Product Description
This DS200TCDAH1BHE General Electric product offering was originally designed and manufactured specifically for use in the Mark V Series. The Mark V Series is one of the more recently-developed General Electric product series utilizing the trusted automated industrial retailer's patented Speedtronic assembly type, and has specific applications in the control and management systems of steam, gas, or wind turbines compatible with General Electric products. This DS200TCDAH1BHE printed circuit board or PCB for short is better-definable by its functional product description as a Digital I/O Board, as revealed in original General Electric and Mark V Turbine Control System Series instructional manual materials. While this DS200TCDAH1BHE printed circuit board is definable as a Digital I/O or Input/Output Board, it is by no means the original product with this intended functionality to exists as a member of the Mark V Series; that would be the DS200TCDAH1 parent printed circuit board that makes use of a full table of three significant product revisions.
Hardware Tips and Specifications
The GE Digital I/O Board, model DS200TCDAH1BHE, is equipped with several components to facilitate its functionality within its greater Mark V Turbine Control System Series and Mark V Series automated drive assembly. It features 8 jumpers, an LED on the side of the board, and 2 3-pin connectors. The TCDA unit includes 1 block of 10 LEDs and 2 50-pin connectors. The DS200TCDAH1BHE also provides test points that enable qualified servicemen to conduct circuit testing. Additionally, the DS200TCDAH1BHE is located in the digital I/O cores <Q11>, <Q51>, and <Q21> if present. It is responsible for processing digital contact input signals from the DTBA and DTBB terminal boards, as well as contact output signals (relay/solenoid) from the two TCRA boards. These signals are transmitted via the IONET to the TCQC board in <R1> and <R2> if <Q21> is installed, and the CTBA terminal board in <R5>.
The DS200TCDAH1BHE functional product number is an additional viable source of original DS200TCDAH1BHE product-specific informations, beginning with the DS200 series tag embedded at the very beginning. The DS200 series tag at the start of the DS200TCDAH1BHE functional product number has dual naming functionality for this PCB, detailing its as a domestically-manufactured General Electric product with a normal Mark V Series assembly. The DS200 series tag is followed in the DS200TCDAH1BHE functional product number by the TCDA functional acronym, which itself is followed by the H1 series grouping tag detailing this DS200TCDAH1BHE product's unique conformal style of PCB coating and its group one Mark V Series grouping. The final three alphanumeric digits in the DS200TCDAH1BHE functional product number are telling of this printed circuit board's three significant product revisions, rated at B, H, and E grades respectively. Before making a final purchase decision on this DS200TCDAH1BHE Mark V Series product, it is important to realize that this product's three revisions alter its originally-identified performance specifications and dimensions.
For accurate diagnostics, the testing equipment, including calibrated probes, must be compatible with the board and in good condition. By touching the test points on the DS200TCDAH1BHE board and observing the readings obtained from running current through the circuit, the serviceman can analyze and troubleshoot any issues with the board. In case a trip condition is detected in the drive, the drive will be automatically shut down. These trip conditions are specifically designed to protect the drive from potential damage. For example, if the drive's interior overheats, an over-temperature trip condition is generated, triggering an automatic shutdown to safeguard the boards and components within the drive.
