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
