WiFi Relay with Analog to Digital Conversion WiFi Relay with UXP Expansion Port WiFi Relay with XR Expansion Port

Onboard analog to digital conversion is available on selected models of these controllers! This will allow you to:

  • Read light and temperature levels
  • Easily activate relays when A/D limits are reached
  • Detect audio levels in a room when connected to a microphone
  • Read switches, potentiometers, and analog joysticks
  • applications are limitless, and surprisingly easy to integrate
  • Available on select boards

UXP is a new standardized data port, specifically for the purpose of speaking to various expansion modules. If the controller you are considering is equipped with a UXP port, you can take advantage of extended commands to speak to our growing line of I/O expansion modules. UXP in the part number allows you to:

  • Add Contact Closure Inputs
  • Add Analog to Digital Inputs
  • Add Voltage Detectors
  • Digital Potentiometer Outputs
  • Available on select boards

Models with the ProXR suffix will feature the ProXR commend set. The ProXR series will allow you to:
