Loop-Powered, 1.8V Drop, 4-20mA Process Monitors with Full-Size LCD Displays

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 floating 2-wire design allows DMS-30LCDA-4/20 Series process monitors to be connected anywhere in the current loop.
