PRODUCT HIGHLIGHTS
EPC-309A · Eleven Core Features
From core compute to industrial-grade protection — every design choice serves a clear purpose.
Dual Intel I210 + PTP
Dual Intel I210 Gigabit NICs with PTP clock synchronization — matched to industrial cameras and multi-device coordination for low latency, low packet loss and stable transmission.
Rich Industrial I/O
4× USB 3.0 + 2× USB 2.0 + 4× RS-232 + 2× RS-485 + 2× GbE + HDMI + VGA + audio. Multi-COM extended chassis.
Mini-PCIe Wireless Expansion
1× Mini-PCIe slot with optional dual-band Wi-Fi / Bluetooth / 4G / 5G modules, flexibly adapting to on-site networking.
9-36V Wide-voltage Phoenix Terminal
A 3-pin pluggable Phoenix terminal with 9-36V DC wide-voltage input. Four-way protection against over-voltage, over-current, reverse polarity and surge — easy and secure wiring.
FlexCore™ Modular Hardware Architecture
Built on the FlexCore™ four-element architecture: i-Core compute + i-Function expansion + i-Connect I/O + Smart Thermal control. Unified interfaces, structure and power with free expansion — a platform approach that cuts repeated development and maintenance costs.
Fanless Cooling
One-piece die-cast finned cooling in 6061 high-strength aluminum alloy with zero moving parts — maintenance-free, dust- and vibration-resistant, for industrial endurance.
SafeCore™ Industrial Reliability Enhancement
Four protection mechanisms working together: ① power protection (over-voltage / over-current / reverse polarity / surge) + ② backup power (smart lithium-battery power-loss buffering) + ③ start/stop control (auto power-on when energized) + ④ system self-recovery (watchdog + fault restart).
Hardware-level Auto Power-on
An independent power-logic circuit triggers the power-on signal, without relying on the BIOS. It restarts automatically once power is restored, keeping unattended deployments running continuously.
IP65 Front Panel + Aluminum
6061 high-strength aluminum alloy + sheet-metal structure for an industrial-grade rugged body. The IP65 front panel resists dust and splashing water, with TPM 2.0 + watchdog for dual security.
Multi-OS Support
Windows 10 / 11 · CentOS · Ubuntu 16.04 / 18.04 / 20.04 / 22.04. BIOS supports customization, boot logo and OEM branding.
