Thank you for sharing such an awesome project! I got everything to make this and it doesn't fit the listed SRA-05VDC-CL relays. It looks like it fits the slightly bigger (SRD) version. Also the 2p connector is listed to use a KF350-2P, but actually needs a 5mm KF301-2P.
Tengo un problema y es que no se activan los relay cuando lo programo en openPLC, pero en Arduino si le pongo alguna de las entradas en modo salída funciona perfectamente
I made this bored. But input d4 isn't working. I think this is because it has a internal pull-up resistor and the board has a external pull-down resistor between the pc817 and the d4 input. How do i disable the internal resistor?
Yeah I just confirmed on your board. GPIO2 pin D4 that's connected to the onboard LED with the pull-up resistor is a sinking input unlike the others. You have the pc817 output pins of D4 reversed for sourcing.
He used OpenPLC for programming the ESP module, using OpenPLC you can write Ladder language and other languages program but in his video he used Ladder language to program the module. Method from programing ESP module using OpenPLC is that you just write a program in Ladder Language and for the input and output variables you map the variable to pin numbers of module (Pin mapping is mentioned on OpenPLC documentation website) and then you just burn the code on module using OpenPLC burner, it automatically converts ladder program into C and burns it on ESP module.
it isolates the 3v3 esp from higher control voltages and is absolutely necessary.. an alternative is a voltage divider, but this does not protect the controller from transient voltage spikes.. optical isolation is the gold standard here and this is the appropriate choice
Please write your email, I need to develop a PCB project for esp8266, 8 relays, 8 4-20ma inputs, 16 inputs via a shift register for a button and 16 5v outputs via a shift register, I would also like a built-in OLED display connected via 4 pins, could you design such a PCB for me?
Why the PCB doesn't seem to have any of the mentioned optocouplers, but it DOES have diodes near each relay?
Any alternative for relay or any ic?

That's a cool circuit.
Can you show me the programming procedure ?

This plc can be used to run 4 to 6 sg 90 servo motor to make a project
it has relay output so it can not run servo for that new version is coming soon
Sir three phase voltage measure microcontroller any ideas
soon bro
I am waiting sir
hi, i wonder how do you determine the resistor value needed for each connection?
use Ohm's law
is it holds good for 24 Vdc supply also
Can you provide the plc program link
Good work guys.
What is is it use for
can be programed easily with ladder logic and used for small scale industrial projects
@@KiyanisLab have you applied to something?, how did it do?, thanks fro sharing
Please, I have stabilizer transformer but I need the circuit to control it from 100 to 280v to 220v a/c current
SOON
@@KiyanisLab thanks let it be very soon
Good job! I'll take more.
Great work 😍
what's a good design, but i still confuse how to program the ESP822 module, i think that the success key for this project.. share please..

I need this Circuit how I can buy this

Salam sukses selalu.
The optocoupler seems to be pretty useless.
it isolates the 3v3 esp from higher control voltages and is absolutely necessary.. an alternative is a voltage divider, but this does not protect the controller from transient voltage spikes.. optical isolation is the gold standard here and this is the appropriate choice
Very nice
Good
Thanks sir
Could I use this plc to control an ice cream
Machime
good PLC has isolated Inputs, Outputs, AD, DA - my idea is much better
Good work, but video is bad man. Why did you show every step of connection?! Took like forever... ((
Bro do you even know what isolation is? 😂😂
