Conventional (Polarity Reversal) Inputs 1 and 2
Two factors determine how the four NAC outputs respond to input:
•
Output protocol set on Switch S1 (refer to
Table 7
on page 17)
•
Setting of Position 0 of Switch S2 (refer to
Table 8
on page 18
Table 9
shows the output responses to the input on NAC inputs 1 and 2, based on the combined DIP switch
settings.
When an input is OFF, its polarity is reversed.
