+24V Isolated-power models
Low power consumption, 15mA from +5V
100Ω impedance, 2V loop drop
DIP-switch selectable range and decimal points
Hundreds of different input/readout combinations
Vibration-resistant package; Reliable screw-terminal
input connections
High-quality, 20-turn, gain/span and zero/offset adjust
potentiometers
panel meters offer an outstanding combination of electrical performance, display read-
ability, ease-of-use, and long-term reliability. Each of the 5 models features a large
(0.56"/14.2mm), red or green, LED display. Low-power or high-intensity red models are
optional. Power supplies can be a single +5V or an optional, wide-range +7.5-32V (24V
nominal). All DMS-30PC-4/20S meters are constructed using DATEL's super-reliable, ?eld-
proven, epoxy-encapsulated DMS-30PC digital voltmeters. The entire assembly utilizes
100% soldered connections. These are the most rugged, 4-20mA input, panel meters in the
world.
Gain (span) and offset (zero) adjustments are both performed with high-precision,
20-turn potentiometers. All decimal point and range-change settings are made on a gold-
plated, vibration-resistant, DIP switch; there are no cumbersome solder gaps or jumpers
to contend with. Connections to the current loop and the power source are both made on a
rugged, four-position, screw-type terminal block.
The DMS-30PC-4/20S's user-friendly design accommodates virtually hundreds
of different input-current/output-reading combinations. This eliminates the majority of

requirements for more costly, long-lead-time, factory "specials"– especially in applications
requiring several different-range meters. A bezel assembly, featuring secure screw fasten-
ers and an EPDM rubber gasket, is available for applications requiring moisture and/or dust
resistance.
