IMPORTANT
• This diagram shows the sensors operation from a common
power supply. Separate power supplies for each circuit can
be used.
• The resistor (R1) value depends on the power supply value
(VS). The table on page 17 provides the resistor values for
typical power supply values. These resistors must be
located at the module end of the cable.
• The pull-up resistor (R2) value depends on the power
supply value (VS). The table on page 16 provides the
resistor values for typical power supply values. These
resistors must be located at the sensor end of the cable.
