The HMIBP0DB5001A is a Box PC from Schneider Electric's performance line, carrying the full description HMIPCCB1B5CB40N04N00 and configured with 5 expansion slots. It was designed as a panel-mount industrial computer for HMI and SCADA runtime applications, handling data logging, recipe management, and direct machine control through its fieldbus interfaces.
The manufacturer has marked this unit as Obsolete.
The 5-slot passive backplane accepts PCI and ISA cards from the original generation. If you are migrating a legacy line, the mounting cut-out and power supply (24 VDC typical for this class) are the same as the later Magelis iPC series, but the slot pinout and BIOS-level differences mean a drop-in swap is unlikely without a runtime re-image. No need to gut the whole panel — the form factor fits the same panel cut-out, but the OS image and card driver stack will need updating.
