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 – Figure 6-9
Channel B, external power – Figure 6-10
Channel C, internal power – Figure 6-11
Channel C, external power – Figure 6-12
Figure 6-9
Discrete output 1 – Terminals 3 & 4 (Channel B) – Internal power

Total load
Note: See Figure 6-13 for output 
voltage versus load information.

3–30 VDC
Note: See Figure 6-15 for recommended 
resistor versus supply voltage.
CAUTION
Excessive current will damage the transmitter.
Do not exceed 30 VDC input. Terminal current must be less than 500 mA.
