Features:
- Converts Mark V LM digital output commands into isolated relay contacts for field circuits.
- Uses a 30-relay standard population with a distinct four-relay Q11 location-four arrangement.
- Routes command input through JO and switched outputs through JS1 to JS5.
The board separates the command side from the terminal-board side, allowing a missing instruction and a failed field path to be traced from different connection points.
Two TCRA positions in each digital core divide the available contact outputs, so the physical slot determines which numbered circuits are present on one board.
Wetted power on J19 and J20 belongs only to particular location-five arrangements and should not be assumed on every relay-output position.
Apter Power supports post-EOL purchasing enquiries for General Electric DS200TCRAG1A Relay Output Board and can provide the applicable technical file.

DS200TCRAG1A Population by Position
- Standard population: A full board carries relays K1 through K30 for grouped contact outputs.
- Core quantity: Each Mark V LM digital I/O core uses two TCRA board positions.
- Q11 exception: Location four in the Q11 core contains four relays rather than the normal thirty.
- Position identity: Relay count and assigned output numbers must be matched to the original core and slot.
Command Sources Reaching DS200TCRAG1A
- TCDA source: Normal digital-core positions receive relay open and close commands from TCDA through JO.
- TCQE source: The four-relay Q11 location-four board receives its JO commands from TCQE.
- Input check: A missing command at JO belongs upstream of the relay board and its terminal connections.
- Relay response: A valid JO command with no contact change narrows the fault to the selected relay or board-side output path.
Field Connections from DS200TCRAG1A
- JS groups: JS1 through JS5 divide the switched relay outputs into terminal-board cable groups.
- DTBC route: Selected board positions deliver their contact outputs to a DTBC terminal board.
- DTBD route: Other positions use DTBD, including the location-five wetted-output arrangement.
- AC feed: J19 and J20 can provide 120/240 V AC to outputs 47 and 48 in the supported Q11 or Q51 location-five positions.
Position-Dependent Output Boundaries
- Solenoid sourcing: Permission to use relay groups as solenoid power sources depends on the installed core and board position.
- Q21 restriction: The first 18 DS200TCRAG1A outputs in the Q21 core cannot use the solenoid-source arrangement.
- Wetted contacts: J19 and J20 apply only to location five in the Q11 or Q51 core, not to every TCRA board.
- Circuit assignment: Outputs 47 and 48 may feed ignition transformers where the cabinet design assigns that duty.
