Looking for a simple "controller" that fits in a standard 3.77 x 3.77 (96 x 96) cut out.
We have many different controllers here which will do the job, but they are expensive, total overkill and usually have small two line displays.
What I am looking for is a unit which has only one display line, gives me a 0 - 100% display, has an "UP" arrow and a "DOWN" arrow.
At 0% it outputs 4 Ma and at 100% it outputs 20 Ma
Thats it no need for inputs, pid etc. etc.
It's just basically a digital display "4 -20 ma potentiometer" with up/down rather than rotary movement.
Does such a unit exist, anybody ?
