Semiconductor P23-020 P2.15.100 Power Source Module

The Semiconductor P23-020 P2.15.100 Power Source Module is a dedicated power source unit used in legacy Semiconductor PLC backplanes, manufactured by Semiconductor Circuits. The device is identified by multiple catalog references, including P23-020 and P2.15.100, and is listed by some distributors as PA23-020. As a Power Source Module, it is intended to provide the required power delivery to other modules within an AB rack, supporting the operation of I/O, control, and communication cards housed in the chassis. This model appears in distributor catalogs and surplus listings under the Semiconductor Circuits brand, confirming its role as a compatible replacement part for AB systems that rely on a P23-series power source. When sourcing this part, verify compatibility by cross-referencing the P23-020 or PA23-020 identifiers with the target AB chassis and backplane configuration to ensure the power delivery characteristics align with the installation’s requirements. This description reflects the core identity and use case of the module for technicians and buyers working with older Semiconductor equipment, emphasizing the exact part numbers and brand to aid accurate replacement and repair decisions.
