1018_3B Phidget InterfaceKit 8/8/8 , 1018_3B


The Phidgets workhorse. Connect sensors, control outputs, and read in digital inputs.


We have a limited supply of the new 1018_3B available.

Due to parts and components going obsolete and becoming unavailable, the 1018_3B has moved to a new processor that is not supported under Phidget21. If you're using our old libraries you must upgrade to Phidget22 before you can make use of this Phidget.

The 1018 PhidgetInterfaceKit provides 8 digital inputs, 8 digital outputs, and 8 analog inputs. This Phidget connects to your computer via USB.


  • Analog Inputs: measure the 0-5V signal produced by one of our many analog sensors
  • Digital Inputs: read the state of a switch or button
  • Digital Outputs: drive an LED, relay or transistor

Technical Details:

  • Adjustable data rate - Sampling intervals can be set as low as 1ms, or as high as 1 second.
  • Digital Input filtering - Hardware Filter eliminates false triggering from electrical noise.
