        Overview Manuals Event Timing Terminal Boards Redundancy Paths Relay Diagnostics

        Features:

        • Collects forty-eight grouped contact inputs and controls twenty-four relay outputs through one Mark VI VME slot.
        • Records contact transitions with 1 ms sequence-of-events timing for trip and permissive analysis.
        • Supports simplex or triple modular redundant paths with terminal-board identification and online diagnostics.
        TBCI boards bring the field contacts to J33 and J44, while two TRLY boards carry the commanded relay outputs through J3 and J4.

        A TMS320C32 I/O processor runs scheduled acquisition tasks and exchanges input, command, and health data with the Mark VI controller over the VME data path.

        Simplex projects can use DTCI and DRLY DIN-rail interfaces; TMR installations distribute the signal paths across the R, S, and T racks according to the approved control design.

        Apter Power supports sourcing for the General Electric IS200VCRCH1B VME Discrete Input/Output Board used in installed SPEEDTRONIC Mark VI systems.

        Sequence-of-events trail

        • Time resolution: Contact transitions are stamped to 1 ms.
        • Input scope: All forty-eight contact points can contribute event records.
        • Sequence review: The stamps help separate initiating trips from later shutdown feedback.
        • Controller context: Event data is transferred with the corresponding input state to the Mark VI controller.
        • Alarm correlation: When a permissive chatters or a trip chain changes unexpectedly, compare the IS200VCRCH1B event sequence with controller alarms before disturbing the field wiring.
        • Evidence quality: A reliable time trail depends on correct rack configuration, healthy excitation, and stable TBCI connections; timestamp evidence should therefore be reviewed together with the board diagnostics.

        Field-interface choices

        • Contact inputs: TBCI boards connect through the front J33 and J44 ports.
        • Relay outputs: Two TRLY boards connect through J3 and J4 for twenty-four commands.
        • Simplex alternatives: DTCI and DRLY DIN-rail boards are available for non-TMR layouts.
        • Excluded option: The VCRC implementation does not accept the point-isolated TICI board.
        • Identity check: Each terminal board carries identification data that the I/O processor compares with the downloaded hardware configuration.
        • Replacement trace: Before replacing IS200VCRCH1B, trace the installed cables and confirm the terminal-board catalog and revision rather than assuming that another VCRC-family interface is interchangeable.

        Signal-path organization

        • Simplex mode: One I/O path acquires contacts and drives the assigned relays.
        • TMR mode: Inputs and output commands are distributed across the R, S, and T racks.
        • Configuration control: Downloaded topology must match the connected terminal boards and cable positions.
        • Service boundary: Redundancy does not compensate for an incorrectly mapped field circuit.
        • Voting path: The installed architecture determines how contact states are voted and how relay commands reach the TRLY assemblies; it is not set by the replacement board alone.
        • Exchange control: For a controlled exchange, preserve rack position, connector assignment, and application configuration, then verify channel health after IS200VCRCH1B returns to RUN.

        Fault-isolation checks

        • Board state: Review RUN, FAIL, and STATUS indications after rack power is restored.
        • Communication loss: Relay outputs are designed to move to the de-energized condition.
        • Output path: Check the TRLY supply, fuses, command state, and relay feedback.
        • Input path: Correlate TBCI excitation and wiring checks with latched channel diagnostics.
        • Identity faults: Resolve terminal-board part-number or hardware-revision mismatches before service.
        • Corrective sequence: If the new board does not enter RUN, de-energize the rack before reseating IS200VCRCH1B and securing its captive screws and front-cable latches. Use the diagnostics to distinguish a field-side failure from an I/O-processor or communication problem before changing relay hardware.
        Description
        The General Electric IS200VCRCH1B VME Discrete Input/Output Board is a single-slot Mark VI I/O processor that acquires field contact states and issues relay-output commands through the controller's VME data path.

        Forty-eight grouped contact inputs arrive through TBCI terminal boards, while two TRLY boards provide twenty-four commanded relay outputs. Unlike the wider VCCC arrangement, IS200VCRCH1B performs this interface in one VME position and does not support the point-isolated TICI board.

        Simplex installations may use DTCI and DRLY DIN-rail interfaces, whereas TMR systems fan input and output paths across R, S, and T racks. Contact transitions are time-stamped to 1 ms, and identification data lets IS200VCRCH1B detect an incompatible terminal-board type, revision, or connector location.

        Within gas-turbine sequencing, IS200VCRCH1B can combine permissive and status inputs with relay commands used by auxiliaries and shutdown circuits. Online I/O configuration and diagnostic reporting support controlled maintenance without reducing the page to a list of disconnected specifications.

        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
        What terminal boards should be confirmed before replacing IS200VCRCH1B?
        Verify that IS200VCRCH1B is connected to TBCI and TRLY boards, or the intended simplex DTCI/DRLY interfaces; it does not support the point-isolated TICI option.
        Why can IS200VCRCH1B report a terminal-board incompatibility fault?
        IS200VCRCH1B reads each connected ID device and compares board type, hardware revision, and connector location with the downloaded configuration; correct the mismatch before returning the rack to service.
        How should missing contact transitions on IS200VCRCH1B be investigated?
        Review field excitation, TBCI wiring, the latched channel diagnostic, and the 1 ms event time stamps before concluding that IS200VCRCH1B itself has failed.
        Which wiring and redundancy details must be verified before installing IS200VCRCH1B?
        Yes. IS200VCRCH1B supports simplex or TMR architecture, but the terminal-board cabling and redundancy configuration must match the installed Mark VI arrangement.
        Which observations help diagnose a newly installed IS200VCRCH1B that stays offline?
        Power down the VME rack, reseat IS200VCRCH1B, secure its captive screws and cable latches, then restore power and review the RUN, FAIL, and STATUS indicators.
        Why might relay outputs associated with IS200VCRCH1B remain de-energized?
        Check communication to IS200VCRCH1B, TRLY supply and fuses, output commands, and relay feedback because the output path is designed to de-energize when communication is lost.
        Can IS200VCRCH1B configuration be adjusted while the Mark VI is operating?
        The Mark VI permits online I/O configuration and tune-up data for IS200VCRCH1B, but changes should be validated against the approved application and hardware before activation.
