Rockwell Automation 1771-OP Protected AC (120V) Output Module Installation Instructions - Manual (Page 4)

Protected AC Output Module 4
Publication 1771-IN077A-EN-P - October 2002
An output can drive an Allen–Bradley Size 5 motor starter, provided
its supply voltage does not drop below 92V ac. The maximum load
current the module can deliver is 2A per channel, not to exceed 6A
total per module.
ATTENTION
!
When using a remote I/O system with a PLC
processor, use only the 1771-AS or 1771-AR
remote I/O adapter module which is series B or
later. These remote I/O adapters add additional
capability for shorted data bus detection. Failure
to use series B or later remote I/O adapters may
result in damage to equipment and/or personal
injury.
The output module is powered by the power supply connected to the
I/O chassis backplane. The module requires a maximum current of
210mA from the +5V dc output of this supply. Total the current
requirements of this module with the other modules in the I/O
chassis to avoid overloading the supply or the I/O chassis backplane.
Group your modules to minimize adverse effects from radiated
electrical noise and/or heat. We recommend the following:
•
Group analog input and low voltage dc modules away from ac
modules or high voltage dc modules to minimize electrical noise
interference.
•
Place analog input modules and other I/O modules sensitive to
heat away from slot power supplies and rack controllers to
minimize adverse heat effects.
The 1771–OP module is a modular component of the 1771 I/O
system requiring a properly installed system chassis. Refer to
publication 1771–IN075 for detailed information on acceptable
chassis, proper installation and grounding requirements. Limit the
maximum adjacent slot power dissipation to 10W maximum.
