DPST 1NO 1NC 8Amp Power Relay Module, AC/DC 12V Control Voltage

Did survive only a week

Reliable relay for a custom circuit

I installed this on my car to enable/disable the parking lights relay which was faulty, with this module I forced my car to behave as it should, then I did not have to submit my car to an expensive and difficult repair. The chassis, led light and embedded cables are quite convenient and make the installation a breeze.

I ran into the issue where I had to flow-pace a sampler via a flow meter's pulse output. The flow meter had a powered pulse output, and the sampler had a powered pulse input. The two loop powers negated each other, so I had to find a module to de-power the pulse loop, and still provide a dry normally-open contact. This product worked perfectly for very a very reasonable price. This will work for samplers, wireless telemetry systems, SCADA, and anything else needing a dry contact closure. Only the powered loop pulse output is needed. I did not need any additional DC power to power this module. Go With The Flow!

I'm totally blind! I got this being I needed a relay to be able to connect the 12V output on my driveway monitor to an electronic door sensor that had a switched magnet trigger. The driveway monitor has about an 12V about 150/350MA output. Being this relay required very little power to trigger I figured it would work. So I ttook a chance on it and got it. Being totally blind! I had to use a Talking multi meter to determine what wire whir the closed default connection and open connection. After that, Had to have someone tell me what color the other two wires whir. New one would be hot and the other ground; Just not what was what. If you have the 4 wires on the left and the two on the right with the screw mounts down! The HOT wire is near the top on the right side and is Blue in color. At least that was what I was told. The bottom one on the right is Green and I guessed that would be ground being normally Black or Green is ground. Then again using the talking multi meter found out what was hot and ground coming off the plug for the driveway monitor. Hooked it up and triggered the driveway monitor and heard a click from the relay and the LED on the front of it lit up acording to my light detector. Then when the driveway monitor reset! Hear another click when power was cut. Then clipped off the magnetic switch on the wireless door sensor and connected it up to the lower left 2 wires on the relay for an open connection. Triggered the wireless driveway monitor and the wireless door sensor when using talkback on my cell phone went from Open to Closed status and back to open when the driveway monitor reset. Lastly went into the Alexa App and created the routine that said wen the door sensor named(Driveway Monitor sensor) showed CLOSED then announce through all Echos in the house that "there is a vehicle in the driveway". Then tripped the driveway monitor sensor again and all the Echos announced "there is a vehicle in the driveway". The driveway monitor itself works off of magnetics and detects iorn in the vehicle and not motion. So me this works for what I got it for and I did the wiring myself. Improvement for this is the ground or hot wires could have had a different design. Like one smooth and the other a ruff coding. then a person like myself would have been able to tell by touch what was what.
