Nice Apollo XBA3/U Control Board for M-Bar L-Bar Barrier Operators
The Nice Apollo XBA3/U is the electronic control board used in specific XBA3-style M-Bar and L-Bar barrier operator platforms. This is one of the parts where correct identification matters more than appearance, because control boards can share similar terminals or cabinet locations but have different receiver options, firmware, safety monitoring requirements, and production-date fitment. The XBA3/U version is commonly described as a no-receiver board and is tied to M-Bar / L-Bar barrier operators built before January 1, 2019. In the field, this board may be replaced after surge damage, failed inputs, no motor command, unstable programming, or damaged accessory terminals, but the cause of failure should be checked before installing a new board. Safety devices must remain connected and functioning after replacement.

Technician Note
This XBA3/U item should be matched to the installed Nice Apollo barrier operator and parts diagram. For M-Bar and L-Bar equipment, confirm the arm length, control board, cabinet style, and accessory requirements before replacing parts by appearance alone.
Before Ordering
- Confirm the full barrier operator model and arm family.
- Match the visible part number or parts diagram reference to the item being ordered.
- Check for related required parts such as XBA13 rubber strips, compatible control board, lid, arm section, or mounting hardware.
- Do not assume similar XBA part numbers are interchangeable.
- For electrical accessories or control board replacement, use a qualified gate technician if the system has unsafe wiring, missing safety devices, or high-voltage concerns.
Professional Advisory
Barrier arm systems are exposed to vehicle impact, weather, vibration, and frequent cycling. After replacing any arm, light, control, mounting, or traffic accessory, the installer should check arm balance, movement, clearances, safety devices, warning devices, and final operation before returning the lane to service.
Product Questions & Answers
Does XBA3/U include a receiver?
No. This row is for the XBA3/U no-receiver board version. Receiver requirements should be checked separately.
Which operators commonly use this board?
It is commonly referenced for M-Bar and L-Bar barrier operators using the XBA3/U control platform, especially pre-2019 MBAR/LBAR references.
Can this board replace a BCU1?
Do not assume that. BCU1 and XBA3/U references should be matched by the operator model, production date, and parts diagram.
What should be checked before replacing the board?
Check the board label, operator model, production date, connected accessories, safety devices, and wiring condition.
Can safety devices be bypassed during replacement?
No. Monitored safety devices and required entrapment protection must remain installed and operational. Use a qualified technician for high-voltage or unsafe conditions.
