2008年2月21日 · I once used a chip that converts 0-5v, 0-10V e.t.c to 0-20mA or 4-20mA, its the XTR110KP. Basically at the input side to this chip i had a Potentiometer and the XTR110KP was configured to give 4-20mA output. Really handy device for calibrating and cheap to built. The datasheet shows how to configure it for the above.

Issue on 4-20mA signal,cannot determine where the fault is, as ...
2020年10月23日 · So I worried that the Analogue input board on that particular channel might be faulty. So I look for other sensors adjacent to it with the same 4 -20mA and then reconnect it to the channel that is in question. It seems like the channel is working fine that it gives a rpm reading with that temporary 4-20mA signal from the other sensors.
