EPC-W2122B · BlockCore™ Panel PC · GPIO
Most HMIs Just Show Data.
This One Controls Your Line.
The EPC-W2122B is a 21.5-inch industrial panel PC with 8 digital inputs and 8 digital outputs built in. It reads your sensors. It triggers your relays. It runs your HMI software. All from one device — no external I/O module required.

The Typical Setup — and What It Costs You
Picture a standard machine control panel. There is a panel PC showing the HMI. Next to it — or behind it, or tucked somewhere in the cabinet — there is a separate I/O module handling the digital signals: the sensors telling you a part is in position, the relay firing the reject gate, the indicator light on the door.
That setup works. It also means two power supplies, a communication cable between devices, a driver stack to maintain, and an extra device to source when something fails on a Friday afternoon.
For small-to-mid-scale automation — 8 sensors in, 8 outputs out — that added complexity is unnecessary. The EPC-W2122B handles both jobs from a single enclosure.
“Eight inputs, eight outputs, 24V — built into the panel PC itself. The operator sees the HMI; the machine feels the I/O. Same device.”
Three Places This Changes How You Build
An operator stands at the line. The 21.5-inch screen shows production status, batch counts, and alert messages. Behind the glass, DI channels are reading a photo sensor confirming part presence and a door interlock switch. DO channels are pulsing the reject solenoid and lighting the stack-full warning tower. No second device. No USB bridge to the I/O box. The wiring goes straight into the GPIO terminal block on the back of the panel PC.
A packaging machine, assembly station, or inspection line. The EPC-W2122B sits front and center. RS-485 reads parameters from a servo drive or temperature controller. GPIO reads the emergency stop and the feed-jam sensor. The screen gives the operator a live view of the process, and lets them change recipe settings — no separate HMI terminal, no add-on I/O board.
A distribution cabinet or building automation node. One LAN port connects to the building management system. The other runs a dedicated Modbus TCP loop to energy meters. RS-485 reads HVAC controllers. GPIO drives relay outputs for circuit breakers and lighting groups. The screen shows consumption curves, equipment status, and alarm history — without a separate SCADA box.
What Makes It Work in a Real Factory
A panel PC with GPIO is only useful if it keeps running. The EPC-W2122B is built for exactly the conditions that break consumer-grade hardware:
Fanless aluminum chassis. The most common mechanical failure in industrial PCs is the cooling fan. Remove it, and you remove that failure mode entirely.
9–36V DC wide-range input. Factory power is never perfectly clean. The EPC-W2122B absorbs voltage swings that would crash a standard system.
On sudden power loss, CESIPC’s SafeCore circuit writes a clean system state before voltage drops below threshold. Auto power-on recovery brings the system back without anyone touching it.
Dust-tight and protected against direct water jets. The 6H glass surface resists scratching from gloves, tools, and daily wipe-downs in harsh environments.
BlockCore™: Built to Outlast One Machine Generation
OEM machine builders face a specific problem: a machine designed today will be built and serviced for 8–12 years. The panel PC inside it needs to survive processor EOL, I/O requirement changes, and customer-specific customizations — without the machine being redesigned from scratch.
BlockCore™ is CESIPC’s answer. The compute core (i-Core board), I/O expansion (i-Function board), and connectivity layer (i-Connect board) are separate modules that share a common backplane. Need a faster CPU for the next machine generation? Replace the i-Core. Need additional serial ports for a new peripheral? Swap the i-Function board. The 21.5-inch display, the enclosure, the touchscreen — they stay.
