GE DS200RTBAG2AFB Relay Terminal Board – Reliable field I/O relay interfacing for Mark V and GE drive systems
The GE DS200RTBAG2AFB is a relay terminal board designed to bring clean, reliable relay interfacing to GE Mark V, drive, and excitation control cabinets. From my experience, the G2 variant typically uses low-voltage DC relay coils and provides dense, field-wirable terminals so you can switch external loads while keeping the controller side isolated. You might notice that OEMs favor this board when they need rugged, serviceable relay outputs with straightforward wiring and minimal fuss during commissioning.

Application Fields
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
One thing I appreciate is how quickly technicians can fault-find with this board. A maintenance lead told us, “We swapped the DS200RTBAG2AFB during a planned stop, transferred the field wires, and were back online in under an hour—status indication made it simple.”
Advantages & Value
- 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.
Installation & Maintenance
- 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.
Quality & Certifications
- 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
Commonly Paired GE Components
- 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.
