راهنمای جامع فایروالهای صنعتی و تقسیمبندی شبکه OT
فایروالهای صنعتی نقش حیاتی در امنیت سایبری OT ایفا میکنند و از شبکههای PLC، DCS و SCADA از طریق بخشبندی، کنترل ورود/خروج و ادغام IDS/IPS مطابق با اصول IEC 62443 محافظت میکنند.

The RLX2-IHNF-W-A (RLX2IHNFWA) is a hardened industrial wireless hotspot developed by ProSoft for outdoor automation networks. The unit delivers 802.11 a b g n wireless connectivity inside an IP67 weatherproof enclosure designed for harsh industrial environments. Engineers deploy this hotspot in oil terminals, mining conveyors, water treatment facilities, and remote substations where wired Ethernet installation is impractical. The die cast aluminum housing resists vibration, dust, and moisture while supporting pole mounting. Three external N type antenna ports allow directional or sector antenna configuration. The device operates across extended temperature ranges and maintains reliable wireless communication for mobile equipment, SCADA connectivity, and distributed control systems.
The RLX2-IHNF-W-A uses an industrial grade wireless radio supporting 2.4 GHz band communication. The design includes three N connector antenna interfaces for diversity and extended coverage deployment. The sealed enclosure meets IP67 protection requirements and supports outdoor pole mounting. Internal surge protection protects the radio from lightning induced transients. The device accepts wide range 10 to 24 VDC external power and integrates industrial temperature rated components. FCC compliant radio output ensures stable communication in regulated installations. The unit supports high speed wireless bridging for PLC, RTU, and remote I O communication.

Is RLX2-IHNF-W-A suitable for outdoor installations?
Yes. The IP67 die cast aluminum enclosure protects against water, dust, and harsh weather environments.
Can this unit connect to PLC or SCADA networks?
Yes. The device provides wireless Ethernet connectivity for PLC, RTU, SCADA, and remote I O communication.
What antenna types can be used with this hotspot?
The unit supports external N connector antennas including omni directional, sector, and directional panel antennas.
Does the device support wide temperature operation?
Yes. The hotspot operates from -40 to 75 deg C for outdoor industrial installations.
Mount the unit on a grounded metal pole using the integrated mounting bracket. Ensure the enclosure remains vertical to maintain antenna radiation pattern. Avoid mounting near large metal structures that block RF coverage.
Use outdoor rated coaxial cable between antenna and device. Keep cable length as short as possible to reduce signal loss. Tighten N connectors using proper torque to prevent moisture ingress.
Supply regulated 10 to 24 VDC power using shielded industrial cable. Connect earth ground to the enclosure grounding point to improve surge protection in lightning prone areas.
