It is a 12.5-inch industrial panel PC designed for air-conditioning control rooms and environmental monitoring. Instead of a general-purpose port set it carries what those rooms actually use: six isolated RS-485 trunks, four dry-contact inputs, two dry-contact outputs and a MODBUS interface — so one panel polls the plant room and joins the building management system as a node.

Because a plant room is six separate buses, not one. Chillers, air-handling units, VAV boxes, meters, sensors and the BMS gateway each tend to run on their own RS-485 trunk, and merging them means re-addressing equipment that is already commissioned. The panel also carries one isolated RS232 port for the older controller that never moved to a bus, two USB 2.0 ports and audio. Isolation is the second half of the answer: between two buildings or two risers there is often a ground-potential difference, and a non-isolated port is what fails when it appears.

The four inputs read switch-type signals — float switches, fan-proof and filter-differential contacts, door contacts, pump run-status relays. The two outputs drive annunciators, lamps or interlocks. They are wired to terminal blocks on the panel rather than through a separate I/O module, and because the whole set is exposed over MODBUS, the BMS or SCADA master reads and writes them the same way it handles any other node. The block is 4 inputs and 2 outputs, alongside six isolated RS485 ports and one isolated RS232 port.

The panel speaks MODBUS. The existing master polls its registers like any other station and sees the six RS-485 buses and the dry-contact block as data points. Nothing proprietary is involved and the BMS program does not have to be rewritten, which is usually why this panel is bought for a retrofit: the riser cupboard gets a display and an edge controller without touching the head-end configuration.

A 12.5-inch 16:9 TFT at 1920 × 1080, 300 cd/m² with 500:1 contrast and an LED backlight rated at 50,000 hours. Touch is projected capacitive, with resistive 5-wire available on request, and the front bezel is IP65 — a plant room is a dusty place, and the front can be wiped down without water reaching the electronics.

313.9 (W) × 199.8 (D) × 87 (H) mm with a cutout of 264.9 × 184.0 mm, weighing 2.9 kg gross. It mounts in the panel cutout, on a wall bracket or on a VESA plate. Cooling is completely fanless — no filter to clean and no fan to seize in a room that is normally unmanned.

The standard build is the Intel® Celeron® J1900 at 2.0–2.42 GHz with 4–8GB DDR3L and an mSATA SSD (part number C11.01.04.014) — a 10 W part, which is why this model runs cool in a closed cupboard. A Celeron J6412 build with DDR4 (C11.01.04.015) and a 12th Gen Core i3-1215U build with DDR5 and 2× M.2 SSD (C11.01.04.016) are available as platform options in the same cutout; CPU model may vary, so confirm the configuration with sales.

12V DC on a 3-pin pluggable terminal block, with 9–36V DC optional and an internal AT/ATX mode switch. Networking is 2× Intel I210 Gigabit LAN, with Wi-Fi (Intel N6235) and optional 4G LTE. Operating temperature is 0–50 ℃ as standard with −40–70 ℃ available; storage is −10–60 ℃ and humidity 10%–90% non-condensing.

CE and FCC according to EN 55032 and EN 55035 plus EN IEC 61000-3-2, from an ISO 9001:2015 factory with MTBF of 60,000 hours. ODM covers custom BIOS, boot-on-LOGO and OEM branding, and because the panel is a BlockCore™ platform the processor tier, the wireless options and the touch type are all set per order.
