Important: You can use an AC (220/240 V) Output Module (cat. no. 1771sc-
OMI16) to drive terminals on the 1771sc-IMI16, as shown in Figure 3. Use the
same AC power source to power both modules to ensure proper phasing
and prevent module damage. (Note: the 1771sc-OMI16 is an isolated output
module.)
