Module Inputs
1. External resistors are needed if not internal to the encoder. The pull-up resistor (R) value depends on
the power supply value. The table below shows resistor values for typical supply voltages. To calculate
the resistor value, use one of the following formulas:
For 5V dc jumper position: R =
(V
cc
- V
min
)
I

For 24V dc jumper position: R =
(V

- V
