        Overview Manuals Thermocouples Core Routing Cold Junction Fault Isolation

        Features:

        • Terminates Mark V LM thermocouple field circuits on three grouped connector paths.
        • Combines each temperature group with its associated cold-junction compensation signal.
        • Supports a 45-input R1 arrangement and a 42-input R5 arrangement without onboard jumpers.
        Because JAR, JAS, and JAT carry channel groups rather than isolated points, a connector-path fault can affect several temperature readings together.

        A group-wide offset can be separated from a single field-circuit problem by comparing the affected points with their shared cold-junction path.

        The core position determines whether the grouped signals terminate across TCQA boards or at TCCA, so the original cabinet route remains part of the board identity.

        Purchasing and document support for General Electric DS200TBQAG1A Thermocouple Termination Module remains available through Apter Power after manufacturer EOL.

        DS200TBQAG1A Channel Grouping

        • JAR group: Carries thermocouple channels 1 through 15 on the first grouped path.
        • JAS group: Carries channels 16 through 30 as the middle temperature-input group.
        • JAT group: Carries channels 31 through 45 in the R1 core, or channels 31 through 42 in the R5 core.
        • Compensation pairing: Each connector group travels with the cold-junction signal used for its temperature measurements.

        Receiving Paths for DS200TBQAG1A

        • R1 destination: JAR terminates at the TCQA board in the R1 core.
        • R2 destination: JAS from the R1 installation continues to TCQA in the R2 core.
        • R3 destination: JAT from the 45-input arrangement continues to TCQA in the R3 core.
        • R5 destination: JAR, JAS, and JAT from the 42-input arrangement all reach TCCA in the R5 core.

        Temperature Reference Behavior

        • Shared reference: DS200TBQAG1A adds cold-junction information to each grouped thermocouple path.
        • Common bias: Similar error across one connector group can originate in the compensation circuit shared by that group.
        • Single-point symptom: One abnormal channel is more consistent with its field pair or terminal than with a group-wide reference issue.
        • Path comparison: Comparing neighboring channels on JAR, JAS, or JAT helps separate sensor faults from common compensation faults.

        Tracing DS200TBQAG1A Measurement Faults

        • Group loss: Fifteen missing inputs direct attention to one grouped cable and its receiving-board path.
        • Core mismatch: Valid field signals appearing at the wrong controller points indicate that a grouped connector may be on the wrong core route.
        • No jumper layer: Board-level switch settings cannot correct a routing error because TBQA has no hardware jumpers.
        • Final proof: A known temperature or millivolt stimulus should appear at the intended channel with the associated cold-junction correction.
        Description
        In the Mark V LM analog section, General Electric DS200TBQAG1A serves as the TBQA thermocouple termination module, landing field temperature circuits and adding cold-junction compensation before analog processing.

        The DS200TBQAG1A position in the R1 core accepts up to 45 thermocouple inputs, while the R5 core position handles 42. These two placements use the same three connector groups but feed different receiving arrangements.

        On DS200TBQAG1A, channels are divided across JAR, JAS, and JAT. In the R1 installation the three groups reach TCQA boards in the R1, R2, and R3 cores; in the R5 installation all three groups reach TCCA in the R5 core.

        No hardware jumpers are fitted on DS200TBQAG1A. Its effective measurement path is therefore defined by the installed core, terminal assignments, connector grouping, and cold-junction connection rather than a board-level switch setting.

        Technical notes
        DS200TBQAG1A uses fixed JAR/JAS/JAT routing and has no hardware jumpers; document core position and cold-junction paths before disturbing thermocouple wiring.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Why would fifteen DS200TBQAG1A thermocouples disappear together?
        DS200TBQAG1A groups thermocouples on JAR, JAS, and JAT, so a shared cable or receiving-board path can remove an entire fifteen-channel group.
        What can cause a common offset across DS200TBQAG1A temperature readings?
        Because DS200TBQAG1A supplies cold-junction compensation with each grouped path, verify its cold-junction circuit and the related JAR, JAS, or JAT connection before recalibrating individual sensors.
        Why must the installed core be recorded before moving DS200TBQAG1A wiring?
        DS200TBQAG1A in R1 routes 45 inputs among three TCQA boards, while the R5 position routes 42 inputs to TCCA; the same connector name therefore serves a different core destination.
        Should hardware jumpers be copied when replacing DS200TBQAG1A?
        No. DS200TBQAG1A has no hardware jumpers; preserve the terminal map, board location, and JAR/JAS/JAT destinations instead of copying an unsupported switch setting.
        Why can a valid DS200TBQAG1A thermocouple appear in the wrong controller core?
        An exchanged JAR, JAS, or JAT cable on DS200TBQAG1A redirects a complete channel group to the wrong TCQA path even when the field sensor itself is healthy.
        What should be captured before disconnecting DS200TBQAG1A?
        Record the DS200TBQAG1A core location, every thermocouple terminal, polarity, connector label, and cold-junction path so the original channel grouping can be restored.
        How should DS200TBQAG1A be checked after wiring work?
        Apply a known temperature or millivolt stimulus to each disturbed DS200TBQAG1A circuit and confirm the intended channel and cold-junction-corrected value at the assigned TCQA or TCCA destination.
