Clarification about Controllable Four Outlet Power Relay Mod

by TimeTraveller2017 on Thu Aug 17, 2017 10:10 pm

Hello,

I'm working on an IoT Home Automation project. I came across the introductory video for this product:

Controllable Four Outlet Power Relay Module version 2 - (Power Switch Tail Alternative)
PRODUCT ID: 2935

In the video Lady Ada mentions that we can control the 3 relays via an Arduino microcontroller. But how can one signal wire going in from the Arduino identify and control each of the 3 relays independently?

Or is it that when a HIGH signal is sent from Adruino, all 3 relays will be triggered?

Can you please confirm?

Thanks,
TT

Features:

A single input signal to switch four outlets: 1 always on + 1 normally on + 2 normally off.
Universal control voltage 3-60VDC or 12-120VAC, or connect directly to a 12V, 48VDC, or even 120VAC circuit.
Optical isolation, relay, hysteresis and de-bounce protection for added safety.
A large MOV used to clamp surges for clean 90-140 AVC power.
Durable SPDT control relay rated at 30/40A. More than 400k operations at 12A or 2million+ at 5A.
A 12A thermal safety circuit breaker switch prevents overloads.
Standard 24" C13 detachable cord included.
Mounting tabs
This power relay is professionally built and tested.

I'm interested in this product for a device I'm building. In the code that I'll need for the controller, how would I indicate which power outlet is which? Do they have set output names?

Sorry, I'm super new to all this. I'd really like to learn how to use the device because it seems super useful, but I'm not sure where to start.

single input signal to switch four outlets: 1 always on + 1 normally on + 2 normally off. You can only toggle all the Three controlled outlets not individual outlets.

Thanks for the quick reply. Sorry, I guess I'm having trouble understanding why there would be two different types of outlets (1 normally on + 2 normally off) if you can't at least control the two types differently.

For example, if one is normally on and the others are normally off, you can only switch them to the opposite setting simultaneously? (The 1 normally on to off and the 2 normally off to on?)

yes the two types will go 'opposite' at the same time. e.g. you could connect a heater to one and a fan to the other and when you switch, the fan will turn on and the heater will turn off at the same time

I'm using a Raspberry Pi Zero to control the relay and can't get the relay to change states (off to on for normally off)
the RPi provides momentary (<3 seconds) of 2.2 vdc control voltage but the relay does not respond.

Please advise whether the controllable relay will respond to 2.2 vdc
Also need to understand if the relay is momentary contact (and requires constant control voltage to remain in the changed state, or if it is a toggle and only requires control voltage to change states, then remains in the changed state until it receives another control voltage input.
thx

you definitely have to maintain the voltage at all times to keep it open or closed, but you need 3V to trigger it

I ordered the Controllable Four Outlet Power Relay Module version 2 from you guys and I have a question about the trigger input voltage/current requirement. I am wanting to turn this unit on to power an audio amplifier in my home theater room. My AVR has a 12 vdc @ 150 ma max. trigger output that I will use when this AVR is powered on. I see that 12 vdc will work but was wanting to know if the current draw was less than 150 ma. I am assuming so since the input to your unit is opto-isolated controlled.

yes it will be less than 120mA for sure, its isolated and requires only logic level

Hello,
I recently purchased a controllable four outlet power relay module and tested it out with my R Pi 3. The relay does not work at all. I tested the GPIO pins from my Rpi and it is outputting 3.3v which should be triggering the relay, but nothing happens. I then tried it with a 5v input and still nothing. The relay module does power on, and the always on outlet works. Any help would be appreciated.

do you hear any clicking when you apply a voltage? does the switch Active LED light up?

I don’t hear any clicking and the light does not come on.

ok last thing to check, the green terminal block i think is removable, maybe check its well seated?

Tried it for a third time making sure the terminal was in as far as it would go. Still nothing.
