ds200tcrag2a Relay output board

Part Number ds200tcrag2a Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockDS200TCRAG2A is a Relay Output Board manufactured by General Electric as part of the Mark V LM series used in gas turbine control systems. K1 through K30 relays are housed on the Relay Output Board (TCRA), which is part of the digital cores. In every digital IO core, there are two of these boards. Only four relays are present on the TCRA board in core location 4 and they are linked to the TCQE using the JO connector. In some applications, these relays are employed to activate the blow-off valves on gas manifolds. The entire complement of 30 relays is present in all other TCRAs. It is possible to arrange the first 18 relays on TCRA at location 4 to act as a power source for solenoids. This configuration is also possible for the TCRA board's initial 16 relays, which are located in location 5 of both the cores. Hardware jumpers on the DTBC and DTBD terminal boards are used to do this. On the TCRA board, position 5 of any or both of the power connections J19 and J20 can be used to wet- ted two extra contact outputs (#47 and #48). The DTBD board in one of the cores receives 120/240 V ac power through connectors J19 and J20 from the core. Usually, ignition transformers employ these signals. In the digital cores, the TCDA boards write the signals that instruct the relays to open or close to the TCRA boards. The TCQE board in the core is where the signals for the TCRA board in position four come from. You cannot configure the first 18 solenoid outputs to function as solenoid power sources. TCRA CONNECTIONS: JO - Writes the signals for Q11, Q21, and Q51 from the TCDA board to the TCRA board in location five. writes the TCDA board's signals to the TCRA board at position 4 of the Q21 and Q51 cores. controls the gas manifold blow-off valve by writing the signals from the TCQE board in the "R1" core to the "Q11" core's TCRA board at location four. JS1 - Relay outputs from the TCRA are connected to the DTBC/D terminal board. JS2 - Relay outputs from the TCRA are connected to the DTBC/D terminal board. JS3 - Relay outputs from the TCRA are connected to the DTBC/D terminal board. JS4 - Relay outputs from the TCRA are connected to the DTBC/D terminal board.JS5 - Relay outputs from the TCRA are connected to the DTBC/D terminal board. JS6 - Relay outputs from the TCRA are connected to the DTBC/D terminal board. JS7 - Relay outputs from the TCRA are connected to the DTBC/D terminal board. JS8 - Relay outputs from the TCRA are connected to the DTBC/D terminal board. JOR/S/T - Not commonly used. TCRA CONFIGURATION: HARDWARE: The hardware configuration for the DTBC and DTBD terminal boards, which powers the relays or converts them to solenoids, takes place at the terminal board level. SOFTWARE: The TCRA board has not been configured with any software. 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.RELAY OUTPUT BOARD
