4-20 mA Output Parameters The 4-20 mA output parameters define the characteristics of the two 4-20 mA
output signals. The parameters are the same for each output.
4-20 mA Parameters
Parameter Name Description Options/Comments
Enable Enables/disables the 4-20 mA output.
Measurement Sets the type of measurement and the channel that
the 4-20 mA output signal will track. Options: Ch1 / Ch2 Overall
Ch1 / Ch2 Tracking
Magnitude *
Ch1 / Ch2 Band *
Speed
Ch1 / Ch 2 DC Bias
Important: The tracking and band
measurement selections depend on
which filter measurement (Bandpass
Filter or Tracking Filter) is selected.
See Aeroderivative Measurement
Parameter on page 55.
For example in the XM Serial
Configuration Utility, if you selected
Bandpass Filter for channel 1 and
Tracking Filter for channel 2, then
the measurement selection would
include "Ch1 Band" and "Ch2 Tracking
Magnitude" but not "Ch2 Band" or
"Ch1 Tracking Magnitude."
Min Range The measured value associated with the 4 mA. Same measurement unit as Output
Data Unit selection for the specified
channel.
Max Range The measured value associated with the 20 mA.

IMPORTANT
Measured values between Min Range and Max Range are
scaled into the range from 4.0 to 20.0 to produce the
output value. The Min Range value does not have to be
less than the Max Range value. If the Min Range value is
greater than the Max Range value, then the output signal
is effectively inverted from the input signal.
