18-4   4 To 20 Milliamp Output

XL™ Series

Figure 18-1    4 to 20mA Output Section

18.4   4 to 20 Hardware Connections / Wiring

Pins 12 and 13 of the terminal block provide connection points for the 4 to 20 milliamp output
signal.

Several instrumentation applications use sensors that provide an industry standard 4 to 20
milliamp output signal. The XL™ Series data logger / DCP can output a 4 to 20 milliamp signal
based on any of its inputs. For example, a user may want to connect a temperature probe to the
XL™ and convert the temperature value into a 4 to 20 milliamp output. A temperature probe on
Analog Channel 1 that produces a 0 to 5 volt output representing 0 to 100 degrees Celsius could
easily be setup to produce a 4 to 20 milliamp output that represents the 0 to 100 degrees. The
XL™ does not actually output a 4 to 20 milliamp signal, but rather controls the current in a loop
that is powered externally. Figure 2-11 shows a basic connection diagram.
