Python code for controlling RLY02 (usb module with 2 relay outputs at 16A )

The relays are identified by 1 and 2 and the allowed actions are on, off and click. You can interact with them with things like:

python rly02.py -r 1 -a on

python rly02.py -r 1 -a off

python rly02.py -r 1 -a click

python rly02.py -s

NOTE: ensure that you have the correct permissions in /dev/ttyACM0 for your user.

There is a separate Python program capable of controlling the RLY08 with eight relays. It works just like the RLY02 program, but accepts relay numbers (-r) up to 8. This program is backwards compatible with the RLY02 board.

python rly08.py -r 7 -a on

python rly08.py -r 7 -a off
