        Overview Manuals Sensor Channels Shaft Assignment Input Scaling Output Paths

        Features:

        • Extends the Mark V analog I/O set with vibration, position and key-phasor processing.
        • Allows the first three proximity channels to be reassigned for accelerometer inputs.
        • Combines hardware-jumper selections with I/O configuration constants for sensor scaling.
        DS200TCQBG1B serves the TCQB function across the R, S and T processor arrangement rather than operating as a terminal board.

        The vibration group covers eighteen proximity inputs, followed by ten position channels and two key-phasor inputs within the documented allocation.

        Sensor type, shaft assignment, sensitivity and diagnostic limits are defined in the I/O configuration, with PRX01-PRX03 also governed by board jumpers.

        GE has ended Mark V production; Apter Power may still coordinate DS200TCQBG1B support.

        TCQB Input Allocation

        • Vibration: Eighteen proximity channels cover shaft-vibration feedback.
        • Position: Ten inputs are assigned to axial position or differential expansion.
        • Phase Reference: Two key-phasor inputs provide rotational reference points.
        • Optional Feedback: The TCQB allocation can include six LVDT/LVDR inputs.

        Rotating-Train Mapping

        • Valid Codes: HP, IP and LP identify the high-, intermediate- and low-pressure shafts.
        • Filter Reference: Each vibration input is filtered against its assigned shaft speed.
        • Unused Entry: A double dash marks a channel without a shaft assignment.
        • Accelerometer Rule: PRX01-PRX03 use the unused shaft entry when configured as accelerometers.

        Configuration Values

        • Probe Sensitivity: Enter the proximity-transducer nameplate sensitivity for voltage scaling.
        • Position Offset: Position channels require the configured mechanical offset.
        • Diagnostic Window: Low and high voltage limits determine out-of-range alarms.
        • Speed Maximum: Accelerometer setups use power-of-two HP, IP and LP speed limits above expected shaft speed.

        Regulator and Sensor Interfaces

        • Milliamp Channels: Two regulator current outputs are assigned to the TCQB function.
        • Sensor Power: The Mark V interface supplies -24 VDC to proximity transducers.
        • Device Selection: Hardware jumpers distinguish proximity probes from accelerometers on channels one through three.
        • Configuration Match: Board settings and I/O constants must identify the same connected device type.
        Description
        General Electric DS200TCQBG1B is the TCQB RST extended analog I/O board used in the SPEEDTRONIC Mark V control processors. It adds sensor and regulator paths beyond the primary TCQA analog functions.

        For shaft monitoring, General Electric DS200TCQBG1B processes eighteen proximity-transducer vibration inputs, ten axial-position or differential-expansion inputs and two key-phasor channels. Each proximity transducer receives a -24 VDC supply from the Mark V interface.

        The first three feedback positions on General Electric DS200TCQBG1B can accept either proximity probes or accelerometers. The selected device type must agree in the I/O configuration and in the board's hardware-jumper positions, while the assigned HP, IP or LP shaft determines the speed reference used for filtering.

        General Electric DS200TCQBG1B also supports optional LVDT/LVDR feedback and two regulator milliamp outputs in the documented TCQB allocation. Sensor sensitivity, position offset and low/high diagnostic limits are entered as configuration values rather than assumed from the replacement board.

        Technical notes

        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 can General Electric DS200TCQBG1B report an incorrect vibration level after probe replacement?
        Confirm the new probe's sensitivity in the General Electric DS200TCQBG1B configuration and verify that the channel is assigned to the correct HP, IP or LP shaft.
        What must change when PRX01 is converted to an accelerometer on General Electric DS200TCQBG1B?
        Set both the device-type constant and the matching hardware jumper on General Electric DS200TCQBG1B, then remove the shaft assignment for that channel.
        How should a missing axial-position signal be separated from a vibration fault on General Electric DS200TCQBG1B?
        General Electric DS200TCQBG1B allocates position inputs after the eighteen vibration channels, so inspect the position channel's sensitivity and offset rather than the vibration scaling.
        What can cause repeated out-of-range alarms on an otherwise connected General Electric DS200TCQBG1B channel?
        Compare the configured low and high diagnostic limits on General Electric DS200TCQBG1B with the probe's actual voltage range before replacing hardware.
        Which details should be preserved when replacing General Electric DS200TCQBG1B?
        Record the General Electric DS200TCQBG1B sensor assignments, jumper choices, sensitivities, offsets and diagnostic limits because those settings define how the field devices are interpreted.
        Why is a key-phasor input not interchangeable with a normal vibration channel on General Electric DS200TCQBG1B?
        General Electric DS200TCQBG1B reserves two channels for rotational phase reference, while the eighteen vibration inputs measure shaft motion and use different scaling behavior.
        How can loss of proximity-probe excitation be investigated around General Electric DS200TCQBG1B?
        Check the -24 VDC sensor supply and field termination associated with General Electric DS200TCQBG1B before changing its software scaling values.
