Each unit is function-checked before shipment and packed for industrial environments.
Relay-based isolation – Protects the controller by switching field loads via onboard relays, reducing noise coupling.
G2 coil profile – In many cases, G2 boards are matched to 24 VDC relay coils, simplifying common power bus designs.
Field-ready terminals – Screw or clamp terminal points for quick panel wiring and service work.
Status indication – Typically includes visual indicators (per relay or group) that make troubleshooting much faster onsite.
GE DS200 form factor – Fits standard GE drive/Mark V cabinet layouts with proven mounting and connectors.
Serviceable design – Relays and terminals are accessible; technicians can swap components with minimal downtime.
Proven compatibility – Commonly paired with GE control cards to handle discrete outputs to valves, contactors, lamps, and interlocks.
| Brand / Model | GE DS200RTBAG2AFB (Relay Terminal Board) |
| HS Code | 8538.90 (Parts suitable for apparatus of headings 8535/8536/8537) |
| Power Requirements | Supplied by control system auxiliary power; G2 variants are typically 24 VDC for relay coils (verify per installation) |
| Dimensions & Weight | Standard GE DS200 terminal-board format; typically under 1 kg installed |
| Operating Temperature | 0 to 60°C typical control cabinet environment (non-condensing) |
| Signal I/O Types | Form C relay contacts (dry contacts) to field devices; discrete control inputs from the host controller |
| Communication Interfaces | No network port; uses multi-pin ribbon/backplane connectors to the GE control system |
| Installation Method | Panel/cabinet mounting with standoffs; field wiring to terminal blocks; mating harnesses to controller |
This board is widely used in gas/steam turbine auxiliaries under Mark V, medium-voltage drives, and excitation systems where discrete relay output is required. Typical jobs include:
Driving motor starters, solenoids, and contactors with clean isolation
Interlocking safety circuits and permissive chains
Lamp/annunciator signaling from controller logic
General-purpose switching of low to moderate loads in industrial panels
Reliability – Industrial relays with proven GE hardware layout; fewer nuisance trips in noisy cabinets.
Compatibility – Designed for GE DS200 ecosystems, reducing integration risk and on-site engineering time.
Serviceability – Clear terminal labeling and accessible components help keep downtime low.
Cost control – Using board-level relay isolation can be more economical than distributed relay modules scattered through the panel.
Technical support – We can assist with model checks (e.g., G1 vs G2 coil variants) to align with your cabinet power scheme.
Cabinet requirements – Mount on a flat, grounded backplate in a closed, ventilated control cabinet; keep away from moisture and conductive dust.
Wiring – Use appropriately rated conductors; segregate power and signal wiring; torque terminals per GE guidance; label all field circuits.
Power check – Verify the relay coil voltage for the G2 variant (commonly 24 VDC) before energizing; ensure the common/return is correctly referenced.
Safety – De-energize and lock out before servicing; discharge any stored energy; observe ESD precautions when handling the PCB.
Routine maintenance – Periodically inspect terminal tightness, clean dust with dry air, and function-test relays during scheduled outages. Firmware updates are not applicable to this passive relay board.
Manufactured to GE industrial standards; used within CE/UL-compliant control assemblies (compliance is assessed at the system level)
RoHS applicability may depend on production lot and region; most units for industrial service are built to robust material specs
Warranty coverage: 365 days from delivery
DS200SDCC series (Drive Control Card) – upstream logic/controller
DS200TBQG series (Terminal Boards) – complementary discrete I/O termination
DS200TCQ series (I/O interface boards) – ribbon-cable interfacing to the RTBA
If you’re replacing an existing board, share the full model string “DS200RTBAG2AFB” and your cabinet coil voltage so we can verify the match. From my experience, getting the coil variant right up front saves a surprising amount of commissioning time.
