The available AI options are listed in the following table:
Option Range Description
AI type 0-1 mA
±1 mA
0-20 mA
4-20 mA
0-50 mA
±10 V
The AI module type. When connected to the device,
shows the actual AI type read from the AI module.
Zero scale 0/4 mA Defines the low engineering scale (in primary units) for
the analog input corresponding to a lowest (zero) input
current (0 or 4 mA, or 0 V)
Full scale 1/20/50 mA, 10V Defines the high engineering scale (in primary units) for
the analog input corresponding to a highest input
current (1, 20 or 50 mA, or 10 V)
Dec. Places The number of decimal digits in a fractional part of the
scaled engineering value
Value label An arbitrary name you can give the analog input value
NOTE:
Always save your AI setup to the site database in order to keep the labels you gives
the analog inputs. They are not stored in your device.
Scaling Non-directional Analog Inputs
When programming scales for non-directional analog inputs with a 0-1mA, 0-20mA or
4-20mA current option, provide both zero and full engineering scales. An example is
shown in the picture above for the 0-20 mA analog inputs. Each of the scales
operates independently.
