AC/DC (120V) Input Module

Publication 1771ĆIN023B-EN-P - August 2002
The ac/dc input module is shipped in static-shielded packaging to
guard against electrostatic discharge damage. Observe the following
precautions when handling the module.
Electrostatic Discharge Damage
!
ATTENTION
Electrostatic discharge can damage
integrated circuits or semiconductors if you touch
backplane connector pins. Follow these guidelines
when you handle the module:
•
Touch a grounded object to discharge static
potential
•
Wear an approved wrist-strap grounding device
•
Do not touch the backplane connector or
connector pins
•
Do not touch circuit components inside the mod-
ule
•
If available, use a static-safe work station
•
When not in use, keep the module in its original
static-shielded packaging
The 1771-IAD Series D module is compatible with all chassis except
the 1771-A1, 1771-A2 and 1771-A4 chassis. Make sure no other
input module or single card block transfer module is placed in the
same module group when using 2-slot addressing. Any discrete
output module may be used within the same module group.
Your module receives its power through the 1771 I/O chassis
backplane from the chassis power supply. The module requires
195mA from the output of this supply. Add this to the requirements
of all other modules in the I/O chassis to prevent overloading the
chassis backplane and/or chassis power supply.
