If you're evaluating industrial PCs for SCADA and edge control, the real question isn't just processor speed-it's whether the unit can connect to the wired and wireless field devices you already have. The NCD.io PR55-36_9HP Industrial IoT Edge Computer tries to answer that with a Linux compute module, a long-range Digi XBee radio, WiFi, and a populated SIM slot, all in a clear-lid enclosure.
Quick Verdict
At $375.00, this open-box industrial edge computer offers a practical starting point for remote monitoring and control. It includes the power adapter and both antennas, and the clear lid reveals the internal layout. It is not plug-and-play: the unit has been tested, may need basic software reinstalled, and a factory reset is recommended before deployment.
Who It Suits
This unit suits engineers and integrators who want a fairly open Linux-based edge computer with multiple wireless options and don't mind handling initial setup. If you need a pre-configured, fully documented system, the open-box condition and missing paperwork could be a drawback.

The listed configuration brings together an Onion Omega2S+ Linux compute module, a Digi XBee PRO S3B 900MHz radio, WiFi, an OLED display, Ethernet, an SD card slot, USB-A and USB-Mini ports, and a populated SIM card slot. That mix lets the unit act as a hub for long-range XBee nodes while also connecting to local IP networks and a cellular path through the SIM slot. The 6V-32V DC input range and -20°C to 70°C operating temperature give you flexibility for different power and environment conditions.
One concrete reason to choose it: the populated SIM slot and the XBee radio provide multiple connectivity paths without additional USB adapters. One limitation to keep in mind: this open-box unit comes without the original box or documentation, and the software state may require a reinstall and reset before you rely on it.
What Stands Out from the Listed Details
The clear enclosure lid is more than a cosmetic feature-you can visually confirm the radio, compute module, and wiring before applying power. Having both antennas included is also helpful, since wireless range depends on having the right antennas attached. The populated SIM slot means the hardware path for cellular is present, which is useful for edge deployments that use a cellular backhaul.
The 6V-32V DC input range is another practical detail because it covers common industrial supply voltages, and the -20°C to 70°C operating range is worth noting for installations in unconditioned spaces. The unit is marked RoHS compliant and made in the USA, so it fits into procurement environments that prefer those attributes.
Meaningful Trade-offs
The biggest trade-off is condition. This is an open-box, never-deployed unit, but some testing was done. There is no original box or documentation, so you'll need to rely on your own setup knowledge. A factory reset is recommended before first use, which might mean reinstalling basic software. Budget time for that.
In terms of pricing, the listed price is $375.00, and the ncd.io retail price is $459.95-an $84.95 spread. That gap reflects the open-box state, so you're trading a lower price for some setup and documentation trade-offs.
Bottom Line
If you need an industrial edge computer that can bridge XBee wireless nodes, WiFi, and a cellular-ready SIM slot, the NCD.io PR55-36_9HP is a strong candidate at $375.00. Just plan to reset the software and fill the documentation gap with your own notes. For integrators who already have a setup workflow, this multi-radio industrial PC delivers a lot of connectivity in one open-box package.
