I would give this little device 10 Stars if it were allowed. This device does EXACTLY what I need it to do.
My application is to delay an external hard drive in docking station connected to a router to record videos and images from security cameras.
I have a sensor to monitor loss of internet connection. When this happens, modem and router are restarted.
The problem is that if you turn on the hard drive before the router is fully initiated, then the hard drive is not recognized by the router. Video/picture are no longer saved to hard drive because hard drive is not recognized by the router if hard drive powered up too soon.
By giving the hard drive about a 5 minute delay before powering up, it solves this problem perfectly. Router restarts and fully initiates, then 5 minutes later hard drive comes onlline and connects perfectly to the router making is accessible via the local network.
This device is inexpensive, yet works like a charm to solve a maddening problem.
I wired it into the system by purchasing a 2 ft extension cord from Amazon, cutting the black and white wires, but allowing the common to continue from end to end.
The black wire from the power source (110v plugin) was connected to terminals 12 & 14, tied together. The white from the 110v plug was connected to terminals 9 & 13, tied together.
On the other side (where the device is connected, (in my case hard drive) the black wire connects to terminal # 8 and white wire to terminal # 5.
If you want to protect from anyone touching exposed 110 volt terminals you can cover it with black silicon, again purchased from Amazon. That is what I did to make for a safer installation so you do not experience a shock should you accidently touch the open terminals.
Great Device. Could not be happier with my purchase.

Excellent problem solver for networking gear
The power went out a few weeks ago, and after 40mins or so the UPS shut everything down. The problem was that hours later when the power came back up, it all came up simultaneously whereas what I really need is the router to come up a few minutes AFTER the cable modem. This little relay has a knob on top to set the delay for anywhere from 0 to 10 minutes so that it all boots in the proper sequence and I can remotely monitor for when the house comes back online.
