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
(2.5W minimum) 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.
