Can you safely use these relays to switch low power 110v loads with a 5v controller?

Yes - If properly wired the opto-couplers protect the controller and data lines from the relay circuit.

You will need to use a relay in order to do something like that. The switch alone cannot handle that much current, it is meant for very low voltage situations, or use with a relay switch.

The output relay contacts are rated for a maximum of 10 amps at 30 volts DC - so, yes, this will work for switching LED strip lights. The overall current drawn by the 5 meter length depends on how many LEDs there are. As long as the total current is less than 10 amps, no problem. (And, the current to drive each LED is typically low, so it is probable that the total current is well under 10 amps.)

you could use this for that, you would just need to add a large relay or solenoid to handle your current, so that your load isn't wired through this...

This relay is activated by a 110 volt signal on its own cord. I have been using them to relay both 220VAC on a 30amp breaker and 110 on a 20 amp breaker. They work quite well. Any system that will switch the 110VAC on and off can operate this unit. Hope this answers your question. Alan PS if you have a system that only has dry contacts you would need another relay for the 110VAC to make this work and at that point, you would be running a relay with a relay and that doesn't make a lot of sense.

I would be cautious, I am no expert but these converters manage smaller devices, lamps etc very well. BUt they did not handle larger appliances, they would blow the fuse fast.

You have to supply 12V for Vcc and ground to the relays. The in1-4 can be triggered directly from Arduino outputs as long as your 5V and 12V supplies share a common ground.

I would day it is best to use a relay, unless youuse aheavy dutyswitch. Most switches are not designed to handle a load running through them, even though these lights only use about 5 amps to run both.

Yea, I would assume. I used it to protect a PID controller. Standard outlets are 15a at 110/120v and you pick the fuse to go in it. 1a to 15a fuses... work fine for me

This is a relay. The relay is powered by 120VAC, but the contacts of the switch are completely isolated from that 120 VAC, so that you may run almost anything off it, including low voltage devices. I use several of these to control low voltage devices and it works fine.

I have been using this to run the AC power from the wall, 110VAC. The Arduino pins have plenty of juice to toggle to relay. I have run mine for extended periods and have not had it fail yet. Only bought one. I plan on buying more soon.Application: Power relay from Sanguinololu 1.3a installed on MendelMax. Powering 110VAC-12V 20A power supply.

yes, you to connect at 110 volt electric current.and this is a remote control operator

I would be concerned about burning this up with so many amps pushing through what looks like a pretty small component. However it sounds like the idea here is for this to be the wireless bridge to a separate relay so depending on the specifics of that other relay as others have described here and it can handle the power it should work. In addition to that, in an ideal setting, your control logic software should have a routine for confirming startup and retry after failed start.

As far as I know there really are no options, the relay switches one leg of the 220v power with with a 2-wire 24v thermostat. If you want to switch 110v instead you need to buy the suffix -120 version. Hope that helps

i used it to connect an array of solar panels. don't know why you would want a relay, but you could connect a inline fuse if you wanted to.

The relay enables are DIGITAL, so 5V signals. Can use resistors in line to divide the voltage for 12V activation if desired. The RELAY outputs can carry 10 amps each up to 28VDC or 250VAC.

As MSGroves pointed out, each switch is meant to control power flow to each block of 9 connections. It would seem that in the unit you received the switches are not working and power is stuck in the "on" position. As S. Howe pointed out, the low voltage, 12V, is too low to be a safety concern.If you purchased it recently and you are still within the allowed replacement period, you may want to have it replaced for one that functions as it is supposed to but, not for any safety concerns.
