-swappable I/O module assembly, allowing for replacement or maintenance without shutting down the entire system.
In coal, gas, or nuclear power plants, the IS210DTURH1A serves as the connection hub for numerous temperature sensors:
Turbine Bearings & Casings: Connects J or K-type thermocouples monitoring bearing temperatures, providing early warning of lubrication failure or misalignment.
Boiler Water Walls & Superheaters: Interfaces with K-type thermocouples measuring tube metal temperatures, preventing catastrophic overheating and tube rupture.
Result: Ensures reliable temperature monitoring of critical assets, enabling predictive maintenance and preventing costly unplanned outages.
In chemical processing facilities, precise temperature control is essential for product quality and safety:
Batch & Continuous Reactors: Connects E or K-type thermocouples to monitor reaction temperatures, ensuring optimal chemical conversion and preventing thermal runaway.
Distillation Column Trays: Interfaces with thermocouples measuring tray temperatures, enabling precise control of product separation.
Result: Maintains tight temperature control loops, ensuring consistent product quality and maximizing yield.
In steel and aluminum production, accurate temperature measurement is critical for material properties:
Arc & Induction Furnaces: Connects high-temperature thermocouples (e.g., R, S, B types) to monitor molten metal temperatures, ensuring proper alloy formation.
Heat Treatment Ovens: Interfaces with thermocouples controlling oven zones, ensuring parts are heated and cooled according to precise schedules for desired hardness and strength.
Result: Ensures the integrity of thermal processes, reducing material scrap and ensuring compliance with strict quality standards.
