Analog Output
(4-20 mA)
The 4-20 mA linear
current output can be
configured with
ModWorX™ Pro
software to represent
any parameter in the
holding registers. This
output requires a two-
conductor cable to be
connected to an 8 to 30
VDC power supply (volt-
age required is depen-
dent on loop resistance)
and an analog readout
device to be located in
the remote location.
The graph above shows
the minimum voltage
For example, if a power
supply voltage of 24
volts is available to
power the current loop,
the maximum load
resistance would be 800
ohms.
