The DC 24V 4-Channel Relay Module is a high-quality industrial-grade control board featuring four independent relays capable of switching loads up to 10A at AC 250V or DC 30V. It incorporates SMD optocoupler isolation for stable, low-current triggering and offers flexible high/low level trigger settings via jumper. Designed with fault tolerance to prevent unintended activation, this compact module (73x50x17mm) is ideal for PLC automation and industrial system control.

Work as advertised
No issues so far but they also have not seen a lot of use just yet. They work as they should and are decent enough quality. Thew real test is how well they stand up over time.These are being used to switch mains voltages using a 24VDC control signal in a CNC control.

Great product, but make sure you connect it correctly
Great product, but make sure you connect it correctly. DOES NOT HAVE POLARITY PROTECTION!I was in a hurry and didn't check polarity. Poof..Ruined whole board, even though it appears the relays are isolated .

DANGEROUS! This is not a 30A relay.
First of all this relay doesn't have a connector that can accommodate a 30A wire (10 gauge). But if you can manage to connect it to 120v and attempt to control a 1500w heater (12.5A) the relay will get hot enough to melt the encloser and then stick closed (on position). So the current is never broken to the heater, and the relay continues to heat up. This could cause a fire which could in turn destroy property or even worse, kill someone. These should be taken off the market. I tried 3 of the 4 I bought to control this heater. All 3 melted the box they were in and failed within 15 min. I have since bought a true 30A relay and it runs my heater just fine. I will use the fourth one in a low current, less than 10A project like turning on a light bulb or something. It should work for that. If you need a high amp relay PLEASE DONT BUY THIS ONE.

Poor quality control
Looking at the bottom, the soldier joints all look like cold joints. Several of them have significant pitting. Easy to fix, but I shouldn't have to do that.Additionally, if this is really capable of 30A 240VAC as the description states then they have massively undersized the conductors on the board.

Worked perfectly
Does what I wanted it to do. Construction and solder joints look solid, no complaints.
