Analog Input Modules (Ani0-8) - ABB ControlIT 53MC5000 Instruction Manual

5.4 ANALOG INPUT MODULES (AI0-8)
The Analog Input Modules (AI0-8) are used to configure the characteristics of each input. Inputs AI4 through AI8 are active only if the ap-
propriate hardware option is installed. The nine Analog Input Modules are listed in Table 5-4. Each module can be configured sepa-
rately.

Title Definition
Analog Input This is the value in engineering
units of the measured input after all
signal conditioning has been
applied.
Engineering This value determines the upper
Span range the analog input represents
in engineering units. The upper
range value equals Engineering
Zero plus Engineering Span.
Engineering This is the lower range value.
Zero
Digital Filter This entry controls a first order filter
Index that is applied to the input signal.
The time constant is entered as an
index value as follows:
0 - None (no effect),
1 - 0.05 s 6 - 3.1 s
2 - 0.1 s 7 - 6.3 s
3 - 0.3 s 8 - 12.7 s
4 - 0.7 s 9 - 25.5 s
5 - 1.5 s 10 - 51.1 s
Signal Base This value specifies the signaling
range of the input.
0 - 4-20 mA (1 - 5V)
1 - 0-20 mA (0 - 5V)
