Great little relay

Great little relay
I got this to remotely control my two sub-woofers in my home theater. I had problems with them turning off automatically when the sound stops. I even had one sub-woofers internal amp fail because it was on 24/7. Now I can flip a switch on the equipment rack and they turn on or off.I did notice the inclosed instructions say the relay is NC or normaly closed. The instructions also state the relay closes when 12volts is applied. See photos of instructions.My setup works the way I wanted and expected it too. When there is no 12volts supplied too the relay the load is OFF. Apply 12volts and the load turns on.

Worked fine out of the box. Small / compact. Wish the screw terminals were bigger to support a standard lug. On this unit I had to use the smaller lugs (which I had on hand). Because i used this as an interface with my Honeywell Vista 20P, trigger 17 (Programmable Output) for my alarm siren / bell / accessories.... I needed a reply that did not have an optical sensor.... just a straight contact to the relay and low current consumption rating on the coil.

The Vista 20P has limited output for trigger 17 (limit to max 100ma).... so I also removed one leg of the small led on the board to not light up. You can add a led on the output of the relay contact if you really need a led to show you when the relay is activated. This saved about 5 ma which reduced my limit on trigger 17 output.

What is nice about this is the fact I did not have to spend another $100 bucks for a honeywell add-on power supply that only supported 1.5 Amps, and a honeywell relay board. By connecting the output of trigger 17 to this relay directly, then using a separate battery and power supply to support the Wiper/NO contact loads on the output side.... I am able to run up to 30 Amps if desired .... but really only using about 5 amps at this time for everything.

This relay board also has a nice large value capacitor across the coil, and I recall a diode as well... This helps with any spikes from the coil and/or reverse current when the relay disengages.... the spike can effect sensitive item (chips). I had no problems with this replay on my Vista 20P board. I made a plex-glass board for 2 of these relays which fits exactly into the slotted spaces in the Vista 20P box, and mounts perfectly.

Reviewed in the United States on April 24, 2024
Size: 40AVerified Purchase
I wanted some high-amperage lights on my electric scooter lighting circuit, but the standard lighting controller could not handle the current. So I wired the relay in so that the 12V would receive power when the standard lights turned on, which would trigger the relay and activate the main lights.

The relay is probably not 40 amps, but it works with the 10 amps I’m putting through it. It’s NC (normally closed) so when no power is applied, it’s closed.

I am a former electrical contractor used to installing substantially larger relays and contactors for controlling 120v loads. Visualizing this piece of equipment in comparison to previous equipment made me hesitant to use this relay to control a 120v water heater in my camper. I tested it before installing it, then tested on a 45 day road trip. It has operated flawlessly. I'm still amazed and would buy it again.

2.0 out of 5 stars Not quite as described - merely a SPST relay instead of a DPST relay
Reviewed in the United States on July 18, 2019
Size: 30AVerified Purchase
This device is NOT as specified. First and foremost, even though the pic and description would lead you to believe it can switch two circuits (ie; two inputs and two outputs, or a Double Pole, Single Throw relay), in reality the two inputs are shorted together and tied to a single relay contact - same with the two outputs. Therefore you can only switch one circuit (Single Pole, Single Throw relay). For power purposes, this means you can NOT use this to switch a two phase (ie; 240 VAC) circuit but instead can only use it to switch a single phase (120 VAC) circuit. This is a huge limitation, and other relays (such as model LY2NJ) are available at much lower prices with additional features.

Secondly, as other reviewers have stated, this relay can not handle 30 amps, and will self destruct if used to handle that much current. Additionally, the coil for the relay also draws more power than specified, although this flaw is not likely to impact most people as much as the first two limitations.

BOTTOM LINE: If you are simply looking for a basic relay to switch a low power circuit using a 12 vdc input in place of a simple 'On/Off' switch, this will do the job but there are less expensive and more reliable options readily available on Amazon. If you are seeking a relay based on the specs listed for this unit and/or need DPST operation, look elsewhere as this unit is NOT as listed. The only reason I increased the rating from one star to two is that this unit is easier to hook up than most others that fail to clearly identify which pins on a socket base are for the coil, contacts, etc... No such confusion exists on this unit as everything is clearly labeled. With that in mind, IF the relay was truly as described - "two inputs and two outputs" with 30 amp capacity - it would have gotten 5 stars.

I have this hooked to a float switch to turn off power to my aquarium water pump if water gets too high in my overflow tank. Make sure you don't have any plugs plugged into the wall before continuing to read the following tips which might be helpful... The red and black wires you see in the product picture hook to your 12 volt power adapter (purchased separately). If you have an old 12 volt power adapter that came with your Walkman or portal CD player...just use that : - ) The 12 volt power adapter you have has two wires...just cut one of them in half (I dont think it matters which one) and connect back together with your float switch wires. So now your float switch breaks 12 volt connection to this relay switch which in return breaks connection to the 120 volt wire(s) you have screwed into the 4 screw terminals you see in the product picture. The two left screw terminals are marked with K0 and the other two right screw terminals are marked with K1 (I only needed to use two screw terminals for my application). Finally, do the same thing you did above and just take the black wire coming from your 120 volt wire (whatever appliance, light, or equipment your trying to turn on/off with this relay switch) and cut in half, stick one side into 1st screw (K0) and the other side into the 3rd screw (K1). Wala! If float switch interrupts 12 volt power, the relay switch interrupts the 120 volt power. I bought a small plastic junction box to contain the wires and house this relay switch and cut the female end off of an old extension cord to connect my 120 volt aquarium pump..
