7.5 Discrete Output Wiring
Discrete output (DO) wiring depends on whether you are wiring terminals 3 and 4 (Channel B) or
terminals 5 and 6 (Channel C), and also on whether you have configured the terminals for internal or
external power. The following diagrams are examples of proper wiring for these configurations:
•
Channel B, internal power – Fgiure 7-9
•
Channel B, external power – Figure 7-10
•
Channel C, internal power – Figure 7-11
•
Channel C, external power – Figure 7-12

Note: See Figure 7-13 for output voltage
versus load information.

3–30 VDC
Note: See Figure 7-15 for recommended
resistor versus supply voltage.
Excessive current will damage the transmitter.
Do not exceed 30 VDC input. Terminal current must be
less than 500 mA.
