Selectable Contact Output Module Cat. No. 1771-OWN
Publication 17715.37 - October 1995
!
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 1771-OWN 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.
