Features:
- Scales additional analog signals received from Mark V I/O-core terminal boards.
- Applies LVDT/LVDR excitation and conditions servo-valve current commands.
- Terminates the protective and digital IONET chain at the applicable control core.
DS200TCQCG1B occupies the TCQC expander position in the R1, R2 and R3 analog I/O cores.
Its connectors divide servo traffic, pulse-rate inputs, power monitoring and generator feedback into distinct routes toward TCQA and STCA.
Hardware jumpers select servo-output current range, feedback scaling, proximity-supply limits and selected magnetic-pickup gain.
Because GE no longer manufactures Mark V, Apter Power may still assist with DS200TCQCG1B sourcing.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Regulator Output Control
- Current Range: The first sixteen jumpers select servo-output current and feedback scaling.
- Extended Range: Jumpers 25 through 36 add scaling choices for servos one through four.
- Clamp Relay: An emergency command can apply positive current to the servo valve.
- Suicide Relay: A control command can drive the signal to ground so the valve moves toward bias.
Speed and Flow Routes
- TBQB Source: JH receives magnetic-speed, TTL pulse and compressor-stall signals.
- QTBA Source: JGG accepts additional magnetic-pickup and megawatt-transducer inputs.
- TCQE Source: JJ receives high-pressure shaft speed signals originating at PTBA.
- Fuel Flow Gain: JP38 and JP39 set pickup gain for selected liquid-fuel-flow applications.
IONET Chain Endpoints
- R1 Chain: TCQC in R1 terminates the Q11 and P1 IONET path.
- Optional R2 Chain: A fitted Q21 chain terminates on the R2 TCQC board.
- JX Link: This connector receives the daisy-chained TCEA and TCDA network signals.
- STCA Transfer: 8PL forwards the IONET traffic directly to STCA.
Generator and Current Paths
- Sync Signals: Generator and line feedback is conditioned for the STCA synchronization check.
- Stall Input: One milliamp channel normally carries compressor-stall detection from TBQB.
- Power Input: The second milliamp path normally carries the megawatt-transducer signal from QTBA.
- Board Exchange: JE links TCQC with TCQA for power monitoring, servo outputs and generator/line signals.
