Relay expansion module issues

[mrrw60]

Has anyone experienced there relay expansion module making a loud clicking noise and causing all the devices plugged in to turn of then on by it's self. Seems like there is a constant loop because this happens every couple minutes. The relay expansion is new and installed last night.

No. I haven't.
Have you tried running the Relay test code that is in the sample codes?

Make sure all of your connections are solid as well.
