DPM 342
LED Backlit 4-20mA Loop Powered Indicator
A compact loop powered indicator giving an accurate, zero corrected indication of 4-20mA loop current. Calibration is by two multi-turn
potentiometers which allow sensitive adjustment of the instrument. The DPM 342 features an integral snap-in bezel, making installation
easy. The module’s LED backlighting ensures a clear display, even under low light conditions. No soldering is required. Connection to the
current loop is via two screw terminals. The correct decimal point is selected via a jumper link.
