ATTENTION
Do not attempt to increase load current or wattage
capability beyond the rating by connecting two or
more outputs in parallel. The slightest variation in
output relay switching time may cause one set of
contacts to switch the total load current.
You can use the output of a 1771-OWNA output module to drive an
input of a 120V ac input module (1771-IA, -IA2, -IAD) to indicate
status of turning on a motor starter as shown below, for example, but
you must connect a 15K, 2W resistor between the output and L2
(common). Inputs configured with the output module are not isolated
from each other.
