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.

Digital Filter
Index

This entry controls a first order filter
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 11 - 102 s
2 - 0.1 s 7 - 6.3 s 12 - 205 s
