(55mm x 23mm x 26mm)
The DMS-40PC-4/20S Series' superior design makes them ideal for use
in demanding 4-20mA process monitoring applications requiring a full 4½
digits (0-19999) of display resolution. Their full-size, 0.52" (13.2mm) high,
LED displays can be read in virtually any lighting condition and are available
in green, high-intensity red, or low-power red.
Two operating power supply ranges are available: a wide-input +7.5 to
32V model for use with popular +12Vdc and +24Vdc industrial supplies, and
+4.75 to 5.25V models for use with +5V logic supplies. The reverse-polarity
protected +7.5-32V red LED model consumes only 30mA from a +24V sup-
ply, but still provides excellent display brightness.
The DMS-40PC-4/20's input, span, and offset circuits all employ super-
stable, ±0.5% thin-film chip resistors. Long-term stability and accuracy are
assured by driving these tight-tolerance resistors with an ultra-stable, ±0.2%
bandgap voltage reference. And, unlike many competing designs, the two
precision 20-turn span and zero adjust potentiometers do not interact with
one another.
All range-change and decimal point selections are made by configuring
two gold-plated, vibration-resistant, six-position DIP switches. To further en-
hance reliability, both power supply and current loop connections are made
via reliable screw-type terminal blocks. All these outstanding features make
the DMS-40PC-4/20S Series meters the most rugged 4½ digit LED display
process monitors available.
