I bought this for my x carve. I use it to control the vacuum and router . all you need to do is change the setting in machine setup to single spindle , hook up 2 wires to back of this unit , plug vaccume spindle into labled outlet. it's a real game changer. vaccume and spindle shut off during bit changes and when carve is complete. very high quality

At first couldn't get it to work. Thought it was defective. Fortunately it was all operator error.Now that is fixed....one touch control to turn on and off my processor and Crown amps....big smile 😊😊😁😁.Recommended.PS....Note it comes without written instructions.....there is a video on YouTube that shows how to proceed.

If you are looking to add this to your Langmuir MR-1 for flood coolant, the cable you also need to buy is called a GX-12. Two conductor version. Probably a three footer. Just plug the two wires into the connector and it will work perfectly. Polarity doesn’t matter. Did wish it had two screw mounts, it only has one.

Just got this hooked up to turn on my subwoofer and bias light when I turn on my tv. The tv turns on the avr via hdmi and the avr energizes a usb output, which I use as a trigger for the relay. Seems to work perfectly for my application.Couple of suggestions to improve the relay: as another reviewer said, mounting tabs on both ends would be nice, and the power switch could be moved over a bit or recessed so it doesn’t interfere if a large plug or transformer is plugged into the adjacent outlet.

I used mine to connect the 12 volt trigger from a WiiM Ultra streamer to a Son of Ampzilla amp (a vintage 70’s power amp with no power switch). It works perfectly! Amp turns on when the WiiM is turned on and turns off when the WiiM enters standby again. Since I can activate and control the WiiM with the WiiM Home app on my phone, I can completely control the system remotely. It even turns off automatically when no signal is detected for 2 minutes. I also plugged the power supply for my turntable into one of the switched outlets. The WiiM is powered from one of the “always on” outlets. This way, the entire system is powered (both switched and unswitched) from this unit.

The auto-on circuit of an older sub I own failed a number of years ago. The sub works fine after being power cycled, but will not turn back on after going into no signal standby. I finally got tired of moving the couch and power cycling the sub manually. I bought this power relay to use a 12v trigger from my AV processor to turn the sub on/off with the rest of my amps and speakers. Works great

The first thing to know about this unit is that it is well thought out to be versatile for any number of interesting projects. In my case it was recommended for use with an rPi Connected to the Internet which allowed remote control of a ham radio. Works perfectly.The unit has four US-style AC female outlets. One is marked always on and the power supply for the rPi is connected there. One is marked normally on, which I don't currently use since it will switch off when the unit is triggered. And the other two outlets are marked normally off. There is a small standard DC connector on the side ready for your wires, and which accepts a wide variety of DC inputs to trigger the relay that switches the unit. When DC power is applied to the relay, the normally off units turn on and then normally on unit turns off and the always on unit remains always on.For the DC input I use two pins off the rPI; the remote software has three sets of pinouts configured for an on off DC style switch. (With this third party software I can have up to three switches or devices with separate on/off.)Ham radio inside a building typically runs off of a physically separate power supply. Most of these are large beasts, sometimes with loud fans, and they draw a reasonable amount of power just sitting and get hot. So I connected the power supply AC cord to the switch. Now when I want to access my ham radio from a remote location I log into my software, and the first thing I do is actuate the ac power to the via radio power supply via the unit sold here. (Next, the software determines the state of the radio, turns it on now that the power supply is energized, and I can conduct my radio operations remotely from there).The really useful and important factor for me is that I can de-energize the radio power supply in addition to turning the radio off with its own on off switch.You may well think of 1004 other more creative uses for the unit. The important part is that it works well and seems to be solidly built, and definitely does the trick for me.ONE MINOR CAVEAT: Since I have the radio plugged into a "normally off" outlet, the only way to energize the radio outlet is via my remote software. It would be really helpful to have a momentary-press button available to actuate the relay manually at the unit as if it had been actuated by a DC input.But this is a minor quibble, and if I'm going to be away for a length of time, it isn't a problem because I don't have the need of the manual turn on of the power.

Works great to switch remote power amps for my 5.1 home theatre. Using a DC trigger from my Marantz pre-pro.

I have 3 of those now. So useful. I use them to turn on/off all my sound systems in the house.One wish, more normally off outlets or remove the normally on for a normally off.

I bought this to control the fans on my home theatre to be triggered by the 12v out on my receiver. It works perfectly. I only had to buy an mono plug that fit my receiver and connect the other end to this unit. The connector is a bit small, but it doesn't use a lot of current and works well. When my receiver switches on, it powers up the fan controllers that are plugged into it. It also as an always on and a plug that is reversed so that its off when my receiver is on and on when my receiver is off - I don't use that one, but its great to have the flexibility! Seems reliable, but I've only had it a few months. It is solidly built and was well packaged. I'd recommend if you have a similar need.

Many Bang and Olufsen owners like using older Bang and Olufsen receivers with non-B&O external amplifiers and other equipment. B&O is famous for the efficiency of its remote systems, and many like me would like to be able to power up an external amplifier when you use the remote to switch on the B&O equipment, and power off all together at the end of a listening session.There is a B&O box that can be found used, but it has the disadvantage of (in North America) being only 2-pin, and it is sensible to plug in a ground three-pin amplifier to a three-pin outlet.This relay box is more than an excellent alternative, and the outlets are grounded. It is easy to wire up to B&O equipment, and then works very well, the DC trigger voltage being well within the range for the Iot. The power rating is more than adequate, there are four useful outlets, and it takes up no more room that the B&O relay box.It is also good value.It neatly fulfills a hi-fi niche, and should be applicable to other stereo and hi fi uses where the equipment has a DC trigger voltage outlet, and you want to simultaneously switch on/switch off other equipment.
