Buzzp,
I can agree with your comment about the diode. Although I have two other designs that basically use the same protection circuitry. It is a design suggestion by the manufacturer found in one of their application notes on page 9.

Everyone,
Thank you to everyone who has continued to try and help me resolve my problem. I have been unfortunately distracted from my project due to a death in the family.
Buzzp, I appreciate your response. I would very much appreciate it if you could possibly look at my PCB layout and give me...
Laffalot,
Thank you for all of your input. I really appreciate it. I would like to reply to some of your inquiries and possibly give you some further information. In response to your suggestions above:
1. Yes, I am using a diode across the relay coil. I was not sure of the total power capacity...
I have a PCB based AC motor controller. The motor control is simply two on-board relays (for bi-directional AC motor) that simply turn on and off via a microcontroller. The reason a relay was chosen was to give as much isolation as possible between AC and DC. The board also uses a small...
I am looking at engineering a short range transmitter receiver combination, but I do not have any RF design experience to speak of. I know of a couple of companies (RF Monolithics and Linx Technologies and probably more) offer canned RF devices that make the actual RF design portion of the...
