Use the full DCO01 P37511-4-0369666 identification when reviewing a replacement. Connector appearance alone does not confirm cable type, port assignment or project configuration.
Use the verified ABB reference groups below when checking the rack position, serial-port assignment and project configuration.

DCO01 P37511-4-0369666 provides four configurable serial interfaces for ABB Freelance rack-system process stations, giving the installed station dedicated channels for communication with supported serial devices.
For each channel, DCO01 P37511-4-0369666 can use RS-232C, RS-422 or RS-485 electrical signaling. The connected cable establishes the interface standard; there is no interface-selection jumper to change on the module.
When replacement or relocation is planned, verify DCO01 P37511-4-0369666 against the removed unit’s full part number, rack position, serial-port assignments, cable type and Freelance project configuration. ABB permits installation in the central unit or an I/O unit, but the documented station arrangement should be retained unless the engineering design is intentionally revised.
