Rockwell Automation 1771-OA AC (120V) Output Module - Manual (Page 4)

AC Output Module 4
Publication 1771-IN080A-EN-P - November 2002
This module contains the circuitry necessary to control the on/off
status of eight user devices. The devices can be:
•
ac motor starters
•
indicators
•
solenoids
An output can drive an Allen–Bradley Size 4 motor starter, provided
its supply voltage does not drop below 92V ac. The maximum load
current the module can deliver is 1.5A per channel, not to exceed 6A
total per module.
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.

ATTENTION Preventing Electrostatic Discharge
This equipment is sensitive to electrostatic
discharge, which can cause internal damage and
affect normal operation. Follow these guidelines
when you handle this equipment:
•
Touch a grounded object to discharge potential
static.
•
Wear an approved grounding wriststrap.
•
Do not touch connectors or pins on component
boards.
•
Do not touch circuit components inside the
equipment.
•
If available, use a static–safe workstation.
•
When not in use, keep modules in appropriate
static–safe packaging.
