PowerFlex DC Drive and Field Controller Technical Data
PowerFlex DC Drives and Field Controller I/O Signal and Control Wiring
Eight digital inputs, four digital outputs, three analog inputs, and two analog outputs are available on the standard I/O terminal blocks that
are provided with the drive. One digital input (1…8) must be configured for “Enable”.
More digital and analog I/O is available when using the optional I/O expansion circuit board. See Appendix F - ‘Optional Analog and Digital I/O
Expansion Circuit Board,’ in the PowerFlex Digital DC Drive User Manual, publication 20P-UM001 , for more information. You can also use the
optional 115V AC converter circuit board to convert 115V AC to 24V DC digital inputs signals to interface with the digital inputs on the standard
I/O terminal blocks. See Appendix G Optional 115V AC to 24V DC I/O Converter Circuit Board in the PowerFlex Digital DC Drive User Manual,
publication 20P-UM001 , for more information. All I/O terminal blocks are on the control board.

Important: 0…20 mA or 4…20 mA operation requires
that switch S9, S10, and S11 on the Control board be in
the “Off” position. Drive damage can occur if the
switch is not in the correct position that is based on
the type of input signal. See “DIP switch and Jumper
Settings” in the PowerFlex Digital DC Drive User
Manual, publication 20P-UM001 .
