Potentiometer input-to-dc transmitters

Potentiometer input-to-dc transmitters

The 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. A quick setup for hundreds of I/O ranges, the device has external switches and a table for range selection, removable plugs for installation with a functional output test button, and selectable sink/source for current output. Applications include over, under, and out-of-range position monitoring; remote control of position monitoring and positioning devices; and simplified control of potentiometer outputs.
