Chapter 1 Selection Considerations
PowerFlex 755T I/O Option Modules
The PowerFlex 755T product main control board has one digital input that is
typically used for hardware ENABLE. Optional 750-Series I/O modules must
be added if additional digital and analog I/O is required.
Refer to the PowerFlex 750-Series Products with TotalFORCE Control
installation instructions, publication 750-IN100
, for detailed information
about option modules.
Chapter 2 Control Devices shows an example of using a 20-750-2263C-1R2T,
24V DC I/O module to emulate a typical hardware control function used with
a PowerFlex 700S drive.

Note: The 115V AC Digital Inputs can withstand 2 mA of leakage current without turning on. If an
output device has a leakage current greater than 2 mA, a burden resistor is required. A 68.1 K
resistor with a 0.5 W rating should be used to keep the 115V AC output below 2 mA.
