8.4.1 Analog inputs

The analog input to be set is selected in this display.
As standard, there are five analog inputs. The display shows each
input so that its physical location can be quickly identified.

Example

The AI1 analog input on the CU 362 (designated terminal 51) is
linked to the function "Level, pressure".
AI1 (CU 362) [51] and AI1 (IO351B-41) [57].

Analog inputs

Analog input, configuration

The analog input to be set is selected in this display.
Each analog input has its own display. The number of displays
depends on the number of analog inputs.

Example

1. Select input signal type, for example, 4-20 mA.
2. Select input value, for example, "Level, pressure".
3. Set sensor measuring range (minimum and maximum limits), for

example, 0.0 to 5.0 m.

If an analog input is disabled, the display only shows the
upper part, that is the input setting.

If the input is enabled, "Measured input value" is shown. A function
can be linked to an analog input in another display. CU
362 returns to the analog input setting display.
