Pull-up resistor

Note: See Figure 3-12for recommended resistor versus supply voltage.

CAUTION

Excessive current will damage the transmitter.

Do not exceed 36 VDC input. Terminal current must be less than 500 mA.

3.4.3Discrete output wiring

Discrete output wiring depends on whether you will use internal or external power. The following diagrams are examples of proper wiring for these configurations:

•Internal power – Figure 3-9

•External power – Figure 3-10
