Product Description
This DS200TBQAG1ABB Thermocouple Termination Module was originally manufactured by General Electric for use in their Mark V Turbine Control System Series, as described above. The Mark V Series that this DS200TBQAG1ABB PCB belongs to has specific applications in the control and management systems of compatible wind, steam, and gas turbine automated drive assemblies, and is considered a General Electric legacy series given its original manufacturer's production discontinuation in the years following its initial release. While deemed as a legacy series, the Mark V Turbine Control System Series that this DS200TBQAG1ABB Thermocouple Termination Module belongs to is also considered one of the final General Electric Mark product series to make use of their patented Speedtronic control system technology, a technology first introduced alongside the rollout of the Mark I Series in the late 1960s. This DS200TBQAG1ABB PCB, while definable as a Thermocouple Termination Module in its own right, is not the originally-developed product of this functionality to feature within the Mark V Series; that would be the DS200TBQAG1 Thermocouple Termination Module missing all three of this DS200TBQAG1ABB PCB's three product revisions.
Hardware Tips and Specifications
As with any product featured in General Electric's Mark V Turbine Control System Series, this DS200TBQAG1ABB PCB makes use of its own series of functionality-introducing hardware components and component specifications. The GE RST Terminal Board DS200TBQAG1ABB features 2 90-pin terminal blocks to support a maximum of 180 signal wires. The terminal blocks are labeled TB1 and TB2. The GE RST Terminal Board DS200TBQAG1ABB also contains 3 20-pin connectors. As indicated in this DS200TBQAG1ABB product offering's original instructional manual materials and documentation, this DS200TBQAG1ABB PCB's assembly does not make use of any one manually-moveable hardware jumper or customizable piece of hardware, although several unique connectors are available to its assembly. Some of the connectors established on the base circuit board of this DS200TBQAG1ABB product offering include:
- The JAR TCQA and TCCA Boards Thermocouple Signals 1-15 and Cold Junction Signals Connector
- The JAS TCQA and TCCA Boards Thermocouple Signals 16-30 and Cold Junction Signals Connector
- The JAT TCQA and TCCA Boards Thermocouple Signals 31-45 and Cold Junction Signals Connector
All of the above DS200TBQAG1ABB Thermocouple Termination Module connectors listed have been named through a combination of their factory-printed nomenclature labels, Mark V Series interfacing potentials, and specific signal applications within the Mark V Turbine Control System Series. Both the TCQA and TCCA Boards so important to the functionality of this DS200TBQAG1ABB device's greater Mark V Series automated drive assembly are additionally available for repair or replacement here today.
When you first install the GE RST Terminal Board DS200TBQAG1ABB the written materials that come with the board describe the signal connections that can be made to the terminals. After you understand which terminal to connect a signal wire to, you must strip the insulation off the end of the signal wire to expose roughly 0.5 inch. Then, loosen the screw and insert the wire into the terminal. You can next tighten the screw to secure the wire. Pull the wire gently to check that it is installed in the terminal and cannot easily be removed. However, when you replace the board you only must remove the signal wires from the old board and reinstall them in the same terminal in the replacement board. Because you potentially have multiple signal wires to reattach, care must be taken to ensure you attach them to the right terminal. Before you start, check with individuals that are qualified to remove power to the drive. Installers that are familiar with the installation of the drive will understand the power cabling, signal cabling, and ground wiring. An electrician familiar with the installation would also be qualified to remove the power. Some capacitors on the boards in the drive retain power after the power is removed from the drive. However, after 30 seconds the power exits the capacitors and other components and the board is free of current.
