FUNCTIONAL DESCRIPTION:

DS200TCRAG1B is a Relay Output Board manufactured and designed by General Electric as part of the Mark V LM Series used in the Line of Microprocessor aero-derivative turbine Control Systems. The Relay Output Board (TCRA), located in the core and the core, contains up to 30 relays, K1 through K30. There are two of these boards in each of the digital I/O cores. The TCRA board in location four of the core contains only four relays, which are connected to the TCQE via the JO connector. These relays are used to operate the gas manifold blow-off valves in some applications. The other three boards contain the full 30 relays. The first 18 of these relays in the TCRA board in location four of the core can be powered to become solenoids. The first 16 of these relays on the TCRA board in a location five of both the and core can be wetted also. This is done using hardware jumpers on the DTBC and DTBD terminal boards. Two additional contact outputs, (#47 and #48), can be wetted on the TCRA board in a location five of either or using the power connectors J19 and J20. Connectors J19 and J20 bring 120/240 V ac power from the core to the DTBD board in one of the cores. These signals are typically used for ignition transformers. The signals to open or close the relays are written to the TCRA boards via the TCDA boards in the and cores. The signals for the TCRA board in location four of the core are read from the TCQE board in the core.

TCRA CONNECTORS:

• JO - Writes the signals from the TCDA board to the TCRA board in location five for , and . Writes the signals from the TCDA board to the TCRA board in location four of the and core. Writes the signals from the TCQE board in the core to the TCRA board in location four for the core to control the gas manifold blow-off valve control.
• JS1 - Connects relay outputs from TCRA to DTBC/D terminal board.
• JS2 - Connects relay outputs from TCRA to DTBC/D terminal board. TCRA not connected to DTBC in
• JS3 - Connects relay outputs from TCRA to DTBC/D terminal board. TCRA not connected to DTBC in
• JS4 - Connects relay outputs from TCRA to DTBC/D terminal board. TCRA not connected to DTBC in
• JS5 - Connects relay outputs from TCRA to DTBC/D terminal board. TCRA not connected to DTBC in
• JS6 - Connects relay outputs from TCRA to DTBC/D terminal board. TCRA not connected to DTBC in
• JS7 - Connects relay outputs from TCRA to DTBC/D terminal board. TCRA not connected to DTBC in
• JS8 - Connects relay outputs from TCRA to DTBC/D terminal board. TCRA not connected to DTBC in

TCA CONTACT OUTPUT CIRCUITS:

The relays on the TCRA boards are operated by signals from the control sequencing program and sent to the STCA board over the COREBUS to the I/O Engine in the and cores. The STCA boards read the signals and write them to the TCDA boards via the IONET. The TCDA board then writes the command signals to energize the relays via the JO connector. Once the relay has performed its command (open/close) the action is written to the DTBC and DTBD terminal boards via the JS1 through JS8 connectors. These output signals are used by the process.
