Rockwell Automation 1762-IA8 MICROLOGIX 120 VAC INPUT MODULE - Manual (Page 8)

8 MicroLogix™ 1762-IA8 120V ac Input Module
1762-IN002A-US-P
Input Wiring
Basic wiring
(1)
of input devices to the 1762-IA8 is shown below.
A write-on label is provided with the module. Mark the identification of each
terminal with permanent ink, and slide the label back into the door.
(1) A current limiting resistor can be used to limit inrush current; however, the operating characteristics of the
ac input circuit will be affected. If a 6.8K
Ω
resistor is placed in series with the input, the inrush current is
reduced to 35 mA. In this configuration the minimum on-state voltage increases to 92V ac.
Before adding the resistor in a hazardous environment, be sure to consider the operating temperature of
the resistor and the temperature limits of the environment. The operating temperature of the resistor
must remain below the temperature limit of the environment.
!
ATTENTION: Be careful when stripping wires. Wire fragments
that fall into a module could cause damage when power is applied.
Once wiring is complete, ensure the module is free of all metal
fragments.
