DMS-20PC-0/5 Series
0-5V and 0-10V Input 3½ Digit, LED
Display 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.
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.

TECHNICAL NOTES
1. Input Configuration: The DMS-20PC-0/5 has its input low terminal
(TB1 "LO") internally connected to the power supply ground terminal
(TB2 "–V"). This connection effectively places the meter's input in a
single-ended configuration. In some applications, single-ended inputs
can cause ground-loop induced errors (the meter's display becomes
unstable or bounces). This occurs because the LED drive currents
flow through both the –V terminal and the signal LO terminal.

If suspected ground-loop errors are encountered, and the input signal
LO terminal is externally connected to –V somewhere else in the
system, try removing the connection to TB1 "LO". Inputs which have
no ground-return connection to –V (commonly referred to as "floating
inputs") must have their most negative potential tied to TB1 "LO".
Please consult DATEL for more information.

OPERATING AND SETUP INSTRUCTIONS
As shipped, the DMS-20PC-0/5 is factory calibrated to read "000" for
a 0.0V input and "1999" for a 5.0V input. The following worst-case
procedure assumes the DMS-20PC-0/5 is completely mis-adjusted, i.e.,
both potentiometers and the DIP switches are randomly set.
Polycarbonate
Weight
0.6 ounces (17 grams)
1. Set R7 (full scale span/gain adjust) and R3 (zero/offset adjust) fully
clockwise, roughly 22 turns, and place SW1-SW8 to OFF (down
position).
~ The DMS-20PC-0/5 can also be used in most 0-10V applications. See the section
on 0-10V inputs for more information. See Note 3 on Table 1.
INPUT LO (TB1 "–LO") is internally connected to the power return (TB2 "–V").
Overvoltage specifications apply to the INPUT HI (TB1 "+HI") connection.
2. Select DIP switch setting #1 in Table 1.
3. Apply a precision 0.0V input and adjust R3 until the meter's display
reads "000".
4. Apply a precision 5.0V input and adjust R7 until the meter's display
reads "1999". Repeat steps 3 and 4 to make sure the adjustments
do not affect one another.

5. Select the appropriate decimal point by setting SW6, SW7 or SW8 to
ON (DP1, DP2 or DP3 respectively).
NOTE: The "000" to "1999" display readings referred to in the
instructions above are for illustrative purposes only. If other display
readings such as "000" to "1200" are desired, refer to the DIP-
Switch Settings Tables for SW1-SW4 settings. (SW5 is reserved for
future use, it has no affect on display operation.) The initial setting
of R3 and R7 fully clockwise is recommended in the adjustment
procedure for all the following examples.

used. Set SW6, SW7 and SW8 to OFF.
While the DMS-20PC-0/5 is optimized for operation with 0-5V inputs,
its versatile input stage can also accommodate most 0-10V applica-
tions. The meter's zero/offset potentiometer (R3) has enough adjust-
ment range to produce a "000" display reading with input signal levels
between –0.1V and +1.0V. Table 2. summarizes the available ranges
when the DMS-20PC-0/5 is used with 0-10V inputs.

The DMS-20PC-0/5 is optimized for handling 5V signal ranges that are
positioned between –0.1V and +6.0V. As such, input ranges can be anywhere
between –0.1V to +4.9V and +1.0V to +6.0V as long as their full range is
5 Volts. The meter's zero/offset potentiometer (R3) has enough adjustment
range to produce a "000" display reading for input signal levels between
–0.1V and +1.0V.
Please note the DMS-20PC digital panel meter from which the DMS-20PC-0/5
is derived has an accuracy specification of 2 counts (max.). Thus, it may not
always be possible to obtain the exact desired display readings.
