Product Description:

The APC3100 is an industrial automation PC unit produced by B&R Automation and positioned within the APC Industrial Automation PC Units series. It acts as a controller-class computer that runs machine-level operating systems, gathers field data, and exchanges commands with drives, I/O, and safety hardware. Because it combines compute resources, communication ports, and solid-state storage in one enclosure, the device helps simplify cabinet layouts for packaging machines, assembly cells, and continuous-process skids.

The unit operates from a regulated 24 VDC ±25% SELV supply, tolerating typical DC-bus dips without rebooting. Its mainboard supports up to 32 GB of DDR4 SDRAM, allowing large code bases and data buffers to remain in memory. Two removable cards plug into the CFast sockets that are wired to a SATA III (6.0 Gbit/s) backplane, so image loading and log retrieval can complete quickly. The dual Ethernet controllers sustain a line rate of 1 Gbit/s, enabling real-time Industrial Ethernet protocols alongside standard TCP/IP traffic. For service or peripheral expansion, the USB connectors provide transfer speeds up to 5 Gbit/s when used with SuperSpeed devices.

At power-up, the APC3100 draws a surge of 60 A for less than 300 µs; once internal capacitors are charged, continuous consumption levels off at 5.5 A. Three option slots allow additional fieldbus or serial interfaces beyond the native dual Ethernet ports, and the SDL/DVI-D connector supplies video to a detached panel. The enclosure is rated IP20, so the unit must be installed inside a protected cabinet. USB outputs deliver 1 A each, and the total of 5 ports supports simultaneous programming, data logging, and peripheral connections. For nonvolatile storage, each of the two CFast locations accepts up to 256 GB per slot, allowing mirrored drives or separate system and user partitions without exceeding the onboard controller limits.
