Back-Lit LED Panel Meters Take Little Room

    In the 10 Series of snap-in, subminiature dc voltmeters and a 4-20 mA loop-powered meter, designers can find the right meter for applications in which space is tight and light is low. Digit heights are 0.22" on the DPM 1, 0.32" on the DPM 2 and 0.43"

    In the 10 Series of snap-in, subminiature dc voltmeters and a 4-20 mA loop-powered meter, designers can find the right meter for applications in which space is tight and light is low. Digit heights are 0.22" on the DPM 1, 0.32" on the DPM 2 and 0.43" on the DPM 3 and the 4-20 mA loop-powered PDM 342.Each voltmeter in the range operates from a 9 vdc supply and features auto polarity, auto zero, 150-µA current draw, and ±200-mV full scale reading. The DPM 342 has a low voltage drop of 5.6V, calibration pots for offset and span, screw-terminal connections, and loop-powered LED backlighting.
