4x Isolated Digital Input Phidget
Description
Add 4 isolated active-high digital inputs to your hub at the cost of only one VINT port.
Looking to add some serious digital inputs to your VINT Hub? This module has four active-high digital inputs ideal for reading switches, buttons, digital sensors, and other devices with a logic-level output. Each input can withstand up to 30V from the devices it's connected to, and they trigger faster than ordinary VINT digital inputs, making it more likely to trigger from very brief changes.
Isolated for Stability
The VINT port on this board is isolated from the digital inputs, improving stability by removing unintentional ground loops from the system. Each input is also isolated from one another, reducing the amount of cross-channel interference.
Other Options
If you need a module with more isolated digital inputs per VINT port, or if you want a simpler, more cost effective solution, have a look at the Connection & Compatibility tab.
