AC (24V) Output Module

Publication 1771Ć5.41 - May 1996
Important: You can use an AC (24V) Output Module (cat. no.
1771-OND) to directly drive terminals on an AC (24V)
Input Module (cat. no. 1771-IND) (Figure 3). You can
also use a 1771-OND Output module to drive an AC
(24V) Input Module (cat. no. 1771-IN) but you must
connect a 250 ohm, 5W resistor between the output
terminal and L2 (common) as shown in Figure 3. Use
the same ac power source to power both modules to
ensure proper phasing and prevent module damage.
