Product Introduction
-
Brand: GE
-
Series: Mark VIe I/O Modules
-
Model: IS220PRTDH1B
-
Product Type: RTD (Resistance Temperature Detector) Input Module
-
Description:
The IS220PRTDH1B is a precision RTD input I/O pack designed for industrial control systems within the Mark VIe architecture. It accepts RTD (platinum resistance) sensor inputs—such as Pt100 or Pt1000 types—and converts the resistance signal into digital data for the control system. This module is engineered for high‑reliability measurement in applications like turbine control, power generation, petrochemical plants, and other heavy‑industrial environments where accurate temperature monitoring is essential. The module supports multiple input channels, high resolution measurement, rugged environmental tolerance, and integration with the Mark VIe backplane and network infrastructure.

Applications
Typical application fields for the IS220PRTDH1B module include:
-
Power generation plants: Monitoring critical temperature points such as turbine casings, bearing temperatures, exhaust gas paths, feedwater heaters.
-
Oil & gas / petrochemical industries: Using RTD sensors for temperature measurement on pipelines, heat exchangers, reactor vessels, process pipes—especially in hazardous/explosive zones.
-
Heavy industrial automation: In plants with harsh environmental conditions (vibration, temperature extremes, dust), the RTD module provides reliable temperature input data for control systems.
-
DCS / PLC / turbine control systems: As part of the Mark VIe I/O rack architecture, the module feeds temperature data into the control logic, allowing precise monitoring, alarm/trip logic, optimization of thermal processes.
Advantages
The IS220PRTDH1B module offers several distinct advantages:
-
High‑precision measurement – Supports accurate RTD input with low drift and high resolution, enabling reliable temperature control.
-
Multi‑channel input – Up to 8 channels in one module reduce rack space and wiring complexity compared to single‑channel solutions.
-
Rugged industrial design – Capable of withstanding harsh conditions (temperature range, vibration, electrical noise) common in power plants and heavy industry.
-
Seamless integration – Fully compatible with Mark VIe rack/backplane systems, sharing diagnostics, communications and maintenance infrastructure.
-
Flexible wiring support – Works with 2/3/4‑wire RTD sensors and compensates for lead resistance, improving installation flexibility.
-
Hazardous‑area capable – Versions include certifications for ATEX/UL/Zone/Division 2, enabling use in explosive gas environments.
-
Efficient maintenance – Front‑panel diagnostics and integration with system tools allow quicker fault identification and replacement, reducing downtime.
-
Cost‑effective footprint – Multiple measurement channels in a compact module help reduce overall cabinet size and wiring cost.
