IS220PRTDH1A, Rev D — Resistance Temperature Device (RTD) Input Module

The IS220PRTDH1A is an RTD input pack used in GE’s Mark VIe / Mark VI control systems. Its main role is to connect RTD sensors to the control network, converting their resistance values (which vary with temperature) into digital signals for monitoring and control.


Key Features

  • 8 RTD channels — accepts up to eight RTD inputs.

  • 14-bit A/D conversion for accurate measurement.

  • Common-mode voltage range: ±5 V.

  • Lead resistance: up to 15 Ω per line.

  • Galvanic isolation between field inputs and the system.

  • Diagnostic capabilities — built-in self-tests, input limit checks, fault and status monitoring.

  • LED indicators on the front panel for power, Ethernet activity, and attention/faults.

  • Dual RJ45 Ethernet ports for communication.

  • Power input: nominal ~28 V DC.

Compatibility

  • Can be installed in simplex, dual, or triple modular redundant (TMR) systems.

Function

The pack measures resistance from RTD sensors, isolates and filters the signals, digitizes them, and communicates data to the Mark VIe system. It ensures accurate temperature monitoring while providing electrical protection and fault detection.
