I/O Wiring

6-5-2 Output Wiring

Wire the analog output as shown in the following illustration. Use shielded
twisted-pair cables to connect field devices.
The 4 to 20-mA current output is always output even when a voltage output (0 to
10 V or –10 to 10 V) has been set.
When using both the current and voltage outputs, the total output current must
be 21 mA or less.
