5. If you select analog inputs (AI), select the 250 Ohm Resistor
Installed option if you want the analog input in the current loop
mode.
6. Click Apply .
Note: Make sure you select the I/O types before you configure the I/O
using ROCLINK 800.
4.6 Analog Inputs (AI)
Analog inputs (AI) monitor current loop and voltage input devices. The
12-bit A/D signal input range is 0 to 100% EU value (where 0% EU is
643 counts and 100% EU is 3220 counts). You configure the analog
inputs using ROCLINK 800 software.
Notes:

The type E diagnostic analog inputs (logic voltage, battery voltage,
charge in, system milliamps, and battery temperature) are
not
designed to be configured or wired.

Select AI as the I/O Type for the selectable analog input/discrete input
when you configure it for use as an analog input. Refer to
Figure 4-5 .
The analog input (AI) channels are scalable, but typically measure either:

4 to 20 mA analog signal.

1 to 5 volts dc signal.
If required, you can calibrate the low end of the analog signal to zero.
The terminal blocks can accommodate size 16 to 24 AWG.
4.6.1 Wiring the Analog Inputs
The terminals for connecting the analog input wiring are shown in
Figures 4-6 and 4-7 .
The + terminal is the positive signal input and the GND terminal is the
signal common (

). These terminals accept a voltage signal in the 0 to 5
volt range. The GND terminal is internally connected to common so the
analog input channels function as single-ended inputs only. Use the
LOOP terminal to power external devices.
Wiring the Loop
Power Outputs
Using ROCLINK 800, you can configure the CPU module’s optional
I/O assembly to set the loop output power to 10 volts dc or 24 volts dc.
Note :
If the input voltage is greater than the 10-volt loop, then the loop
voltage equals the input voltage. For example, if the PWR IN is
14 volts dc and you select a 10-volt loop, the loop output equals
14 volts dc.
