The relays refused to work (for lack of voltage) util i switched the bridge from Low to High.On "Low" The output voltage for 5V. DC is 5volts which is insufficient to get the relay to actuate.Setting is on "High", the voltage is now 6.3volts and now both relay can work at the same time.Requirement:If you receive your board with the bridge set on low, the High-Low 3 pin bridge need to be set on High

It’s pretty pathetic that there is absolutely no documentation explaining you have to provide a 120-240VAC input which will then power the “internal” circuitry and provide you with a 5V and GND output you use to switch the relays.That being said, it works great and I have not experienced the issues that others have mentioned about lack of power from the 5V output while closing both relays.

Purchased this to fix a shorted out relay on a raynor control hoist main board.Turns out the middle pair of AC contacts are wired to a 5v dc transformer.Great design. I was able to fix a $1500 shop door lift with a $15 part.Great work. Great design. Great value. Highly reliable so far.

I used this with a thermal switch to turn on my wood stove blower. With the on board 5 volt supply it allows you to safely switch 120 volts. It was just what I needed. It worked perfectly.

I've bought five of these relay blocks so far, and the two I received last Friday have less capable PSU.Admittedly, I am using the modules with a higher power demanding controllers based on ESP8266, so during boot WiFi modules consumes too much of the current for modules to handle. However, a 1000uF capacitor across the 5V/GND pins solved the issue, and they boot fine and work reliably after that.However, the last two modules fail to provide enough power for both relays to switch by ESP8266 at the same time and voltage drops to ~2.3V causing the controller to restart. One relay at a time works, two - cause voltage drop and restart.Also, one of the earlier modules I purchased has a "sticky" relay. When the switching voltage is applied nothing happens until you tap on that relay or shake the whole thing, at which point it switches.So I was forced to take the PSU from that malfunctioning unit and replace one on the newer units. It is working as expected now which tells me that the new PSU's are simply less powerful than ones before them.I would give the product 5 stars if they were providing ~750mA for the controller. Otherwise, they are only usable with programmable controllers that have no wireless.
