XL™ Series
4 To 20 Milliamp Output 18-1
18.1 Introduction
These options allow the XL™ to use any of its input signals as a data source to generate a current
output simulating a 4 to 20 mA sensor. The XL does not actually generate the current in the loop
but controls the current in a loop that is externally powered. The 4 to 20 milliamp connection
points are optically isolated from the rest of the XL circuitry.

Current Milliamp Output: xx.xx
mA Output = XX.XX
This screen shows what the output current should be if it were measured with a current meter. It
should be in the range of 4 to 20 milliamps. This is based on the value of the data source, the
Max value and the Min value.
If a current meter is used to verify the output and it does not match this value then check the
