Two power feeds and a light that tells you one has failed. The UPC-309R is built for lines that cannot be stopped to change a power supply: it takes redundant DC inputs, raises a warning light when one feed drops, and keeps running on the other. It is also the widest-rated member of the family at 0–70 ℃, and it carries up to six RS232 channels (two switchable to RS485), M.2 NVMe plus mSATA storage, HDMI 4K and VGA dual display and dual Intel i211 Gigabit LAN.

Design notes
Why two power feeds and a warning light pay for themselves

Redundant power with a light that tells you before the line stops
The UPC-309R accepts two DC power feeds and carries a warning light that indicates when one of them has failed. That turns a silent single point of failure into something a technician can see on the panel: the machine keeps running on the healthy feed, and the failed supply is replaced at the next planned window rather than during an unplanned stop. For a line that runs three shifts, the difference is between a service task and a production event.
- Redundant DC input — the box keeps running on either feed
- Warning light shows a failed supply before anything stops
- Supply changed during planned maintenance, not during a stoppage
- 12V DC on a 2-pin Phoenix connector (9–36V optional)
- Fanless, with no power-supply fan to be the item that fails first
Rated to 0–70 ℃, the widest in the family
Most industrial PCs in this range are specified for 0–50 ℃ with an extended option. The UPC-309R is rated 0–70 ℃ as standard, with storage from −25–60 ℃. That rating is what makes it usable in an unventilated cabinet, next to a heat source, or in a plant room where the ambient temperature follows the process rather than the air-conditioning schedule — the environments where an ordinary box PC starts to throttle or shut down in the afternoon.
- 0–70 ℃ operating range as standard
- Storage rated −25–60 ℃, with extended options available
- Suits unventilated cabinets and heat-adjacent installations
- Fanless aluminium chassis — no filter, no fan to seize
- 300 × 160 × 50 mm, 3.2 kg, wall bracket or VESA mount


Six serial channels and two storage devices on the same box
The power side is not the only thing this model is built for. It carries up to six RS232 channels on DB9 — two of which can be configured as RS485 — with 5V or 12V signalling, so a station can poll a whole bank of instruments and controllers from one computer. Storage is M.2 NVMe plus mSATA: the NVMe device for the system and the application, the mSATA device for data or as a second, independent volume. Networking is dual Intel i211 Gigabit LAN.
- Up to 6× RS232 on DB9, 2 switchable to RS485, 5V/12V
- M.2 NVMe + mSATA — fast system volume, separate data volume
- 4× USB 3.0 + 2× USB 2.0, HDMI 4K and VGA dual display
- 2× Intel i211 Gigabit LAN, Wi-Fi 802.11a/g/n, optional 4G
- Standard build C8.03.03.044: i5-10210U, 16GB, 512GB SSD

FAQ
UPC-309R frequently asked questions
Questions about the redundant power feeds and the warning light, the 0–70 ℃ operating range, the six serial channels, the M.2 NVMe and mSATA storage pair and the 300 × 160 × 50 mm chassis.
What does the redundant power input on the UPC-309R actually do?
It accepts two DC feeds and keeps the box running on whichever one is healthy. When a feed fails, a warning light on the unit indicates it, so the failure is visible before it becomes a stoppage. In practice the box is wired to two independent supplies — typically two feeds from the same panel or one feed plus a DC-bus source — and the faulty supply is replaced at the next planned maintenance window.
Do I need two separate supplies to use this model?
No. It runs perfectly well on a single feed; the second input is what gives you the redundancy. Many installations start with one supply and use the second input later, or run the second feed from a different distribution board so that a single breaker or PSU failure cannot take the machine down. The warning light works in both cases and shows the state of the supplies.
What is the operating temperature range, and why does it matter?
The {model} is rated 0–70 ℃ with storage from −25–60 ℃, which is the widest range in the family. It matters in cabinets without ventilation, in plant rooms where the ambient temperature tracks the process, and in installations next to ovens, presses or drives. An ordinary 0–50 ℃ box in those places throttles or shuts down in the afternoon; this one is specified for them.
How many serial devices can it drive?
Up to six. The chassis provides 6× RS232 on DB9, and two of them can be configured as RS485 for multi-drop buses, with 5V or 12V signalling support to match the devices already installed. That is enough for a bank of instruments, a set of legacy controllers and a bus of meters on one computer, with the six channels polled in parallel rather than through converters.
How is the storage arranged?
Two devices: M.2 NVMe plus mSATA. The NVMe drive is the fast volume for the operating system and the application; the mSATA drive takes the data, the archive or a second independent volume, which keeps a continuous logging workload away from the boot device. Memory is a single DDR4 SO-DIMM socket up to 16GB.
Which 10th Gen builds does the redundant-power box offer?
Three on the Intel® Core™ 10th Gen platform: i3-10110U at 2.10–4.10 GHz, i5-10210U at 1.60–4.20 GHz and i7-10510U at 1.80–4.90 GHz. The i5-10210U build with 16GB and a 512GB SSD is the configuration the datasheet numbers — C8.03.03.044; the other two builds have their part numbers issued per configuration. The redundant power hardware, the six serial channels and the chassis are the same in all three.
What display outputs does the redundant-power model provide?
1× HDMI up to 3840 × 2160 @24Hz and 1× VGA up to 1920 × 1080 @60Hz, driven simultaneously, plus line-out audio. Keeping VGA alongside HDMI means the industrial monitors and KVMs already installed in a plant room continue to work without an adapter, which matters when the replacement box is going into an existing panel.
What are the physical dimensions and mounting options?
300 × 160 × 50 mm and 3.2 kg net, or 337 × 160 × 53.2 mm with the mounting bracket. The front panel is high-strength aluminium alloy and the finish is black. It mounts on a wall bracket or a VESA plate, and the 50 mm height keeps it inside standard cabinet depths.
What approvals and customisation does the redundant-power model offer?
Certification is CE / RoHS, and the platform supports Windows 7, Windows 10 and Linux. Custom services cover custom BIOS, system encryption and custom LOGO, and Wi-Fi (802.11a/g/n, 2×2 antenna, 2.4/5 GHz) plus optional 4G are available alongside the two Intel i211 Gigabit ports.
