DMR30 Series DC Panel Meters

The DMR30 panel meter series is developed by Murata Power Solutions for industrial applications. Comprised of several models, the DMR30 series offers the ability to measure direct current (DC), DC voltage, temperature, various process voltages, or current loops commonly used in industrial processes. All meters are powered through a 9 V_DC to 32 V_DC external source and configured via a touch-panel user interface. They are designed to fit in a 2” round mounting hole.

The DMR30-DCV1 model is a voltmeter that provides DC voltage measurement ranges of 200 mV, 2 V, and 20 V and has 4.5 digits of resolution. The DMR30-DCA1 is an ammeter that provides DC measurement ranges of 1 A to 1200 A when used with industry-standard external shunt resistors (50 mV and 100 mV output types) and up to 3.5 digits of resolution. The DMR30-PM1 process meter performs precision process signal measurements supporting 0 V to 5 V and 0 V to 10 V voltage and 0 mA to 20 mA and 4 mA to 20 mA current signals. It can be programmed to display voltage or current units and mapped to user-defined scales with up to 4.5 digits of resolution. Finally, the DMR30-TC1 temperature meter accepts J, K, T, and E type external thermocouple inputs and can display in Fahrenheit, Celsius, or Kelvin with up to 0.1 degrees of measurement resolution.
