Hey guys !
So I am new to this forum but I have falling inlove with the Arduino concept and deiced to do my college project with it.
I am basically trying to make a clone of an APC PDU,
Right now I am struggling on two things.
1) Finding a separate "relay switching" chip to control 8 different relays, the catch is, these are 16 amp relays and not the relays you can conveniently connect to the Arduino, the relays I have found need 24 volts to activate the coil. I have found this chip.
Will this chip do what I need ?
2)I need to have a current sensor on each plug (there are 8 of them). Now I have seen that a lot of people use the ACS712 chip but to my knowledege these chip will not be able to handle a 220v 16 amp load. So I then came across the circuits that use a current transformer. After doing some brief reading I decied to buy a current transformer yesterday when I was at the electrical shop and do some testing on it.
This is the one I bought
Now I dont know how the ratings for these components work but it look like it can read current between 1 - 60 Amps which is more than efficient.
Can some recommend how I can hook this component up to my Arduino.
Also would it be possible to get a chip that can have 8 inputs and then the Arduino can send a signal to that chip and tell what which data it wants to receive from the chip ?
Note I am using the Arudino Uno with a Ethernet Shield.
