If you need to expand the digital input of your VINT Hub, this module provides four extra inputs at minimal cost. Switches, buttons, or any device with a logic-level output can be read by these inputs.
If you need isolation, compatibility with higher voltages, or more digital inputs per VINT port, have a look at the “Other Digital Inputs” tab for more options. If you plan on counting pulses on a high-frequency signal (faster than 500 Hz) or to measure pulses shorter than 2ms in length, you’ll want to use one of our specialized frequency counter Phidgets instead.
