        Overview Manuals Input Expansion DTBA Link Test Groups Validation

        Features:

        • Adds the last 46 contact inputs to the TCDA board in a Mark V LM digital core.
        • Receives contact power through JY from the companion DTBA module.
        • Uses JRR as the common expansion-bank signal connection to TCDA.
        DS200DTBBG1A is the contact input expansion termination module for the Q11, Q21, and Q51 digital cores. It complements DTBA rather than duplicating the first input bank.

        BJ1 through BJ5 isolate input groups from the 125 V DC source for testing. JRS and JRT are normally unused.

        Contact-sense inversion is set in the TCDA I/O Configuration, allowing the logic state to follow the required failsafe convention.

        Continued purchasing and documentation support for the General Electric DS200DTBBG1A Contact Input Expansion Termination Module remains available from Apter Power after manufacturer End-of-Life (EOL).

All prices are shown in USD.

        Last 46 contact inputs

        • Expansion-bank assignment: DS200DTBBG1A carries the final 46 contact inputs associated with the TCDA board in the same digital core. These points follow the DTBA first bank in the controller input map.
        • JRR boundary: JRR is the shared signal connection for the expansion bank. A full-bank loss should therefore be separated from a single terminal failure by checking JRR first.
        • Channel alignment: Channel numbers, field conductors, and TCDA assignments must remain aligned when the expansion bank is reconnected.

        JY contact-power source

        • Upstream supply: Unlike DTBA, DS200DTBBG1A does not receive its 125 V DC contact power directly from TCPD. Its JY connector receives that supply from the companion DTBA board.
        • Fault boundary: This arrangement creates a useful fault boundary: healthy DTBA points with a dead DTBB bank direct attention to the JY path and the DTBB side of the circuit.
        • JRS/JRT boundary: JRS and JRT are normally unused and do not replace the JY operating supply connection.

        BJ jumper behavior

        • Expansion-bank isolation: BJ1 through BJ5 isolate groups of DTBB contact inputs from the 125 V DC source for testing. An open BJ group affects multiple points even when the field contacts and JRR cable are intact.
        • Return position: Record the initial jumper map before a test and restore every group to its recorded position afterward.
        • Residual point fault: If one point remains abnormal after the group supply is restored, test that field contact and conductor independently from the shared JRR path.

        Separating wiring from configuration

        • Fault layers: A missing physical state can originate at the field contact, the landed terminal, JY power, JRR connectivity, or the TCDA assignment. The pattern of affected points narrows the search.
        • Logical reversal: An input that changes but appears logically reversed calls for review of the TCDA sense-inversion setting, not an immediate change to terminal polarity.
        • Acceptance check: Validation is complete when every disturbed field contact produces the intended state at its mapped TCDA channel.
        Description
        General Electric DS200DTBBG1A is the DTBB Contact Input Expansion Termination Module installed in the Mark V LM Q11, Q21, and Q51 digital cores. It adds the final 46 contact inputs for the TCDA board in the same core.

        The expansion-bank signals leave DS200DTBBG1A through JRR. Its JY connector receives the 125 V DC contact-power source from the companion DTBA module, so the DTBA-to-DTBB link is part of the complete input path.

        Five BJ jumpers on DS200DTBBG1A isolate defined contact-input groups from the 125 V DC source during testing. JRS and JRT are normally unused in this arrangement.

        The TCDA I/O Configuration can invert the sense of individual DS200DTBBG1A inputs for the required failsafe behavior. This board provides the physical expansion termination layer while channel meaning remains tied to the installed wiring map and TCDA assignment.

        Technical notes
        DS200DTBBG1A terminates the last 46 contact inputs; JRR connects the bank to TCDA and JY receives its 125 V DC contact-power feed from DTBA.

        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 all DTBB inputs be lost while DTBA inputs remain present?
        DS200DTBBG1A receives its 125 V DC contact power through JY from DTBA. Verify that inter-board supply link before checking each expansion input separately.
        What should be checked when the entire expansion bank is missing at TCDA?
        Inspect JRR seating, orientation, and continuity. JRR is the common DS200DTBBG1A signal path to TCDA, so one connector problem can affect many channels.
        Why does one field contact show the opposite state?
        The TCDA channel may be configured with input-sense inversion for failsafe operation. Compare the I/O Configuration with the intended contact convention before moving conductors.
        How should BJ1 through BJ5 be handled during testing?
        Use only the group required by the documented test and record the original positions. Leaving a BJ group isolated removes its contact-power path and can resemble an input failure.
        What does a single unstable DTBB input suggest?
        Focus on the field contact, terminal pressure, conductor, and assigned channel. Shared JY or JRR faults usually affect a broader pattern than one point.
        Why can several adjacent inputs fail after a cable was disturbed?
        Adjacent losses can follow a common JRR cable group or connector seating problem. Compare the affected point pattern with the terminal map before replacing DS200DTBBG1A.
        How can the last 46 inputs be validated after reconnection?
        Exercise representative field contacts across the expansion bank, then confirm their assigned TCDA states and any configured inversion; test every disturbed point.
