Key Features
Built for industrial deployment
Industrial Serial I/O
Four RS-232 COM ports (COM1–COM4) with standard DB9 pinout. COM1 supports RS-232/422/485 switchable via BIOS for PLC and sensor integration.
Dual Independent Display
LVDS 18/24-bit single/dual channel for embedded panels plus HDMI 1.4 for external monitors. Both outputs can run simultaneously at independent resolutions.
Dual Intel GbE
Two independent Intel GbE controllers (i210 + i211) for network redundancy, VLAN separation or OT/IT bridging without an external switch.
Flexible Storage Options
One mSATA slot and one SATA III port for SSD or HDD. mSATA accepts standard half-size and full-size modules for compact solid-state deployments.
Wide-Range DC Input
Single 12 V DC input via ATX connector. Accepts standard 12 V industrial PSU or DC-DC converter. Reverse-polarity protection on the power input circuit.
Applications
Where the IN-35-45U is deployed
Kiosk & Panel PC
Compact footprint and LVDS output make the IN-35-45U a natural fit for self-service terminals and industrial panel PCs.
HMI Controllers
Four COM ports and dual GbE allow direct connection to PLCs, sensors and SCADA systems without an additional I/O board.
Machine Vision
Dual display output supports simultaneous live feed and operator interface on a single board.
Industrial Gateway
Dual Intel GbE enables OT/IT network separation or bridging in a small 3.5-inch form factor.
Medical Devices
Low 15 W TDP and fanless-capable design suit sealed medical enclosures where noise and contamination are concerns.
Transportation
Wide-temperature operation and vibration resistance support in-vehicle and trackside computing applications.
