Overview
The unit occupies a 2U 19-inch rack slot (482.6 mm wide, 88.9 mm high, 480.06 mm deep) and is rated IP40 for in-cabinet use. It carries CE, CSA, CULus, CCC, and EAC certifications, plus EMC compliance to EN 55011 Class A and FCC Part 15.
As a 2U rack-mount industrial PC, the HMIRXOHCA3W01 runs Windows 7 32-bit (WES 7 Premium) and is intended for HMI, SCADA, and data-concentration roles on the plant floor. The Intel dual-core processor handles operator-interface applications and light data logging without a dedicated graphics card; the integrated Intel HD Graphics drives up to 2048 x 1536 pixel resolution on a single display. Storage is split between one internal SATA3 slot and two hot-swap SATA2 trays, one of which holds the pre-installed 500 GB enterprise hard drive. The 2 GB of DDR3 RAM is the factory default; the Micro ATX motherboard accepts up to 32 GB across four slots, which matters for larger SCADA tag databases or multi-application runtime environments. Connectivity includes four USB 3.0 ports, two USB 2.0 ports, two Gigabit Ethernet ports, one VGA and one DVI video output, two COM serial ports (one RS232 fixed, one RS232/RS485 optional), plus audio line in/out. Three speed-controlled fans manage thermal load; the watchdog timer is configurable from 1 to 255 ms.
Applications
Harmony iPC rack PCs of this class are deployed as the central operator-interface or data-server node in industrial automation lines — packaging, material handling, water treatment, and discrete manufacturing cells. The hot-swap drive and redundant-fan cooling suit continuous-process environments where uptime matters; the 19-inch rack format integrates into standard control cabinets alongside PLC racks and network switches.
Within Schneider's Harmony iPC range, the HMIRXOHCA3W01 is the entry-level 2U rack PC — the Device Short Name is "Rack PC 2U Optimum." It targets applications that need a Windows-based HMI platform with moderate processing and memory, without the higher power budget or redundant-supply option of the 500 W siblings.
The HMIRXOHCA3W01 carries CE, CSA, CULus, CCC, and EAC certifications, and complies with the EMC and Low Voltage Directives (2004/108/EC, 2006/95/EC). No official end-of-life notification is recorded in the evidence; the part is treated as an active catalog item. Sourcing is via RFQ — confirm lead time and minimum order at time of quote.
