ASRock Industrial iEP-7040E-021 Intel Arrow Lake Core Ultra 7 255H DIN-Rail Industrial PC with PoE and 2.5GbE

IP cameras and small sensors near a machine often need power and data on one cable, and a separate PoE switch adds another box to the cabinet. The ASRock Industrial iEP-7040E-021 is the PoE build of the iEP-7040E series, with two IEEE 802.3af ports supplying up to 15.4 W each, so the fanless DIN-rail industrial PC can power those devices directly.

The Intel Core Ultra 7 255H is a 16-core Arrow Lake-H processor rated at 28 W, with Intel Arc graphics and an integrated NPU for dedicated AI acceleration, so the iEP-7040E-021 can run edge AI inference next to control, logging or HMI software. Two DDR5 5600 SO-DIMM sockets take up to 96 GB with Intel In-Band ECC, and an M.2 2280 Key M socket on PCIe Gen4 takes NVMe storage. ASRock Industrial supports Windows 11 and Linux.

In total there are five LAN ports: three Intel I226-IT ports at up to 2.5 Gbps and the two Intel I210-AT Gigabit PoE ports, which ASRock Industrial fits as a module in the M.2 Key B socket. The rest of the I/O covers one HDMI 2.0b and one VGA output, three USB 3.2 Gen 2 and one USB 2.0 port, three RS-232/422/485 ports, 4DI/4DO on a D-sub connector, and line-out and mic-in audio. An M.2 Key E socket takes an optional Wi-Fi and Bluetooth module, and a watchdog timer, Intel In-Band Manageability and TPM 2.0 are built in.

Power is 19 to 36 V DC, with an optional 330 W 24 V adapter, on two three-pin terminal blocks for redundant feeds, with over-voltage, under-voltage and over-current protection plus 80 V surge protection. The iEP-7040E-021 runs fanless from -25 °C to 50 °C with airflow, is tested to 5 Grms vibration and 100 G shock, and carries CE and FCC Class A marks. Mounting is wall or DIN rail. We supply it configured and tested, with memory, NVMe storage and the OS image fitted. The iEP-7040E-022 keeps five LAN ports without PoE, and the iEP-7041E-021 is the PoE build with a Core Ultra 5 225H.
