Fairly new to PLC. I've created a system that can move an arm via Servo Motor and drive as well as operate some solenoids and power switches. Customer is now looking to be able to read voltages in case there is a fault, for troubleshooting.
I'm using Automation Directs 2000 series and I cant find an analog input that will read above 10V.
I have 24V and 12V. Is this a case where I need to read the current instead and can I then program some math in to convert it back to a voltage reading or is there some sort of step down device.
I thought the answer was a signal conditioner to read current and output voltage but i seem to be wrong.
