Hello everyone,
Im in need of some help and ideas.
Here is my issue
I have an analog signal input go into PLC, and whenever my pump was shutting down, this analog signal always spikes for exact 8mA. stays there for various amount of time. the set up is very simple, analog signal coming out from one of the analog output on a controller, and go into one side of terminal, and other side terminal is go into PLC analog card. I also have only shield ground for one side.
Has anybody run into this issue before?
Really appreciate your helps.
