62 Configuration Parameters
4-20mA Output Parameters
The 4-20mA output parameters define the characteristics of the two 4-20mA
output signals. The parameters are the same for each output.
4-20mA Parameters
Parameter Name Description Values/Comments
Enable Enables/disables the 4-20 mA output.
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.

Check to Enable Enabled
Clear to Disable Disabled
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.
IMPORTANT
The 4-20mA outputs are either on or off. When they are
on, the 4-20mA outputs overshoot the 4 and 20mA limits
by 10% when the measurement exceeds the minimum and
maximum range. This means the minimum current
produced is 3.6mA and the maximum current produced is
22mA.
When the 4-20mA outputs are off, they produce a current
approximately 2.9mA. The 4-20mA outputs are off under
the following conditions:
• The 4-20mA outputs are set to "Disable" (see Enable
above).
• The module is in Program mode.
• A transducer fault occurs that affects the corresponding
measurement.
