Isolated Analog Output Modules
The following documents contain information that may help you as you
install and wire your module:
• National Electrical Code, published by the National Fire Protection
Association of Boston, MA
• IEEE Standard 518-1977, Guide for the Installation of Electrical
Equipment to Minimize Electrical Noise Inputs to Controllers from
External Sources
• IEEE Standard 142-1982, Recommended Practices for Grounding of
Industrial and Commercial Power Systems
• Noise Reduction Techniques in Electronic Systems, by Henry W. Ott;
published by Wiley-Interscience of New York in 1976
Avoiding Electrostatic
Damage
Guard against electrostatic damage by observing the following
precautions:
CAUTION
ELECTROSTATICALLY SENSITIVE COMPONENTS
•
Before handling the module, touch a grounded object to
rid yourself of electrostatic charge.
•
When handling the module, wear an approved wrist strap
grounding device.
•
Handle the module from the front, away from the
backplane connector. Do not touch backplane
connector pins.
•
Keep the module in its static-shield container when not
in use or during shipment.
Failure to observe these precautions can degrade the module’s
performance or cause permanent damage.
Determining Power
Requirements
The backplane of the SLC 500 system can provide both 5 Vdc and 24
Vdc power. The following table shows the maximum current consumed
by your module when using these power sources:
