General Electric IS200TRTDH1CCC Mark VI RTD Input Terminal Board

Product Description

Overview

The IS200TRTDH1CCC is a high-precision Resistance Temperature Detector (RTD) input terminal board designed by General Electric for the Mark VI control system. This module provides a reliable interface between field-installed RTD sensors and I/O processors, converting resistance measurements into digital temperature values. The CCC revision features a conformal coating for enhanced protection against moisture, dust, and industrial contaminants.

Key Features

High-Density Input

• Supports up to 16 three-wire RTD inputs for comprehensive turbine temperature monitoring.

• Two barrier-type terminal blocks with 24 connections each ensure organized, secure wiring.

• Accommodates wire gauges up to #12 AWG.

Signal Conditioning and Measurement

• Provides 10 mA non-continuous excitation current to each RTD to minimize sensor self-heating.

• Compatible with multiple RTD types: 10, 100, 200 Ω Platinum; 10 Ω Copper; 120 Ω Nickel.

• Voltage measurement span: 0.3532 to 4.054 V, offering high resolution across operational ranges.

• Maximum allowable lead resistance: 15 Ω (including cable).

System Reliability

• Hardware and software high/low limit checks for immediate fault detection.

• Integrated noise suppression circuitry to prevent signal interference and transient surges.

• ID chip verification ensures correct module identification and prevents system errors.

Installation and Integration

• Shield terminal strips located adjacent to each terminal block for effective grounding.

• Compatible with three 37-pin connectors for direct connection to VRTD processor boards.

• Designed for hot-swap capability in high-availability systems.

Applications

Ideal for gas and steam turbine monitoring, the IS200TRTDH1CCC ensures accurate readings for bearings, exhaust systems, lube oil, and other temperature-sensitive components in industrial plants.

Technical Specifications

Frequently Asked Questions

What is the IS200TRTDH1CCC?
It is a high-accuracy RTD input terminal board designed for GE Mark VI systems to monitor temperature via multiple sensors.

How does the board handle out-of-range signals?
Hardware and software limit checks trigger alarms for high/low conditions, and the RESETSYS command clears faults after corrective action.

Why is lead resistance important?
To maintain precise measurements, total lead resistance, including cables, must not exceed 15 Ω.

What does the ID chip do?
Each connector’s ID chip stores board type, serial number, revision, and connector location, ensuring proper system compatibility.

Similar Model Comparison
The IS200TRTDH1CCC is comparable to IS200TRTDH1CCB but adds a conformal coating for environments with higher contamination risk.
