Are you getting the most out of your Relay Contact Life??
Understanding the fundamentals of using a suppression diode not only keeps you and others safe, but can also protect the relay contacts from the high voltage arc.

We get alot of phone calls about surge suppression and the use of a suppression diode. As one of our FAQ, we thought we would share this summary from AutomationDirect. The following PDF is intended to give a quick overview of the negative effects of transient voltages on a control system and provide some simple advice on how to effectively minimize them. The need for transient suppression is often not apparent to the newcomers in the automation world. Many mysterious errors that can afflict an installation can be traced back to a lack of transient suppression. It also serves as a handy reminder that all AutomationDirect PLCs some with free manual downloads and many support documents.
