Hello,
So i am looking to create a simple RF Transmitter and Receiver unit for a 4-20ma Current loop sensor.
I know bits and pieces, but the simpler the better! haha
I know i will need a RF transmittern and reciever
and ADC converter to change the Signal from 4-20ma to a 0.25 - 5vdc signal. and...
I want data from a 12v windspeed sensor that communicates with a 4-20mA signal. I chose a XY-IT0V breakout board to receive the signal. The XY-IT0V documentation (see link) describes two pots that set the bottom and top (span) output voltages to correspond with the 4-20mA input. I chose...
Why does this not work?
I can adjust the pot and the relay will energize. The 4-20mA will not energize the relay even if I set the pot very close to the energize point.
