Product Describe：
Resistance Temperature Device Input Module
8-channel resistance temperature detector input module
Supports standard 3-wire
and 4-wire RTD configurations
The IS220PRTDH1A functions as a high-performance resistance temperature detector input pack within the General Electric Mark VIe Series framework utilized in distributed control systems. This hardware establishes the primary electrical interface between an RTD input terminal board and one or more input-output Ethernet networks. The pack incorporates a standard processor board shared across all Mark VIe distributed input-output units alongside a dedicated acquisition board built specifically to process temperature measuring functions.
The module supports full-function online hot-swapping
The module features full galvanic isolation for internal RTD input circuits
The module is equipped with dual RJ45 Ethernet ports, supporting direct connection to the redundant IONet network topology unique to the GE Mark VIe system
A single input-output pack handles up to eight RTD inputs while the compatible TRTD terminal boards can handle up to sixteen RTD inputs. Output transmission relies on a DC-37 pin connector that mates directly with the associated terminal board connector while front panel indicator light-emitting diodes display real-time visual diagnostics. Network infrastructure scaling operates across three distinct configurations depending on system redundancy requirements.
A simplex control setup deploys one input-output pack alongside one or two network connections. A dual architecture utilizes two input-output packs paired with one or two network links. For high-availability environments a triple modular redundant architecture coordinates three separate input-output packs with each unit maintaining a single network connection. The input circuitry undergoes complete galvanic isolation by the pack hardware which requires specific matching modifications regarding terminal board transient protection.
The module features full compatibility with the TRTDH1D TRTDH2D and SRTD terminal boards but it remains incompatible with the DIN-rail mounted DRTD board. Regarding operational scanning dynamics the H1D version of the terminal board offers filtering characteristics optimized for the standard pack scan rate. When choosing the rapid scan rate selection the H2D version of the terminal board provides less filtering to enable proper high-speed data acquisition performance.

Gas Turbine Power Generation
Precisely collects main bearing and thrust bearing metal temperatures of gas turbine generator sets to prevent bearing pad physical burnout caused by frictional overheating.
Thermal Power Steam Turbines
Monitors bearing temperatures at the front and rear shaft seals of high-pressure steam turbine rotors, evaluating fluid-film bearing conditions under high-speed operation in real time.
Nuclear Power Control Systems
Monitors motor stator winding temperatures of Reactor Coolant Pumps (MCP) with high reliability, utilizing full circuit galvanic isolation to eliminate heavy electromagnetic interference.
Refining & Petrochemicals
Collects internal coil temperatures of high-power recycle hydrogen compressor drive motors, utilization of the redundant IONet to prevent false unit trips caused by single-point network failures.
Air Separation & Cryogenic Industry
Monitors the lubricating oil supply and return temperatures inside bearing housings of oxygen turbo-compressors within ultra-large air separation units with high precision.
Iron & Steel Blast Furnace Systems
Collects return water temperatures of blast furnace blower support bearings and large cooling water systems via multi-channels, ensuring the physical heat dissipation safety of core power equipment.
When using the IS220PRTDH1A module, verify that redundant IONet communication via the dual RJ45 ports is normal before performing hot-swapping to prevent accidental master system trips. The RTD type configured in the software must strictly match the physical field sensor, and mixing different resistance curves is prohibited. Run 3-wire or 4-wire lead wires through grounded metal conduits and avoid routing them alongside high-voltage power cables to preserve the module's internal galvanic isolation.
Additionally, fully tighten the retaining screws when securing the module to the external terminal board to prevent loose pin contact from vibration, and maintain a dry environment to eliminate connector oxidation.

Technical notes
Technical notes
It operates on 28 Volts DC power from a paired terminal board and features integrated sensor open-circuit and short-circuit fault detection. The unit also includes front status light-emitting diodes and supports full online hot-swapping under system power.
It is a resistance temperature detector (RTD) input Input/Output (I/O) pack for the GE Mark VIe control system, utilized to acquire temperature signals from field-level RTD sensors.
What is the primary function of the IS220PRTDH1A?
It measures the resistance values of field RTD sensors, converts them into precise digital temperature data, and transmits them at high speed to the main controller via dual Ethernet (IONet) links.
How many RTD channels can the IS220PRTDH1A support?
A single IS220PRTDH1A I/O pack supports the input and processing of up to 8 channels of RTD temperature signals.
What wiring configurations does the IS220PRTDH1A support?
It supports industry-standard 3-wire and 4-wire RTD wiring configurations to automatically eliminate measurement errors caused by lead wire resistance.
Which specific RTD types are supported by the IS220PRTDH1A?
It is compatible with various standard RTDs, including the most common 100-ohm platinum resistors (Pt100, such as European and American curves), 10-ohm copper resistors (Cu10), and nickel resistors (Ni120).
