Process Inputs (Mixed Mode)
The following process input configuration options are available in mixed input mode: 4-20 mA current
loop, 0-1.0 V voltage input, 0-2.0 V voltage input. Current loop readings are rounded to the nearest 0.1
mA and voltage readings are rounded to the nearest 10 mV. The process input is on pin 4 of the M12 5-
pin connector when in mixed input mode.
6.3.3.2.1
4-20 mA Device Connection
An input channel configured for 0-24 mA can measure the output of a 4-20 mA device. The
Current Loop interface measures the current into the selected input by converting it to a
voltage measurement across a fixed 49.9-ohm resistor. The connection diagram in mixed input
mode is similar to Figure 6 but only the input on pin 4 is valid for 4-20 mA measurements.
