OTIS SOM Group Control Board HAA26800AJ1 DAA26800CL1 CL2 CL3 CL4

OTIS HAA26800AJ1 and DAA26800CL1, DAA26800CL2, DAA26800CL3, and DAA26800CL4 are electronic board references used in compatible OTIS elevator parallel-control or group-control systems.

In the elevator spare-parts market, these products are commonly described as SOM parallel boards, group control boards, or elevator parallel-control PCBs. They are individual electronic assemblies rather than complete elevator controllers.

Confirm the Exact CL Version

The references CL1, CL2, CL3, and CL4 belong to the same general board family, but the suffix should not be ignored.

Before ordering, buyers should provide:

• complete HAA26800AJ1 or DAA26800CLx marking

• front and rear PCB photos

• connector quantity and arrangement

• shorting ring or jumper configuration

• removable components or plugs

• installation position inside the controller

• complete controller-cabinet photo

• elevator model or system information

• previous repair details

• site fault description

• quantity required

Some replacement-parts references distinguish DAA26800CL3 and DAA26800CL4 by the shorting-ring arrangement. CL3 is commonly listed with a shorting ring, while CL4 may be supplied without one. This detail should be confirmed from the original board rather than added or removed without technical verification.

Do Not Select the Board by Appearance Alone

Boards from the same SOM family may have a similar PCB outline while differing in:

• jumper or shorting-ring arrangement

• connector definition

• fitted electronic components

• hardware revision

• system configuration

• parallel or group-control application

• previous repair or modification

The safest method is to compare the complete original part number together with the connector layout and jumper configuration.

These boards may be investigated when technicians encounter abnormal communication between elevators, unstable parallel operation, group-control faults, damaged connectors, visible PCB failure, or problems identified during controller troubleshooting.

However, a group-control fault does not automatically mean that the PCB is defective. Technicians should also inspect the communication wiring, controller power supply, plugs, grounding, terminals, and connected elevator controllers before installing another board.

Programming, configuration, and functional testing should be completed by qualified elevator technicians. Communication between elevators, hall-call allocation, operating status, and related controller functions should be verified before the elevators return to service.

For maintenance companies in Saudi Arabia, Jordan, Egypt, Iraq, UAE, Kuwait, Brazil, Colombia, Spain, and Italy, clear old-board photos and close-ups of the shorting-ring and connector areas are recommended before shipment.

FAQ

What is HAA26800AJ1?

HAA26800AJ1 is commonly supplied as an OTIS SOM parallel or group-control board used in compatible elevator control systems.

Are DAA26800CL1, CL2, CL3, and CL4 interchangeable?

Not automatically. The complete board number, connector arrangement, shorting-ring configuration, hardware revision, and original control system should be checked first.

What is the difference between DAA26800CL3 and CL4?

Public spare-parts references commonly state that CL3 has a shorting ring while CL4 does not. The original board should still be photographed and verified before replacement.

Is this the complete group controller?

No. It is an individual PCB used within a compatible OTIS parallel or group-control system, not the complete controller cabinet.

What should I send before quotation?

Please send the complete board label, front and rear PCB photos, connector close-ups, shorting-ring or jumper area, controller-cabinet photo, and elevator system information.
