YFGW520 Field Wireless Access Point is based on wireless communications standard ISA100.11a for industrial automation of International Society of Automation (ISA). This product has backbone router function based on ISA, and combining this with Field Wireless Management Station (YFGW410) and/or Field Wireless Media Converter (YFGW610) composes the field wireless system.YFGW520 is a successor to YFGW510, enabling robust and longer distance backbone network construction.

· The high-performance industrial wireless relay device of the world's smallest class:
This product is an industrial wireless relay device of the smallest-in-the-world class based on multiple wireless standards. By that, this product expands a field wireless network, and provides reliable communication.

· Duocast (ISA100.11a Standard):
This product has a Duocast function of ISA100.11a standard. Reliability of the field wireless communication can be enhanced through receiving data simultaneously with two YFGW520s.

· Robust and plant-wide network:
YFGW520 supports two types of optical fiber communication option, makes it possible to construct a noise resistant and long distance (max 5 km) backbone network by combining with YFGW610.
