O.C. COM on PSC28A

Postby twinsleong » Sat Jun 22, 2013 9:52 pm

Hello there. May I know what does the O.C. COM on PSC28A (PS2 I/O Converter) does?

From the applications in the user manual, it shows that it is connected to a 12V for relay connections.

Must it be connected to 12V only? Can we connect it to a 5V, 6V or even ground?

Never use that before, but from the User's Manual, it seem to use ULN2803 to control output. If you check the datasheet of ULN2803, there is a common pin, no.10. I think that is the pin being connected to the terminal O.C. Common. It depends on the output voltage you want to use. 5V is fine.

BTW, please put the link of product, is easier for us to find the product, not everyone is Cytron's staff.
