AC/DC (220V) Input Module Cat. No. 1771-IMD Series B
Publication 1771Ć5.27
Important: You can use an AC (220V) Output Module (cat. no.
1771-OMD) to directly drive terminals on an AC/DC
(220V) Input Module (cat. no. 1771-IMD) as shown
below.
You can also use a 1771-OM Output module to drive an AC/DC
(220V) Input Module (cat. no. 1771-IMD) but you must connect a
10K ohm, 10W resistor between the output terminal and L2
(common) as shown below. Use the same ac power source to
power both modules to ensure proper phasing and prevent
module damage.
