DATEL's DMS-20PC-DCM Series of self-powered, positive-reading, dc voltage monitors are great replacements for older, hard-to-read, analog panel meters. Simply connect a positive dc voltage across the rear terminals and the meters are fully operational — no additional components or power supplies are required! The large, 0.37"/9.4mm, LED displays can be easily read from 15 feet away. Four versions are available: +4.50-19.99Vdc (0.01V resolution), +8.0-50.0Vdc (0.1V resolution), +30.0-199.9Vdc (0.1V resolution) and +30-264Vdc (1V resolution). Built-in reverse polarity protection assures simple, trouble-free installation. All DMS-20PC-DCM's employ a high-resolution, 3½ digit A/D converter and precision metal-film resistors to achieve outstanding performance over an operating temperature range of –25 to +60°C. A rugged, epoxyencapsulated, polycarbonate case provides excellent protection against moisture, shock and vibration. The DMS-20PC-DCM's are designed to fit the same panel cutout as DATEL's popular DMS-20PC-X-LM ac-line voltage monitors Typical panel mount installation and suggested wiring (user supplied). 2.5 readings/second ±0.01V ±0.1V ±1V ±0.01V (typ.), ±0.03V (max.) ±0.1V(typ.), ±0.2V (max.) ±1V(typ.), ±2V (max.) 1.38" x 0.88" x 1.00" 3 & 3½ digit, LED, 0.37"/9.4mm 1 ounce (28 grams) Polycarbonate Environmental Operating Temperature –25 to +60°C Storage Temperature –40 to +75°C Humidity (Non-condensing) 0 to 95% Ordering Information DMS-20PC-0-DCM-C DMS-20PC-0-DCM-B-C DMS-20PC-0-DCM-G-C DMS-20PC-1-DCM-C DMS-20PC-1-DCM-B-C DMS-20PC-1-DCM-G-C DMS-20PC-2-DCM-C DMS-20PC-8-DCM-C DMS-20-CP DMS-BZL3-C DMS-BZL4-C +4.50 to +19.99V dc red LED voltage monitor +4.50 to +19.99V blue LED dc voltage monitor +4.50 to +19.99V green LED dc voltage monitor +8.0 to +50.0V red LED dc voltage monitor +8.0 to +50.0V blue LED dc voltage monitor +8.0 to +50.0V green LED dc voltage monitor +30 to +264V dc voltage monitor +30.0 to +199.9V dc voltage monitor Panel cutout punch Panel mount bezel assembly Panel mount bezel with sealing gasket Brass screws (6-32 thread) and a panel-mount retaining clip are supplied with each meter ~ Operation and accuracy at inputs above or below these ranges are not specified.
