with a large, easy-to-read, bright red, LED display. All operating power is derived
directly from the loop current itself—no external power supply is required! The large,
0.37"/9.4mm digits exhibit uniform intensity over the entire 4-20mA operating range.
Additionally, the total maximum loop voltage drop is only 5V! Users no longer have to settle
for diffi cult-to-read LCD displays in loop-powered applications.
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.
hundreds of different input-current/output-reading combinations. This versatility practically
eliminates the need to order more costly, long-lead-time, factory-customized "specials" in
applications in which several different-range meters are required. An optional bezel assem-
bly, featuring screw fasteners and a rubber seal, simplifi es panel mounting and provides
excellent resistance to environmental dust and moisture. All these outstanding features
combine to make the DMS-20PC-4/20 Series the perfect meters for prototype and OEM
4-20mA current-loop instrumentation.
The DMS-20PC-4/20 Series are the world's fi rst loop-powered digital panel meters
Both gain (span) and offset (zero) adjustments are performed with on-board, precision,
