12 SLC 500 ™ Isolated Analog Input Modules
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 current consumed by your
module when using these power sources:
Table 6. Backplane current consumed
Catalog Number 5 Vdc 24 Vdc
1746sc-INI4i 4 4 0 mA typical 0 mA
1746sc-INI4vi 5 5 0 mA typical 0 mA
Use this table to calculate the total load on the system power supply. For
more information, see the system Installation and Operation Manual.
Important — Your module does not supply power for input devices. You
must supply the appropriate power.
