Power relay to control any 110v appliance

Power relay to control any 110v appliance
I control my condensation pump so if the pump fails, it shuts down my dehumidifier. It can be used on an ac unit also.It has 1 outlet always on, 1 normally on, and 2 normally off. So it can be used in numerous applications.

This is just the product I needed to automate a DIY cooling fan via the 12V trigger from my Onkyo A/V receiver. It is a nice, compact box that looks and feels very robust and durable with surprising heft for its size and the addition of a 3.5mm male mono jack to bare wire cable was all that was needed to get up and running in no time. This really is a terrific product for this price point ($25 at my time of purchase) and I doubt I could build one for less, but I do know that I can avoid possible electrocution by not trying to DIY something like this. I do have two complaints about this device, one minor and one not so minor. The minor gripe is the use of adhesive labels that curl up on the corners in lieu of printing the information directly on the case, which would look a lot nicer. The major gripe is that there is no UL or ETL listing, which is a big one for me. I have vowed to never use any electric devices that don’t have a UL or ETL listing, but I went ahead and bought this because there are no other products like this on the market and the reviews here on Amazon, as well as several online forums, are very positive, so fingers crossed. I know testing costs money, but it seems as if the company could balance that expense out with more sales from the people that won’t buy unlisted products. It does work very well at turning the fan on and off simultaneously with (and sometimes slightly before) the receiver, so good 12V triggering from the receiver and good sensitivity from the device. Hopefully, there will be no regrets about the lack of UL or ETL listing, because I really like this device despite the rather cheap-looking adhesive labels.

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.

Unlike another product I tried, this one just worked without a lot of fuss. It's great, and I highly recommend it for use with a product like a home CNC system where one wants to have the controller be able to turn a router on and off, while also powering a dust removal system. What's even more cool is that it has both normally on and normally off outlets.

5.0 de 5 estrellas Perfect for fan control home audio
Calificado en Canadá el 1 de abril de 2024
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.

5.0 de 5 estrellas Works well for Bang and Olufsen
Calificado en Canadá el 6 de marzo de 2021
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.

5.0 de 5 estrellas Just what I needed to manage shore and battery power in my motor home.

 Well priced, delivered quickly, solid construction. I’m very pleased with this switcher. I recently installed an inverter in my RV to enable me to run some 120v items in the RV when on the road or not plugged into shore power. When switching on the inverter, I had to open the dinette seat to get access to and unplug or turn off the RV converter/charger (they should not run together). With this switcher I have a 6 volt wall wort adapter that is plugged into a spare outlet on my inverter to trigger this switcher. When I turn on the inverter (via its wall mounted control), this switcher senses the inverter power coming on , via the adapter, and automatically turns off the converter/charger unit. I have the converter / charger plugged into the “normally on” outlet. When I switch the inverter back off, the voltage from the adapter drops and this switcher turns the converter/charger back on. Fantastic, and easy to do. Except for the triggering input, this device is plug and play and does both “normally off” and “normally on” circuits. I was going to built one myself but this Unit did the trick and for a reasonable price. This makes managing these two 120v devices a one button operation.
