Rockwell Automation 1771-OD AC (120V) Isolated Output Module Installation Instructions - Manual (Page 5)

AC (120V) Isolated Output Module 5
Publication 1771-IN078A-EN-P - October 2002
The isolated output module is powered by the power supply
connected to the I/O chassis backplane. The module requires a
maximum current of 225mA 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.
The 1771–OD 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.
