DATEL's DMS-20PC-0/5 Series are the world's smallest, full-featured, 0-5V input
process control monitors. Their large, easy-to-read, 0.37"/9.4mm LED displays are
available in a choice of 4 LED color/intensity options: standard red, standard green,
super-bright red, and low-power red. Two power supply input ranges are also available:
the industry-standard +5V and a wide-range +5V to +40V (which typically draws 9mA at
+24V).
Gain (span) and offset (zero) adjustments are performed with on-board, precision,
20-turn potentiometers. All decimal-point and range-change selections are made on an
8-position, vibration-resistant, gold-plated DIP switch. Unlike competitive meters, there
are no jumpers or solder gaps to open or close, and to further enhance reliability, the
entire assembly utilizes 100% soldered connections. Both power-supply and input-signal
connections are made via reliable screw-type terminal blocks.
The DMS-20PC-0/5's DIP switch and potentiometers accommodate hundreds of input-
voltage/output-reading combinations. This practically eliminates the need for more costly,
long-lead-time, factory "specials" in applications which use several different-range meters.
A supplied bezel assembly––featuring metal fasteners and a rubber gasket––simplifies
panel mounting and also provides excellent resistance to environmental dust and moisture.
All these outstanding features combine to make the DMS-20PC-0/5 the perfect meter for
prototype and OEM, 0-5V input, process control monitoring.
