The Thermocouple Termination Module (TBQA) is located in the and cores. The TBQA terminal board lands the thermocouple inputs. The 90 terminal points relate to 45 thermocouple signals landed on the TBQA board. In the core, 15 signals (thermocouples #1 through #15) are written to the TCQA board in the core, 15 signals (thermocouples #16 through #30) are written to the TCQA board in the core, and 15 signals (thermocouples #31 through #45) are written to the TCQA board in the core. The TBQA board in the core has 42 possible thermocouple signals and they are all written to the TCCA board in the core. The TBQA board also provides the cold junction circuitry for the thermocouples.
