GE IS220PRTDH1A Mark VIe RTD Input Module
Product Overview
The GE IS220PRTDH1A is a high-precision RTD (Resistance Temperature Detector) Input Module designed for GE’s Mark VIe control system, specialized in converting temperature signals from RTD sensors into digital data for industrial automation. As a core component of the IS220 Series, this module enables accurate temperature monitoring of critical machinery and processes, serving as a linchpin in power generation, oil & gas, and chemical processing. The IS220PRTDH1A integrates seamlessly with other Mark VIe components (e.g., controllers, communication cards), forming a robust architecture for mission-critical applications where precise temperature data is vital for safety and efficiency.
Featuring 8 independent RTD channels, the GE IS220PRTDH1A supports standard RTD types (Pt100, Pt1000, Cu100) with a measurement range of -200°C to +850°C, ensuring versatility across diverse industrial environments. Its 24-bit analog-to-digital converter (ADC) delivers ±0.1°C accuracy and 0.001°C resolution, capturing even minute temperature fluctuations—critical for monitoring turbine bearings, reactor walls, and other high-value assets. The module’s galvanic isolation (2500 V RMS) between channels and backplane prevents electrical interference, while its rugged design (conformal coating, MIL-STD-810G compliance) withstands vibration, shock, and extreme temperatures (-40°C to +70°C), making it ideal for harsh settings like offshore platforms and power plant turbine halls.
In automation ecosystems, the IS220PRTDH1A acts as the front-end for temperature data, feeding real-time measurements to the Mark VIe controller for process optimization and safety alarms. Its support for triple modular redundancy (TMR) configurations enhances reliability by cross-verifying readings across three redundant modules, ensuring fault tolerance in safety-critical systems. The hot-swappable design allows maintenance without system shutdown, minimizing downtime in 24/7 operations—an essential feature for industries where unplanned outages risk productivity and safety.

Key Features and Advantages
Ultra-Precise Temperature Sensing:
The IS220PRTDH1A’s 24-bit ADC and ±0.1°C accuracy ensure reliable measurement of critical temperatures, such as turbine bearing temperatures in power plants or reactor wall temperatures in chemical facilities. This precision prevents false alarms and enables early detection of abnormal heating, reducing the risk of equipment failure.

Multi-RTD Compatibility:
Support for Pt100, Pt1000, and Cu100 RTDs allows flexibility in sensor selection, adapting to different temperature ranges and environmental conditions. Users can configure each channel independently via GE’s Proficy software, eliminating the need for multiple specialized modules.

Robust Isolation:
2500 V RMS galvanic isolation between channels and the backplane protects against electromagnetic interference (EMI) and ground loops—common in industrial environments with high-voltage equipment. This isolation ensures signal integrity even in noisy settings like factory floors or refineries.

TMR Redundancy Support:
Designed for triple modular redundancy, the IS220PRTDH1A works with two identical modules to cross-verify readings. If one module fails, the system “votes” on valid data from the remaining two, ensuring uninterrupted operation and compliance with safety standards like SIL 3.

Maintenance suggestions:
Perform monthly visual inspections of front-panel LEDs to check for channel faults or power issues. Calibrate annually using a precision temperature bath and RTD simulator to maintain ±0.1°C accuracy. Clean module vents quarterly with compressed air to prevent dust buildup, especially in dusty environments. Store spare IS220PRTDH1A modules in anti-static packaging at 10–30°C with <50% humidity. Test spares annually to ensure functionality, particularly for critical applications with limited downtime tolerance.
