Opto Isolation Module – 4 Channel


Package Includes

  • 1x 4-Channel Opto Isolation Module

Availability: 24 in stock

A 4 channel opto isolation module which uses PC817 optocouplers to optically isolate each of the 4 channels. Extremely useful when you need to protect your microcontroller from unruly voltage spikes and other potentially damaging anomalies. It can also be used to shift the voltage level of signals if required.
