Potentiometer input to DC transmitters

Don Horne   

GetImage7Omega’s new DMD4008 series of transmitters accepts a resistance input from potentiometer, slidewire, linear position, displacement or rotational devices and provides an optically isolated DC voltage or current output linearly related to the potentiometer position. It’s a quick setup for hundreds of I/O ranges, features external switches and table for range selection, has removable plugs for fast installation with a functional output test button and selectable sink/source for current output. Applications include over, under, out-of-range position monitoring, remote control of position monitoring, remote control of positioning devices and simplifying control of potentiometer outputs.
