Wx100 PLC is TRi's latest generation of all-in-one full-function mini PLC with incredible amount of capability. Designed to bring modernity and affordability to even the smallest and simplest industrial equipment or automation projects, Wx100 makes available to any equipment it controls, 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 User Manual)

Any piece of equipment controlled by a Wx100 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 family and open your eyes to what is possible for your equipment - you will be glad you did!
