Process Control Monitors
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. An accessory 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.
