5.0 out of 5 stars Two Four Channel Relay Modules

Just received these two 4 Channel Relay Modules and all worked as expected. The relays when on will draw @71 mA each so just keep that in mind. Read some complaints that the relays are a bit noisy (clicking on and off) as you turn it on and off, Yes you can hear it but I prefer to have positive confirmation the relay did cycle. At about 6 dollars per module or $1.50 per channel is a good price point. I would buy more in the future at this price point. All relays on both modules worked as expected with no problems seen after initial testing. Each module was packed in it's only antistatic bag and was nicely packed in a small card board board just big enough to protect both boards very well. Came on time. Very Happy.

Man, these little relays can handle some abuse! Switching them with 5V (low triggers them) I find they can handle about 40 cycles/second, which is more than I expected. Response time is very short and they have a very satisfying activation sound (though rather loud).

I will be putting these boards through their paces, so hopefully they hold up. A couple of them may see triggering rates in the 10Hz region from time to time, but nothing more extreme than that. They should withstand a few years of that, in any event, before a relay fails.

5.0 out of 5 stars Great little relay boards!

These relays work great for my application. I needed to provide a switch closure to one device, a 5V DC signal to another, and control 110V AC on/off to others with an Arduino Leonardo. All channels on both boards work perfectly. The only quirk is that, because of the opto-isolator, they require a "High" signal in the NO/NC position. A "Low" signal activates the relay.

The one unit in this 2-pack that works is great. On the other unit, relays #1 & #3 do not trigger (their LEDs light up, but no relay action). #2 and #4 work as they should.
