The DMD4380 accepts a dc voltage
or current input and provides an
optically isolated dc voltage or
current output that is linear to the
input. It provides filtering, amplifies,
and converts the input signal to
the selected dc voltage or current
output that you select. The 3-way
1200V isolation eliminates ground
loops, common mode voltages and
greatly reduces noise pick-up.
Standard features include a 15 Vdc
loop power supply and a 20 Vdc
loop supply for the output. The
power supplies can also be wired
to sink or source which allows
DMD4380,
shown smaller than
actual size with standard
DIN rail (sold separately).
the DMD4380 to be used with
any combination of powered or
unpowered mA inputs and powered
or unpowered mA outputs including
passive mA devices. Features
such as red and green LEDs that
vary in intensity to show input
and output activity and an output
test button help make set-up and
troubleshooting fast and easy.
