Hi,
As maybe some of you have read I have a remote controlled Observatory and in order to know if a device is working or not I did setup some switches in order to measure if there is current or not which means the device is working or not.
Here an image of my setup. Quite rought but it works nice. The coils were handwound and inside the coil is a reed relay. If current flows = reed relay closed I send a 5V signal to an AD reading port of my cards and signalize this on my GUI with green light. No current = red light
Now my question is : ¿ Is there a way to use whatever electronic components and substitute my archaic coils and relays ?
The maximum amperage flowing here is at around 4amp.
Thanks for any tips
regards Rainer
PS I hope this post is here in the correct forum ¿? is not moderators please move it
