The project is at a very early stage of development. At the moment, a prototype is ready (100% hand made :)) and a test program based on my research on the stable operation of devices without a controller and gate. - Happy Standby Node :) | MyS Network Scanner (4 sec.)
You can express your opinion on the forum, support my project.
Characteristics of the device:
ATSHA204A (Crypto Authentication)
4 channels 16A
FTDI and ICSP header for programming
Automatic network search
When the load is switched on, the ssr relay starts, after 100 ms the electromagnetic relay is switched on and ssr is turned off. Such a scheme to ensure the operability of the relay electromagnetic relay, which greatly increases the service life.
The operating modes of the relay are implemented, thanks to the joint operation with the ACS712 current sensor. For example at a load of 100w only the ssd relay will turn on, the electromagnetic will not turn on ....
See the oscilloscope below in the photo.
Now we are working on a serial version of the PСB.
