ACCUTRAC UE90121 Electronic Circuit Board

ACCUTRAC UE90121 Revision B circuit board is a replacement electronic PCB identified by model UE90121, offered in used condition and cataloged under stock number 8201. The unit is described as Rev B with serial numbers 9602A and 96041, and is listed by Conversion Devices Inc in the circuit boards / PLCs & accessories category, signaling its role as a spare component for ACCUTRAC equipment rather than a complete system module. Some marketplace listings also show a new version of the same Rev B UE90121 circuit board (often labeled with the designation #169210), indicating availability of unused variants in parallel markets. This part serves as a direct replacement for compatible ACCUTRAC assemblies where UE90121 is specified, enabling restoration of control functionality without the need to replace the entire device.
