Otis Elevator Board DBA26800EE2/10/14/15 – Quad-Logic Braking Intelligence for Gen2® & 4200 Drives | Nanjing Zhuye Elevator Parts
Hidden inside the drive cabinet, the Otis DBA26800 family does far more than “drop the brake”. Boards EE2, EE10, EE14 and EE15 form a modular safety chain: they switch the brake coil, monitor current feedback, verify lift-off voltage and report SIL-3 status to the controller in real time. When one fails you may see brake-sticking faults, unexpected emergency stops or the dreaded “Brake Lift Fault” on the HMI. Nanjing Zhuye Elevator Parts keeps genuine DBA26800EE2/10/14/15 units in anti-static packaging, pre-flashed with the latest firmware and ready for same-day despatch—helping you restore confident stopping without costly OEM delays.

-
4200/5200 high-speed gearless up to 4 m/s, 1 350 kg rating
-
Modernisation packages replacing obsolete DBA16700 or relay-based brake contactors
-
Any Otis controller expecting SIL-3 brake feedback and < 5 ms switch-off time
Installation method – 10-minute field swap
-
Place lift on inspection mode; stop at mid-shaft; switch OFF main breaker; lock & tag.
-
Wait 5 min for DC bus to discharge (< 50 V).
-
Photograph existing wiring; note brake polarity and CAN-FD plug.
-
Release two side latches; slide old board out of DIN rail.
-
Select correct mask: EE2 = standard, EE10 = ReGen, EE14 = high-speed, EE15 = fire-service.
-
Insert new DBA26800 board until latches click—no tools required.
-
Re-connect 24 V, 48 V brake lines, CAN-FD, relay feedback.
-
Power up; green “BRK” LED must illuminate within 3 s, “COM” LED blinks blue.
-
Launch Otis Brake Tool (OBT-15) on laptop; auto-test cycles brake 3× and records lift-off current.
-
Return to normal mode; log serial number and firmware v10.7 in maintenance book.
Replacement cycle & preventive maintenance
Although solid-state, brake boards live in a harsh world—coil surges, summer heat and voltage spikes. Otis bulletin SB-BRK-2024-02 recommends:
-
Visual inspection every 6 months: clean dust, check for burnt I/O terminals.
-
Brake current test: lift-off current must be within ±5 % of baseline; replace board if drift > 10 %.
-
Replace entire board every 10 years or 3 million brake cycles, whichever comes first.
-
Immediate replacement if:
– “BRK FAULT” LED red with car stopped,
– brake lift-off current reads 0 A after coil verification,
– relay outputs weld closed (contacts pitting),
– CAN-FD communication lost (blue LED dark).
Pro tip: 60 % of premature failures are traced to loose 48 V terminals—re-torque to 1.8 Nm every year.
Maintenance tips from Nanjing Zhuye Elevator Parts
-
Always use suppressor diode across brake coil; back-EMF > 150 V destroys output switches.
-
Never hot-plug I/O while lift is running; transients can weld relay contacts.
-
Keep a spare DBA26800 set in every service room; at 0.42 kg it fits in a pocket and saves a night call.
-
After lightning storm, check 24 V ripple < 1 V; high ripple overheats the DC-DC converter.
-
Order the “Brake Board Bundle” (EE2/10/14/15 + suppressor diode + torque tool) from Nanjing Zhuye Elevator Parts to eliminate parts hunting and ensure matched components.
Why buy from Nanjing Zhuye Elevator Parts?
We are an Otis-authorised distributor, importing DBA26800EE2/10/14/15 directly from the Czech factory, pre-loading firmware v10.7 and testing every unit on a 48 V brake simulator for 60 min under full load. Boards are shipped in anti-static foam with a 24-month replacement warranty. Our 3 000 m² Nanjing warehouse holds 150+ units year-round; orders placed before 15:00 China time leave the same evening via DHL Express, arriving Europe or North America in 2–4 days. Bulk pricing starts at three pieces; we can pre-select the correct mask and include a loaner board to keep your lifts braking during the swap.
Conclusion
The DBA26800EE2/10/14/15 board is the silent guardian that turns brake commands into safe, verified motion. By installing the genuine Otis unit, following the torque schedule and replacing it before relays age, you eliminate brake-sticking faults, unexpected stops and costly passenger entrapments. Stock genuine DBA26800 boards from Nanjing Zhuye Elevator Parts today—because when the brake brain fails, the whole lift stops.
