Description

IS220PTCCH2A THERMOCOUPLE INPUT PACK

Product Description

IS220PTCCH2A is a thermocouple input pack developed by General Electric. It is a part of Mark VIe control system. The Thermocouple Input (PTCC) pack serves as the intermediary between one or two I/O Ethernet networks and a thermocouple input terminal board. This pack facilitates the acquisition of thermocouple data and incorporates essential components for seamless integration within the Mark VIe distributed I/O system.

Pack Components

Processor Board: Common to all Mark VIe distributed I/O packs, this board handles overall processing tasks.
Acquisition Board: Specifically tailored for thermocouple input functionality, this board manages the acquisition of thermocouple data.

Functionality

The PTCC pack can accommodate up to 12 thermocouple inputs, with the capability to handle 24 inputs when two packs are employed.
In a TMR configuration with the terminal board, three packs are utilized with three cold junctions, providing 12 available thermocouples.

Input and Output

Input to the pack is facilitated through dual RJ45 Ethernet connectors and a three-pin power input, ensuring efficient connectivity.
Output is directed through a DC-37 pin connector, directly mating with the associated terminal board connector for streamlined communication.

Analog Input Hardware features

The Analog Input Hardware forms a crucial component of the PTCC input board, facilitating the acquisition of signals from thermocouples wired to the terminal board. This hardware module ensures accurate and reliable conversion of mV-level signals into digital data for further processing within the system.
Functional Components:
- Signal Acceptance: The input board is capable of accepting signals from up to 12 thermocouples wired to the terminal board.
- Analog Input Section: This section comprises six differential multiplexers, a main multiplexer, and a high-resolution 16-bit analog-to-digital converter (ADC). These components work in tandem to process analog signals effectively.
- Multiplexers: The presence of differential and main multiplexers allows for efficient selection and routing of input signals to the ADC, ensuring optimal signal processing.
- Analog-to-Digital Converter (ADC): The 16-bit ADC performs the crucial task of converting analog signals into digital data with high precision and accuracy.
Filtering and Sampling:
- Hardware and Firmware Filters: Each input signal is subjected to both hardware and firmware filters to minimize noise and ensure signal integrity.
- Sampling Rate: The ADC operates at a sampling rate of up to 120 Hz, enabling rapid and accurate conversion of analog signals into digital format.
Data Processing:
- Data Transmission: Upon conversion, the digital data is transmitted to the adjacent processor board for further processing and analysis. Integration with Processor Board: The seamless integration between the analog input hardware and the processor board allows for efficient data transfer and system operation.
