TWTADE/JQX-12F-2Z DC 24V Coil Voltage 30A DPDT 2NO+2NC General Purpose High Power Relay 8 Pin

Used to connect an inverter to a load while preventing any back feed..I was unsure if this relay had a 100% duty cycle as it would be energized for hours at a time. Happy to find it would run for hours at a time with no overheating. Works well for me and would buy again!!

Bought some 40A solid state relays from amazon thinking it would be more reliable and forward thinking. Wired it up, they locked on without any input voltage (like 20v shy of full power). This is a horrible way to fail (fail off maybe?). Should have trusted the reviews.So decided to just go mechanical relay. Oh look, it JUST works because you can't mess up decades old mechanical design. The description is accurate how to wire it up, but here's an image to clarify. Pins are typical 1/4" male faston so it's easy to add some female connectors to your wires.

I used this relay in conjunction with a car security system. I am able to both disable my starter and ground my coil at the same time. Relay is usually on and does not run hot at all. Easy to wire and hide because of its small size.

I looked at several Relays and even relay mounts, until I ran across this one.I like the built in mounting legs on the side shell. Makes it adaptable for projects.Just install a pop rivet or small bolts. The tabs are typical spade ends making it easy to install, remove connectors. The +12 v coil inputs are offset 90 deg's making it easy to determine them from load tabs.

It's a relay.I have the AC turning off a switching power supply to a battery with this relay with the AC coil, when AC is dropped, so the battery doesn't feed back into the power supply. A diode would work, but there is less power loss between the power supply and the battery, which makes adjusting the power supply easier, to charge the 12 volt 36 amp battery. This is part of a uninterruptible power source for may server.

I have not used it as a controller as yet, but it appears to have the electrical capabilities I am looking for.

Bought this relay to control a 1500W heater connected to a G4 remote switch (controlled with text messages...very cool). The relays in that remote switch were 10A, and I was concerned I'd trip the relays if I put 1500W through them at 110V, so I bought this 30A relay to activate the heater circuit. Works like a charm. As others have noted, the clear casing allows you to easily determine the normally 'on' and normally 'off' switch contacts (1 each), as well as the input and output contacts. It doesn't come with instructions, but frankly, if you're buying this device, you must already have a working knowledge of circuits so the absence of instructions isn't really an issue. Would buy another if I needed to.

Made up a bypass for my CNC router for when planing the spoil board. Ended up blowing fuse in controller due to router motor pulling to much amperage. This prevents that.
