Siemens PCB455-2 Printed Circuit Board

Siemens PCB455-2 Printed Circuit Board, revision 03.98, is a Siemens-branded printed circuit board identified by the part number PCB455-2, designed to serve as a component in Siemens automation and control assemblies that specify PCB455-2 in their documentation. The 03.98 designation indicates a particular revision level associated with Siemens' older hardware, and because exact electrical characteristics, connector configurations, and mounting footprints can vary by host system, it is essential to cross-reference the replacement with the equipment's service manual or a Siemens spare-parts catalog to ensure a correct fit. Installation should be performed by qualified personnel, following standard electronics-handling practices such as power-down and electrostatic discharge precautions, and if any doubt remains about compatibility, consult Siemens support or the equipment's manual to prevent misalignment or damage.
