| Great question! I love that you're diving into the details with this setup. The 500 ohms relay coil and 125 mA current definitely need some careful consideration when you're working with 110V DC. It’s smart to think about how to get the right resistance in place. Keep up the good work! I would like to contact private security companies now because I have to hire an unarmed guard. |
