Review on Electronics Salon SPST NO Module Control Voltage by Born Waheed

Trying to use this in a heating system to switch pumps. The side relay power supply (24VAC) blew and my 24V power supply (transformer) died. This is only the case after less than 24 hours of use. I would absolutely not recommend this relay. Look at the picture showing the burnt diodes for the input of one of the relays. This should never happen. Especially after less than 24 hours of use. Ultimately, this causes me to buy a new 24VAC transformer and worry about the potential fire hazard, which fortunately didn't materialize. Don't buy this! (may work best with 24VDC but not 24VAC).
