Description:

The DS200DTBBG1A is a Terminal Board Digital Connector Card under Mark V series GE. The GE DS200DTBBG1A Terminal Digital Connector Board has two terminal blocks, each containing terminals for 95 signal wires. Three 50-pin connections are also included. JFF, JFG, and JFH are the IDs for the 40-pin connectors. There are also five jumpers and bayonet connectors. Because there are three 40-pin connectors on the board, it's crucial to keep track of which 40-pin ribbon wire is linked to which connector. It's critical to get the drive back in service after replacing the board if you want to regain productivity.

The DS200DTBBG1A is designed to provide a high-density, easily serviceable I/O interface for turbine control systems. It features two terminal blocks, each with terminals for 95 signal wires, for a total of 190 terminals. The board also includes three 50-pin connectors with bayonet-style connectors, making it easy to connect and disconnect ribbon cables. The DS200DTBBG1A serves as a Contact Input Expansion Termination Module in the Mark V Turbine Control System Series, allowing for the expansion of digital inputs. Each terminal block can accommodate 95 signal wires. The DS200DTBBG1A is typically located in the QD or C cores of the Mark V system.

The potential exists to have a maximum of 110 signal wires attached to the terminal blocks of the DS200DTBBGIA Contact Input Expansion Termination Module. This will be difficult to manage without a method to document where the separate signal wires are connected. One terminal block is assigned TB1 as the ID and the other terminal block is assigned TB2 as the ID. The separate terminals are numbered in sequence on each terminal block. So, to identify a specific terminal you use the terminal block ID and the number assign to the terminal. Some examples are TB1 90 and TB2 48. TB1 90 is terminal 90 on terminal block 1, while TB2 48 is terminal 48 on terminal block 2.

Now that some of the various hardware elements afforded to the assembly of this DS200DTBBGIA Conact Input Expansion Termination Module have been revealed, it is possible to explain the types of connectors compatible with this Mark V Series product. Some of the connector types used in conjunction with this DS200DTBBGIA Contact Input Expansion Termination Module include the JRR TCDA contact input connector, the JY 125 V dc DTBA board power connector, and the JRS/T connector, which is typically unused.
