PoOptoIn is 16 channel industrial digital optical isolator. It accepts 5-24V on input. On output it has Open collectors. When connected to 3,3V – 5V power supply, it’s output is logic 0 or logic 1. Signal LEDs are indicating status of each input. Each input is isolated from another.
If it is used with PoKeys57CNC, it can be directly connected to Limit/Home connector. Moreover limit and home signals from switches are opticaly isolated.
Using with PoKeys57E, PoKeys57U or any other microcontroller it effectivelly isolate up to 16 inputs with LED indication.
