Wx100 series PLCs are TRi's latest generation of all-in-one full-function mini PLC with incredible amount of capability. Wx100-ExtA is identical to the standard Wx100 except it includes a built-in external antenna. This allows Wx100 to be mounted inside a metal enclosure with the antenna mounted externally, which will eliminate potential signal loss from the enclosure. Mounting can be done via DIN rail using our DIN-KIT-0 kit.

Designed to bring modernity and affordability to even the smallest and simplest industrial equipment or automation projects, Wx100 PLCs make available to any equipment they control, a graphical OLED display, a 16-key tactile keypad, from 14 to more than 160 analog and digital I/Os, built-in RS485 and over-the-air, WiFi connectivity to the Internet. (For more info, please refer to the online Wx100 Series User Manual)

Any piece of equipment controlled by a Wx100-ExtA is by default IIOT ready! In the next few years your customers will increasingly demand that the equipment you build must be IIOT capable. So check out the Wx100-ExtA family and open your eyes to what is possible for your equipment - you will be glad you did!
