DC CURRENT OR VOLTAGE 1 INPUT 3 OUTPUTS

SELECTION GUIDE

M100-DM3 One input three outputs


TYPICAL APPLICATIONS

The M100-DM3 takes 1 DC Input and provides 3 isolated
outputs all directly proportional to the input. The outputs
can all be of the same D.C. Value or can be different.
Typically this product is used to prevent earth loops
between measuring devices. For example the M100-DM3
could have its input signal provided by a M100-WA4 watt
transducer with 4-20mA output. The 3 outputs from the
M100-DM3 could be as follows.
Output A = 4-20mA fed to a PLC.
Output B = 0-20mA fed to a analogue meter scaled in kW.
Output C = 1-5 volt fed to a chart recorder.
The isolation between the Input / Output / Case is 1.5kV
and the isolation between each output is 500 volts.
