Anything that switches or is switched by a digital signal. The eight inputs read pushbuttons, limit and level switches, proximity sensors, relay contacts and pulse outputs; the eight outputs drive lamps, indicator stacks, relays, contactors, solenoid valves and signal inputs on other equipment. Because the block is exposed over MODBUS, the logic that reacts to those signals can live in the box itself or in an existing PLC or SCADA master.

The box appears to the control system as another MODBUS node. The PLC, remote I/O coupler or SCADA master polls the UPC-209B registers exactly as it polls its other stations, reads the eight inputs and writes the eight outputs. Nothing proprietary is involved, and the existing program does not have to be rewritten — which is why this box is usually bought for a retrofit where the I/O has to be added without touching the controller.

Because logging and traceability stations outgrow a single drive quickly. The {model} provides an M.2 slot and a full-size mSATA slot, so the operating system and the application can live on one device while the data, images or archive live on the other — with capacity from 128GB to 1TB. Keeping them apart also protects the system volume from a logging workload that writes continuously.

The {model} carries 3× RS232 on DB9, and two of the three can be configured as RS485 instead. All three support 5V or 12V signalling, which is the practical detail that decides whether an existing serial device can be wired directly. Use RS232 for point-to-point instruments and legacy controllers, and the optional RS485 channels when a multi-drop bus of meters or sensors has to run on one twisted pair.

195 × 160 × 42.8 mm and 1.7 kg — the smallest form factor in the family, with a bracket version at 272.6 × 160 × 46 mm overall. It is the model for machine-mounted applications, small panels, kiosk back-boxes and retrofit cabinets where depth is the binding constraint. The front panel is high-strength aluminium alloy and the finish is black; mounting is by wall bracket or VESA plate.

Three on the Intel® Core™ 10th Gen platform: i3-10110U at 2.10–4.10 GHz, i5-10210U at 1.70–4.40 GHz and i7-10510U at 1.80–4.90 GHz. The i3-10110U build with 4GB and a 256GB SSD is the standard configuration — C8.02.03.004; the other two builds have their part numbers issued per configuration. Memory is a single DDR4 SO-DIMM socket up to 16GB.

The chassis provides 8 digital inputs and 8 digital outputs as one MODBUS block. If an installation needs more points, the usual answer is a second box or an external MODBUS I/O coupler on the same bus — the box already speaks the protocol, so adding points is a bus decision rather than a chassis decision. CESIPC can also discuss custom I/O configurations under the ODM service.

12V DC on a 3-pin Phoenix connector, with 9–36V DC optional for DC-bus cabinets and vehicle installations, and a power switch with AT or ATX startup mode. The wide input range matters in practice because field supplies sag under load; the box keeps running while a nominal 12V rail drops well below it.

It is fanless — nothing to filter, nothing to seize. Operating temperature is 0–50 ℃ with an extended temperature option available, and storage is rated −20–70 ℃. Certification is CE / RoHS. Custom services include 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.
