GE DS200TCRAG1A Relay Output Board

GE DS200TCRAG1A Relay Output Board

Part Number DS200TCRAG1A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark V Function Module Availability In StockDS200TCRAG1A is a Relay Output Board manufactured and designed by General Electric as part of the Mark V LM Series used in GE Speedtronic turbine control systems. Up to 30 relays, designated K1 through K30, are housed on the TCRA, which is part of the digital cores. 

The digital IO cores each contain two of these boards. Only four relays are present on the TCRA board at position 4 of the Q11 core, and they are linked to the TCQE by the JO connector. Some applications employ these relays to control the gas manifold blow-off valves. Thirty relays are present in every other TCRA. To supply a power source to operate solenoids, the first 18 relays on TCRA in location 4 of "Q51" can be configured. This configuration is also possible for the first 16 relays on the TCRA board in position 5 of the Q11 and Q51 cores. On the DTBC and DTBD terminal boards, hardware jumpers are used to do this. Using the power connectors J19 and J20, two extra contact outputs (#47 and #48) can be wetted on the TCRA board in position five of either Q11 or Q51. 

The DTBD board in one of the cores receives 120/240 V ac power through connectors J19 and J20 from the PD core. For ignition transformers, these signals are typically employed. The TCDA boards in the digital cores write the signals to the TCRA boards that instruct them to open or close the relays. The TCQE board in the "R1" core sends signals to the TCRA board at position 4 of "Q11" in this manner. Q21's first 18 solenoid outputs are ineligible to be configured as solenoid power sources. 

 TCRA CONFIGURATION: HARDWARE: The hardware configuration for the DTBC and DTBD terminal boards is done at the terminal board level, which powers the relays or converts them to solenoids. SOFTWARE: The TCRA board does not have any software configuration. TCRA CONTACT OUTPUT CIRCUITS: Signals from the CSP are used to control the relays on the TCRA boards, which are then relayed to the STCA board through COREBUS and the IO Engines. 

The TCDA boards receive the signals from the STCA boards via the IONET after reading them. The instruction signals are then written by the TCDA board via the JO connector to energize the relays. The JS1 through JS8 connectors are used to connect the relay (open/close) to the DTBC and DTBD terminal boards.

ABOUT THE DS200TCRAG1A

Hardware Tips and Specifications

This DS200TCRAG1A product offering is a printed circuit board that makes use of its own series of hardware component inclusions and specifications to achieve a functional Mark V Series status. The GE Relay Output Board DS200TCRAG1A is populated with 30 plug-in relays. It also has 4 34-pin connectors and 4 12-pin connectors. The IDs assigned to the 34-pin connectors in this DS200TCRAG1A PCB's assembly are JOR, JOS, JOT, and JO. The IDs assigned to the 12-pin connectors are JS3, JS4, JS5, and JS6.  Because the GE Relay Output Board DS200TCRAG1A is populated with multiple relays which are delicate and easily broken off the board, it is important that you follow guidelines for handling the DS200TCRAG1A board when it is shipped to you. Hardware configuration is possible for this DS200TCRAG1A Relay Output Board, encouraged by the use of several manually-moveable hardware jumpers. These hardware jumpers, however, do no feature in the assembly of the DS200TCRAG1A Relay Output Board itself, instead existing on related Mark V Series terminal boards DTBC and DTBD, which are also available for repair and replacement through AX Control. This DS200TCRAG1A Relay Output Board has a normal Mark V Series assembly version, which is populated with many of the various streamlined hardware components standard to this turbine control system series; such as various rectifiers, diodes, capacitors, and resistors. One specifically-highlightable hardware component in this DS200TCRAG1A product's assembly is its set of various integrated circuits, which are described in detail in the above attached instructional manual. Some of the connectors in this DS200TCRAG1A PCB's assembly include:

The JO TCDA Board Gas Manifold Signal Connector

The JS1-JS8 DTBC/D Boards Relay Output Connectors

The JOR/S/T Connector

All of these previously-listed connectors important to the assembly of this DS200TCRAG1A Relay Output Board have been named through a combination of their specific application to the DS200TCRAG1A board, interfacing potentials, and factory-printed nomenclature labels, except for the above JOR/S/T Connector, which has not been named as such given the fact that it typically goes unused during normative functionality of this TCRA-abbreviated printed circuit board product offering. All of the connections made to the base board of the DS200TCRAG1A Relay Output board should receive at least some level of base protection from the thick, rudimentary daily wear and tear protection afforded to this DS200TCRAG1A PCB by its normal style of General Electric printed circuit board coating. Before making a final purchase decision on this DS200TCRAG1A Relay Output Board, it is important to be cognizant of the fact that its originally-introduced performance specifications and dimensions have been more than likely impacted as a function of this DS200TCRAG1A PCB's addition of a singular A-rated functionality-enhancing product revision.
