Overview
The HMIBMPSI74D4801 is a Schneider Harmony iPC modular box PC, order code HMIBMPSI74D4801, classified as the Performance main type with 8 GB DDR3 RAM and 512 KB MRAM internal memory, running on a 24 V DC supply. It measures 254.0 mm wide by 205.74 mm high, supports flat, wall, or book mounting, and offers four expansion slots: one PCI, one PCI Express 4x, and two mini PCI Express full-size.
As a Performance-class box PC in the Harmony iPC range, the HMIBMPSI74D4801 runs Windows 10 and hosts the HMI/SCADA runtime — EcoStruxure Operator Terminal Expert or Machine SCADA Expert — on its 8 GB DDR3 RAM. The 512 KB MRAM retains critical process data across power cycles without battery backup. Expansion is handled through one PCI slot, one PCI Express 4x slot, and two mini PCI Express full-size slots, plus two internal SATA bays for hot-swap RAID using the slide-in HMIYMADSDD1 and Intel Rapid Storage Technology. A CFast slot and an mSATA slot add further storage flexibility. The unit drives displays up to 3200 x 2000 pixels at 60 Hz via the integrated Intel QM87 chipset, and includes a watchdog timer configurable from 1 to 255 ms for application-level fault recovery.
Applications
Harmony iPC box PCs of this class serve as the central compute node for machine-level HMI, SCADA front-ends, and edge analytics in industrial automation — packaging lines, material handling, water treatment skids, and discrete manufacturing cells where a panel-mount display is paired via the HMIDM modular display range.
