5.3.1 Signal Output
Figure 8: Wiring of the Signal Output (mA or V)
The signal output can be configured either as current or as voltage
output.
The minimum load impedance for the 0 to 5 V output must be
100 kΩ.
The maximum current loop impedance for the 0/4 to 20 mA output
can be 500 Ω, and the power supply and loop impedance must be
matched as shown below.
