ohm input impedance. Regardless of input configuration, each input is
individually isolated to ± 100V DC or 70V RMS AC.
A block diagram of the receiver is shown in Figure 295 .

Non-Isolated Process Outputs
The drive supplies four non-isolated -10/0/+10 V outputs for customer use.
These outputs can drive loads with impedances as low as 600 ohms. These
outputs are all referenced to the Drive AGND and therefore should be isolated if
they are required to drive outside the PowerFlex “C” frame enclosure.
