Potentiometer Input to DC Transmitters

February 19, 2014

Omega Engineering potentiometerOmega’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 that is linearly related to the potentiometer position. The DMD4008 is a quick setup for hundreds of I/O ranges. It features external switches and table for range selection and 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.
