Overview

IS200DTCTH1A is a thermocouple input module developed by GE as part of the Mark VI control system. It plays a crucial role in acquiring accurate temperature data from thermocouples and transmitting it to the control system for processing. This module is integrated into a standard VME card rack, which is available in 13-slot or 21-slot configurations, depending on system requirements. Inputs from field devices are wired through termination boards that include either barrier-type or box-type terminal blocks. These boards also offer passive signal conditioning, enhancing signal quality before it reaches the control module.

Key Features

High Accuracy and Precision:

The module ensures reliable temperature measurements with minimal deviation. Accuracy is typically defined either as a percentage of the measured value or in degrees Celsius, making it suitable for high-performance industrial applications.

Multi-Thermocouple Compatibility

It supports a wide range of thermocouple types including:

• Type K
• Type J
• Type T
• Type E
• Type N

This versatility allows the module to be used across different applications and industries, such as power generation, manufacturing, and process automation.

Analog and Digital Output Options

• Analog Outputs: Common output signals include 4–20 mA, 0–10 V, or 0–5 V, offering continuous representation of temperature data.
• Digital Outputs: Supports interfaces such as RS-485, Modbus, or Ethernet for integration with digital control systems or SCADA/data acquisition systems.

Built-in Calibration

Certain versions of the module offer internal calibration functionality to maintain accuracy over time. This helps mitigate signal drift and ensures long-term measurement stability.

Signal Conditioning Capabilities

Advanced signal conditioning features include:

• Noise filtering
• Signal amplification

These functions enhance the signal quality, minimize electrical interference, and ensure clean, accurate data transmission to the control system.

Technical Attributes of the Control System

• Digital Signal Processing (DSP): Each I/O card, features a TMS320C32 DSP (Digital Signal Processor) that performs:
• Real-time digital filtering: Conversion of data to 32-bit IEEE-854 floating-point format. The filtered data is then written to dual-port memory, accessible by both the DSP processor and the VME bus.
• Modular Hardware Architecture: The Control Module also includes Internal Communication Card, Main Processor Card (occupies two slots), Optional Flash Disk Card.
• Each card is housed within a dedicated slot in the VME rack, offering modular scalability and easy maintenance.
