Robertshaw N1-1048

Robertshaw N1-1048 is a Siebe Robertshaw printed circuit board (PC board) carrying alternate designations N100-781048 and RBSC-848-A, identified on product listings as a CSD PC Board with revision D. Within Robertshaw/Siebe burner-control and gas-appliance control architectures, this PCB serves as the central electronic platform that coordinates inputs from safety interlocks and sensors with generic control signals used by downstream actuators and subsystems. This part appears in Robertshaw cross-reference materials and service listings, which is common for legacy replacements and repairs on older gas-fired equipment. When sourcing the N1-1048 for repair or refurbishment, use the N1-1048, N100-781048, and RBSC-848-A CSD PC Board identifiers to verify compatibility with your unit's control module and harnessing, and engage a qualified technician to ensure safe and proper integration with the appliance's sequencing and safety logic. Because these boards were deployed across a range of Robertshaw modules, precise pinouts, connector types, and operating parameters can vary by application, so cross-checking against the appliance documentation is essential.
