802.11a High Power Industrial Hotspot RLX2 (FCC)


Discontinued: No new product for sale. More Info
Recommended replacements: RLX2-IHNF-E

The 802.11a High Power Industrial Hotspot™ (RLX2-IHA) is a high-speed wireless Ethernet radio for long range applications up to 5 mi. / 8 km. The RLX2-IHA uses the 5 GHz band and supports a data rate up to 54 Mbps. The radio features Ultra-Fast access point switchover times of less than 10 ms, which is ideal for applications such as automated storage-retrieval systems, automotive skillet lines, and bottle filling machines.

The radio will be appreciated by both sides – OT and IT. Your OT personnel will like the radio’s EtherNet/IP embedded object and Modbus agent support, which allows them to get diagnostic data into their PLC immediately, where they can analyze and act upon data, optimizing your resources. IT departments will appreciate the radio’s SNMP support.

Caractéristiques Avantages

  • EtherNet/IP™- or Modbus®-based PLCs/PACs can use message instructions to read diagnostic information from the radios, helping to reduce down time when troubleshooting wireless network problems.
  • 802.11i, WPA-2 Personal/Enterprise using 128-bit AES encryption ensures secure networking
  • RADIUS security ensures secure networking with advanced authentication and encryption
  • Virtual Local Area Networks (VLAN) allow for secure network segmentation
  • Network Address Translation (NAT) lets machine builders deploy many machines without needing to change IP addresses every time.
  • Quality of Service (QoS) provides data prioritization for I/O control devices, video data, etc.
  • Ultra-Fast Roaming (under 10ms) maintains seamless, high-speed connections to one or more devices on moving equipment and machines (such as cranes, AGVs, and carriers) as they travel between Access Points
  • IGMP Snooping & Packet Filtering optimizes UDP multicast traffic for superior EtherNet/IP I/O communications
  • Supports the ability to communicate with multiple Ethernet devices when used with existing third-party wireless infrastructures
  • Supports Power over Ethernet (PoE) to reduce cabling costs
  • Disaster recovery feature allows the radio configuration to be stored on a microSD card for quick field replacement
  • Connect serial networks (Modbus, DNP 3, etc.) over 802.11 wireless networks
  • Simple local and remote configuration, monitoring, and wireless network diagnostics via IH Browser utility or SNMP
