Overview 
The AWK-3121 Access Point/Bridge and AP Client is ideal for applications that are hard to wire, 
too expensive to wire, or use mobile equipment that connects to a TCP/IP network. The 
AWK-3121 can operate at temperatures ranging from 0 to 60°C for standard models and -40 to 
75°C for extended temperature models, and is rugged enough for any harsh industrial environment. 
Installation is easy, with either DIN-Rail mounting or wall mounting in distribution boxes. The 
DIN-rail/wall mounting ability, wide operating temperature range, and IP30 housing with LED 
indicators make the AWK-3121 a convenient yet reliable solution for any industrial wireless 
application.
