Introduction 

The AWK-1127 WLAN client is ideal for industrial hard to wire applications, keeping wireless costs under control, and integrating with existing mobile equipment. The AWK-1127 enables WLAN connection to Ethernet devices, and offers an additional serial port for serial device connectivity. The AWK-1127 is rated to operate at temperatures ranging from 0 to 60°C for standard models and -40 to 75°C for wide temperature models, and is rugged enough for any harsh industrial environment. Installation is easy, with either DIN rail or wall mounting capability, wide operating temperature ranges, and IP30 housing with LED indicators make the AWK-1127 a convenient yet reliable solution for any industrial wireless application.

Critical Elements of Industrial-Grade Wireless Devices

 

Industrial operators using commercial-grade wireless devices for mission-critical wireless applications may be getting satisfactory wireless network service, but frequent maintenance and system downtime can add up to a high total cost of ownership. In this paper, we reveal many harmful effects commonly found in industrial environments that can quickly disable a commercial-grade wireless device, and discuss the types of protection an industrial-grade wireless device should provide to ensure continuous wireless network communication...more
