Features:

  • Relay interface: Organizes cabinet relay outputs on one serviceable board
  • Field termination: Provides defined connection points for external control circuits
  • Revision control: Requires the complete board marking and physical layout to agree
The board belongs to the host cabinet signal path and must be assessed with its power, control and field drawings.

Terminal numbering and relay grouping are the practical references for transferring conductors without changing circuit assignments.

A replacement is accepted only after connector fit, terminal mapping and controlled-load operation are verified.

Apter Power supports General Electric DS200RTBAG3A Relay Terminal Board sourcing with documentation and configuration review.
General Electric DS200RTBAG3A Relay Terminal Board Manuals,Datasheets,Link Important Notice: Confirm the full revision, cabinet drawing and field-terminal map before replacement.
  • Control boundary: Receives commands from the host control electronics and switches connected cabinet circuits.
  • Terminal map: Uses labeled connection points that must remain aligned with the site wiring schedule.
  • Host dependency: Relies on the installed cabinet for power, control signals and protection practices.
  • Drawing control: Cabinet schematics determine the correct interpretation of each relay and terminal.
  • Pre-removal record: Photograph both board sides, conductor tags and terminal positions before disturbing wiring.
  • Transfer sequence: Move one verified conductor group at a time against the approved terminal schedule.
  • Connector inspection: Check mating plugs, terminal hardware and contact condition before energization.
  • Circuit segregation: Keep control, supply and switched field wiring separated as required by the cabinet design.
  • Cold verification: Confirm label, connector orientation and terminal continuity before applying power.
  • Controlled energization: Restore cabinet power under the site procedure and monitor for abnormal relay operation.
  • Point test: Exercise each commanded output and confirm the intended field device responds.
  • Record update: Document the installed revision and final terminal map for future maintenance.
  • Drive auxiliaries: Routes relay-controlled auxiliary circuits in matching legacy GE drive cabinets.
  • Excitation support: Provides cabinet switching and termination where the installed excitation design specifies this board.
  • Outage replacement: Supports planned board exchange when wiring and revision records are available.
  • Legacy spares: Maintains an exact spare for sites operating the same cabinet arrangement.
Description
DS200RTBAG3A is a GE relay terminal board that concentrates relay switching and field termination functions within a matching legacy drive or excitation cabinet. It gives technicians a defined interface between cabinet control outputs and external circuits.

The operating value of DS200RTBAG3A depends on its installed connector pattern, terminal assignments and cabinet drawings. The board is not a standalone controller; it works as part of the host control assembly and its field wiring plan.

During a board change, DS200RTBAG3A should be matched by complete label, relay arrangement and terminal layout before conductors are transferred. A controlled point-to-point check and functional test then confirm that every switched circuit remains assigned correctly.

Technical notes
DS200RTBAG3A field wiring should be photographed and tagged before removal because a misplaced conductor can create a cabinet-level output fault even when the replacement board is electrically sound. Compare relay positions, terminal designations and mating connectors with the approved drawing, then verify each controlled load individually during recommissioning.

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.
Can DS200RTBAG3A replace a board with the same relay count but a different terminal layout?
A matching relay count is not enough. The connector positions, terminal numbering and relay arrangement should agree with the cabinet drawing before the board is selected.
What should a maintenance team record before moving field wires from DS200RTBAG3A?
Clear terminal photographs, conductor tags and a point-to-point list help preserve every circuit assignment during the transfer.
Why might a field device fail to respond after DS200RTBAG3A is installed?
A misplaced conductor, an unseated connector or an incorrect relay path can interrupt the output. Compare the commanded state with the terminal voltage and the cabinet schematic to locate the break.
How should DS200RTBAG3A be tested before the cabinet returns to service?
Begin with a cold check of the label, connector orientation and terminal continuity. Under the approved startup procedure, command each output separately and confirm that only the intended field device responds.
When is DS200RTBAG3A unsuitable for an existing GE cabinet?
It is not the recommended match when connector keying, terminal assignments, relay arrangement or the controlled revision differs from the installed design.
Which details help Apter Power quote DS200RTBAG3A for a planned outage?
The full board label, clear photos of both sides, the cabinet model and the terminal schedule allow a more accurate configuration review before quotation.
