DMR20-4/20S-G-C

Loop-Powered, 4-20mA Input, Green LED-Display, Unipolar Reading Process Monitors
DMR20-4/20S-G-C
Series Headline Loop Powered, LED-Display Process Monitors
Series Description Murata’s new DMR20-4/20 loop-powered digital process monitors feature a large, easy-to-read, bright LED display. All operating power is derived directly from the current loop itself—no external power source is required! The large, 0.30 [7.6 mm] digits exhibit uniform intensity over the entire 4-20 mA operating range. Unlike other loop-powered LED displays, the total maximum loop voltage drop for the red LED model is 2.5V! Users no longer have to settle for difficult-to-read LCD displays in loop-powered applications. Both gain (span) and offset (zero) adjustments are performed with on-board, precision, 20-turn potentiometers. All decimal-point and range-change selections are made on a six-position DIP switch featuring vibration-resistant, gold-plated contacts. Unlike competitive meters, there are no jumpers or solder gaps to open or close. Connections to the current loop are made via a reliable, two-position, screw-type terminal block. The DMR20-4/20’s DIP-switch and potentiometers accommodate hundreds of different input-current/output-reading combinations. This versatility eliminates the need to order more costly, long-lead-time customs meters in applications in which several different-range meters are required. The round plastic housing fits standard 1.20” [30.5mm] panel cutouts. An EPDM rubber gasket and hex nut simplify installation and provide IP67/NEMA 6 protection to environmental dirt and moisture.
