TLP281 4 CH Opto-isolator Expansion Board

(0)

This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system. This board electrically isolates a controller from the high-power system by use of an opto-isolator IC. This IC has four LEDs and four photodiodes built-in. This allows the low-voltage side to control a high voltage side We …
