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 difﬁcult-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, simpliﬁes 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 ﬁrst loop-powered digital panel meters

Both gain (span) and offset (zero) adjustments are performed with on-board, precision,

... Humidity (non-condensing) 0 Case Material Weight The DMS-20PC-4/20, using any of the DIP-switch settings described above, can withstand overcurrents, including those resulting from accidental reverse-polarity connections ±40mA without sustaining any damage. Because DATEL's DMS-4/20 loop-powered meters employ active circuitry to convert the loop current into a voltage, the meters' effective series impedance varies in a manner that maintains the loop voltage drop constant over the full 4-to-20mA current range. Listed impedance speciﬁ ...

... This example illustrates the DMS-20PC-4/20P’s capability to display higher differential readings than those indicated in Table 3. This example also illustrates how the DMS-20PC-4/20P can be used to display the output levels of a 4-20mA loop transmitter with higher preci- sion (0.01mA versus 0.1mA) than described above. ...
