EPC‑W2122B Series — BlockCore™ Panel PC with GPIO FAQ
21.5‑inch industrial panel PC with 8DI/8DO configurable GPIO — 12th Gen Core, DDR5, 5 COM ports, BlockCore™ modularity, and SafeCore™ protection.
What makes the EPC‑W2122B unique?+
The EPC‑W2122B is a 21.5‑inch industrial panel PC with integrated 8DI/8DO configurable GPIO, purpose‑built for applications requiring direct digital I/O control without external PLCs or I/O modules. Standard industrial panel PCs lack built‑in GPIO, forcing users to add external I/O modules that increase cost, cabinet space, and failure points.
Key differentiators include:
• 8×Digital Inputs + 8×Digital Outputs (configurable 24V/12V/5V) — Integrated GPIO for direct connection to sensors, switches, relays, and actuators. Eliminates the need for separate PLC or I/O modules in many industrial automation applications.
• Intel® 12th Gen Core™ processors — i3‑1215U / i5‑1235U / i7‑1255U with DDR5 memory (8–32GB), delivering superior performance for edge AI, real‑time analytics, and multi‑stream data processing.
• 5×COM ports (3×RS232 + 2×RS485) — High serial density for connecting legacy PLCs, sensors, and industrial meters alongside the GPIO.
• 21.5‑inch 16:9 Full HD display — 1920×1080 resolution with 350 cd/m² brightness, 10‑point projected capacitive touch, and IP65 front panel protection.
• BlockCore™ modular architecture — Built on CESIPC’s BlockCore™ platform, supporting i‑Door expansion modules without custom PCB development.
• SafeCore™ power‑loss protection — Prevents OS/file corruption during sudden power loss with one‑reboot recovery, critical for unattended and mission‑critical installations.
Standard commercial panel PCs lack these industrial‑grade features — particularly the integrated 8DI/8DO GPIO — and would require external I/O modules, increasing installation cost, cabinet space, and failure points.
What is the advantage of integrated 8DI/8DO GPIO for industrial applications?+
The 8×Digital Inputs and 8×Digital Outputs provide significant advantages for industrial automation, machine control, and monitoring applications.
Key advantages:
• Eliminates external PLC/I/O modules — For many industrial applications, the integrated GPIO replaces the need for separate PLCs or distributed I/O modules, reducing system cost, cabinet space, and installation time.
• Configurable voltage levels (24V/12V/5V) — The GPIO supports multiple voltage levels, making it compatible with a wide range of industrial sensors, switches, and actuators without level shifters. 24V is standard for industrial sensors; 12V for automotive/transportation; 5V for TTL‑level logic.
• Direct sensor and actuator connection — Connect limit switches, proximity sensors, push buttons, and photoelectric sensors directly to the DI inputs. Control relays, solenoids, indicator lights, and small actuators via the DO outputs.
• Machine status monitoring — Monitor machine run/stop states, fault conditions, and alarm contacts directly through the digital inputs, eliminating the need for external monitoring hardware.
• Reduced latency — Direct GPIO on the panel PC provides lower latency than USB‑ or Ethernet‑connected I/O modules, critical for real‑time machine control applications.
Why choose the 21.5‑inch widescreen display?+
The EPC‑W2122B features a 21.5‑inch 16:9 TFT LCD with 1920×1080 Full HD resolution, 350 cd/m² brightness, 450:1 contrast ratio, and 50,000 hours LED backlight life. Standard touch is 10‑point projected capacitive; resistive touch is available for gloved environments.
Why 16:9 widescreen matters for industrial applications:
• Native SCADA/HMI compatibility — Modern SCADA platforms (Ignition, WinCC Unified, FactoryTalk View SE) are natively designed for widescreen formats. The 21.5‑inch 1080p resolution provides the ideal canvas for dashboards, process diagrams, and trend displays.
• Multi‑parameter visualization — The large widescreen display allows operators to view machine parameters, alarm lists, production dashboards, and GPIO status simultaneously without switching screens.
• Operator readability at typical viewing distances — The 21.5‑inch size is optimised for viewing at 0.5–1.5 metres (arm’s length to workstation distance), the typical range for a seated or standing operator at an industrial workstation.
• Panel‑mount compatibility — The cutout dimensions (516.6×308.1mm) match standard 21.5‑inch industrial panel cutouts, simplifying retrofit projects where existing displays need replacement without cabinet modification.
What processors and performance options are available?+
The EPC‑W2122B supports Intel® 12th Gen Core™ processors exclusively, sharing identical mechanical chassis, I/O layout, and mounting dimensions across all SKUs — simplifying spares logistics for large‑scale deployments. Options include:

Modular I/O via BlockCore™: The BlockCore™ platform supports additional expansion modules (i‑Door) for CAN, 5‑port LAN, isolated serial, and 5G without custom PCB development.
What is BlockCore™ modular architecture, and how does it benefit my deployment?+
BlockCore™ is CESIPC’s modular computing architecture that standardises interface, structure, power, and expansion across all products. For the EPC‑W2122B, BlockCore™ delivers:
1. Standardised I/O expansion (i‑Door) — i‑Door expansion slots accept function modules (CAN, 5‑port LAN, isolated serial, 5G, GPIO) without custom PCB development. For applications requiring CAN bus for robot integration or 5G for remote site connectivity, simply add the module — no hardware redesign.
2. LEGO MODE design philosophy — Based on modular construction principles, BlockCore™ creates an ecosystem where compute, I/O, and function boards can be configured like building blocks. This reduces custom development cost by up to 80% through standardised module libraries.
3. Shared ecosystem across product families — The EPC‑W2122B uses the same expansion modules as other BlockCore™ industrial PCs. Standardise spares across mixed fleets of panel PCs, embedded PCs, and network gateways.
4. Future‑proof upgrades — The BlockCore™ architecture allows future processor upgrades within the EPC‑W series without changing the I/O layout, GPIO, or mounting dimensions.
5. Extendable product lifecycle — BlockCore™ effectively extends product lifecycle, making investment in the EPC‑W2122B more cost‑efficient over the long term, particularly for large‑scale industrial automation rollouts spanning multiple years.
What protection does SafeCore™ provide for industrial deployments?+
SafeCore™ is CESIPC’s system‑level power‑loss protection architecture built into the EPC‑W2122B. In industrial automation and critical infrastructure environments, power interruptions are common — emergency stops, maintenance lockout/tagout, or voltage dips from welding robots and servo drives — events that can corrupt OS files and production logs if power is removed abruptly. SafeCore™ provides:
• System‑level write protection — Blocks all unauthorised changes to the system; even after power failure, user error, or malware attack, system files automatically restore after reboot. On the production line, this prevents data corruption that could halt production for hours while IT rebuilds a workstation.
• One‑reboot recovery mechanism — System crash or file corruption? Just reboot — the system returns to a healthy working state. No technical skills needed. Line supervisors or maintenance technicians can restore service in minutes without waiting for IT support.
• Zero IT support required — Anyone on the production floor can recover the system with a simple restart, reducing downtime and on‑call IT costs.
• Safe disk writes — Prevents fragmentation or file corruption during sudden power loss, ensuring data integrity for production logs, quality inspection records, and GPIO control states.
Combined with auto power‑on recovery (the system automatically restarts when power returns) and 9–36V DC wide‑range input (tolerates voltage fluctuations from industrial equipment), SafeCore™ ensures continuous operation even on electrically noisy factory floors. SafeCore™ is standard across all EPC‑W2122B models and works in tandem with TPM 2.0 hardware security for encrypted authentication and data protection.
