DMD4380 Series DC-DC Isolated Transmitter
Range Selection
See the tables to select I/O ranges for your application. It is generally
easier to select ranges before installation. The module label lists
common ranges.
For ranges that fall between the listed ranges, use the next highest
setting and trim the output signal with the zero and span potenti-
ometers.
Switches A and B: Input range
Switch C:
Input offset
Switch D:
Output range
Switch E:
"V" for voltage output or "I" for current output
Note that when using a current shunt input, it measures a mV drop
across a fixed resistance, typically 50 mV, 75 mV or 100 mV. The cor-
rect input setting would be the appropriate mV range for the shunt.
Electrical Connections
WARNING! All wiring must be performed by a qualified electrician or
instrumentation engineer. Avoid shock hazards! Turn signal input,
output, and power off before connecting or disconnecting wiring,
removing, or installing module.
See diagram for wiring examples. Polarity must be observed for input
and output wiring connections. If the input and/or output do not func-
tion, check switch settings and wiring polarity.

Using the Loop Power Supplies with Current Signals
Determine if your device (PLC, display, transmitter etc.) provides
power to the current loop or if the loop must be powered by the
DMD4380. Typical voltage may be 9-24 VDC at your device's termi-
nals if it provides power to the loop.
If your device does not power the current loop, the module can
provide power using the appropriate terminals as indicated on the
wiring diagram.
Module Power
Check white model/serial number label for module operating voltage
to make sure it matches available power.
When using DC power, either polarity is acceptable, but for consis-
tency with similar products, positive (+) can be wired to terminal 13
and negative (–) can be wired to terminal 16.
Mounting to a DIN Rail
The housing is IP40 rated and requires vertical installation on a
35 mm DIN rail in a protective panel or enclosure away from heat
sources. Do not block air flow. Allow 1" (25 mm) above and below
housing vents for air circulation.
1. Tilt front of module downward and position against DIN rail.
2. Clip lower mount to bottom edge of DIN rail.
3. Push front of module upward until upper mount snaps into place.
Removal
1. Push up on the bottom back of the module.

the Zero potentiometer for the exact minimum output desired.
The Zero control should only be adjusted when the input signal
is at its minimum. This will produce the corresponding minimum
output signal. For example: 4 mA for a 4-20 mA output or –10 V
for a ±10V output.
4. Set the input at maximum and adjust the Span pot for the
exact maximum output desired. The Span control should only
be adjusted when the input signal is at its maximum. This will
produce the corresponding maximum output signal. Example: for
4-20 mA output, the Span control will provide adjustment for the
20 mA or high end of the signal.
5. Repeat adjustments for maximum accuracy.
Output Test Function
When the Test button is pressed it will drive the output with a known
good signal that can be used as a diagnostic aid during initial start-up
or troubleshooting. When released, the output will return to normal.
The Test Cal. potentiometer is factory set to approximately 50%
output. It can be adjusted to set the test output from 0 to 100% of
the output span. Press and hold the Test button and adjust the Test
Cal. potentiometer for the desired output level.
Operation
The DMD4380 accepts a DC voltage or current input and provides an
optically isolated DC voltage or current output that is linearly related
to the input.
The green input LED provides a visual indication that a signal is being
sensed by the input circuitry of the module. It also indicates the input
signal strength by changing in intensity as the process changes from
minimum to maximum.
If the LED fails to illuminate, or fails to change in intensity as the
process changes, check the module power or signal input wiring. The
red output LED provides a visual indication that the output signal is
functioning. It becomes brighter as the input and the corresponding
output change from minimum to maximum.
For current outputs, the red LED will only light if the output loop cur-
rent path is complete. For either current or voltage outputs, failure to
illuminate or a failure to change in intensity as the process changes
may indicate a problem with the module power or signal output
wiring. Note that it may be difficult to see the LEDs under bright
lighting conditions.
