Siemens 403-2B 02.88 Control Circuit Board Card

Siemens 403-2B 02.88 Control Circuit Board Card is a compact, 16-point printed circuit board designed for use as a control interface within Siemens automation hardware. Identified by the 403-2B part number paired with the 02.88 revision, this card is cataloged as a Siemens PCB circuit board with a sixteen-point footprint suitable for integration into compatible control systems. As a discrete circuit board component, it serves to connect and route multiple control signals within a Siemens installation, particularly in legacy equipment that uses the 403-2B/02.88 module family. Market listings and second-hand inventories commonly reference the model as a Siemens 403-2B 02.88 16-Point PCB Card, signaling its role as a dedicated card rather than a general-purpose circuit board. When sourcing for older Siemens workflows, buyers typically seek this card to restore or maintain control pathways in legacy gear and ensure continued operation of the associated control architecture.
