Wiring Distance Calculation Example:
Suppose a system is configured with the following ANN-BUS modules:
• 2 ANN-80 Remote LCD Annunciators
• 1 ANN-S/PG Serial/Parallel Printer Interface Module
• 1 ANN-I/O LED Driver Module
The total worst case current is calculated as follows:
ANN-80 Current Draw
= 2 X 0.040 amps
ANN-S/PG Current Draw
= 1 X.0.040 amps
ANN-I/O Current Draw
= 1 X.0.200 amps
Total Worst Case Current Draw
= 0.080 amps
= 0.040 amps
= 0.200 amps
= 0.320 amps
Using this value and referring to the Wiring Distance Table 2.1 on page 31, it can be found that
the available options are:
 463 feet maximum using 22 Gauge wire
 1,172 feet maximum using 18 Gauge wire
 1,866 feet maximum using 16 Gauge wire
 2,953 feet maximum using 14 Gauge wire
