DMS-30LCDA-4/20 Simplifi ed Schematic Murata Power Solution’s new DMS-30LCDA-4/20 Series’ 1.8V nominal loop-drop is the lowest of any comparably priced, 4-20mA input, 3½-digit process monitors with full-size LCD displays. This super-low loop-drop guarantees a maximum burden of no more than 100 Ohms! And because it’s loop-powered, all operating power is derived directly from the loop current itself; no separate power source is required! Their fl oating 2-wire design allows DMS-30LCDA-4/20 Series process monitors to be connected anywhere in the current loop. All decimal point and range-change selections are made via an eight-position DIP switch which features vibration-resistant, gold-plated contacts—there are no cumbersome jumpers or solder gaps to contend with. Both gain (span) and offset (zero) adjustments are performed using 20-turn, non-interacting potentiometers. Four different models accommodate unipolar, bipolar, positive, and inverse display-reading applications. The DMS-30LCDA-4/20 Series’ DIP switch and adjustment potentiometers can accommodate literally hundreds of different input-current/output-reading combinations. DMS-30LCDA-4/20 Series’ subminiature package houses a large, 0.40”/10.2mm, high- contrast LCD display that can be read in virtually all lighting conditions—including full sunlight! The two connections to the external loop are made via a reliable screw-type terminal block. For environmentally demanding applications, an optional panel-mount bezel assembly, featuring screw fasteners and a rubber gasket, provides excellent resistance to dust and moisture. All these outstanding features combine to make the new DMS-30LCDA-4/20 Series ideal for all your 4-20mA process-monitoring instrumentation needs.
