Power Supply Connections for Isolated Outputs

Power Supply Connections for Non-Isolated Outputs

POWER SUPPLY CONNECTIONS

Figure 4

Figure 5

Isolated Power Supply connections are available so that
the Control Outputs are isolated from the input circuitry.
When using Isolated Control Outputs, a second 15-24
VDC power supply is needed (See Figure 4). This
setup is most commonly used to prevent the mixing
of power supply commons together when connecting
analog control outputs to a motor drive (Refer to
SPECIFICATIONS).

If Isolated Control Outputs are not needed, the Isolated
+VDC and ISO Common must be connected to +24
VDC and DC common inputs, respectively (See Figure
5).
