The following table shows common input resistors and the ranges associated with each.
Input Resistor Turn-On Input Range Max Input Max Current
220
 1.8V 1.8 – 7.0V 8.5V 27mA
560

2.8V 2.8 – 10.6V 12.9V 20mA
1K
 4.1V 4.1 – 13.8V 16.9V 15mA
2.2K
 7.7V 7.7 – 20.0V 24.5V 10mA
3.3K

10.0V 10.0 – 24.0V 30.0V 9mA
4.7K
 15.2V 15.2 – 28.0V 35.0V 7mA
The turn-off voltage for all resistors is less than 1V.
Increasing the input resistor accordingly can increase the maximum input voltage. Because socketed DIP
resistors are utilized, they can easily be replaced with a different value. Sealevel can do this, if necessary.
The input circuits are not intended for monitoring 120-volt AC circuits. In addition to being too high
a voltage for the circuits, it is dangerous to have that high a voltage on the card.
