IS400TCATH1A GE MKVI, Analog Module Terminal Board

Description:

The IS400TCATH1A is a device which is called a terminal board. The IS400TCATH1A is one of many component parts in the Mark VI series made by General Electric or GE. The Mark VI and the other series in the Mark lineup have been used to manage all the of the processes of gas and steam turbines 1969, when the Mark I was first introduced. The Mark VI Turbine Control System Series that this IS400TCATH1A TMR Core Assembly Terminal Board was originally manufactured for has to be defined as quite the significant functional upgrade upon the previously-developed industry standard of the Mark V Turbine Control System Series, as this TMR Core Assembly Terminal Board product's Mark VI Series added the alternative energy-geared wind turbine possible application onto the gas and steam-based applications seen with the rollout of the Mark V Series as mentioned before.

Hardware Tips and Specifications

The IS400TCATH1A is a long printed circuit board which is rectangular. Three (3) long green terminal blocks are sitting on the left edge of the IS400TCATH1A. Each of these terminal blocks contains multiple terminals that are small and made from silver metal. Sitting right next to the terminal blocks on the bottom half of the IS200TCATH1A is a collection of pink capacitors. These capacitors are small and round. These capacitors have been ordered into two (2) rows of at least twenty (20) capacitors each. Three (3) additional pink capacitors are situated near the center of the lower edge of the IS400TCATH1A. On the upper half of the IS400TCATH1A next to the terminal blocks is a series of jumper pins. These jumper pins have been lined up in two (2) rows of twelve (12) sets. Every set contains three (3) small metal jumper pins. Two (2) potentiometers, sometimes alternately called variable resistors, are featured on the IS400TCATH1A. One (1) of these potentiometers has been placed near the top of the IS400TCATH1A in the center and the other is situated directly opposite to it on the bottom part of the IS400TCATH1A. The potentiometers are solid and light grey in color.

Features
TCAT generates three 4-20 mA voted signals, contributing to the precision of the system's output functionality. To facilitate these connections, the TCAT features a comprehensive array of field wire terminal points, with 120 pluggable Euro-style box terminals ensuring secure connections. Terminal points are organized into three groupings: one set of 48 terminals, another set of 24, and a final set of 48, enhancing the organization and accessibility of the system.
Integrated JGPA, situated adjacently to the terminals, supplements the system's capabilities. It provides an additional twelve 24 V dc outputs tailored for 4-20 mA devices, as well as dedicated terminals for shielding wires. The power supply to the JGPA emanates from TCAT connectors P3 or P4, employing a diode-or arrangement that combines power from the connected PCAA modules. This setup ensures reliable power distribution and stability within the system.
The terminal board's multifaceted role in the system includes enhancing I/O terminal capacity, managing diverse input signals, and providing a streamlined mechanism for generating output signals. This strategic allocation of power, comprehensive field wire terminal points, and collaboration with the adjacent JGPA board all contribute to the overall efficiency, reliability, and precision of the system's analog functionalities.
 Characteristics
Twelve seismic, twelve LVDT, twenty four 4-20 mA, and two magnetic pulse rate inputs are available. Each of the twenty-four 4-20 mA inputs has its own 24 V dc power source, with half on TCAT and the other half on an adjacent JGPA board.
TCAT outputs are made up of three voted signals ranging from 4 to 20 mA. 120 pluggable Euro-style box terminals provide field wire terminal points. Terminal grouping consists of 48 terminals, 24 terminals, and 48 terminals again. A JGPA board next to the TCAT field terminals adds twelve more 24 V dc outputs for 4-20 mA devices and shield wire terminals.
Connector P3 or P4 supplies power to JGPA and acts as a diode-or for power from connected PCAA modules.
Terminal board is connected to one or more PCAA modules via pairs of 68-pin cables. PR1 and PR2 are routed to a PCAA that is linked to the R IONet. PS1 and PS2 are connected to a PCAA via the S IONet. PT1 and PT2 connect to a PCAA that is linked to T IONet. On each cable connection, it generates an electronic ID. Cables are always used in pairs, and the electronic ID is used by PCAA to ensure that the correct TCAT cables are in place.
