issues?

Reviewer: from UNIVERSITY PK, IL US

I had to replace the transistors with PNP type to get it to work. Relays will trigger when pins 1, 2, 3 or 4 are shorted to ground.

issues?

Reviewer: from Quakertown, PA

Just wanted to know if anyone had any issues with this kit. I ordered two and had problems with BOTH. 2 of the relays were short between C and NO. I also believe there are errors in the directions as neither of my kits functioned properly. I wound up using the remaining relays on a blank board and created my own card.
