PowerFlex DC 115V AC to 24V DC I/O Converter Circuit Board
The 115V AC to 24V DC I/O converter board allows you to convert 115V AC
digital input signals to 24V DC digital input signals to interface with the
standard digital I/O on the PowerFlex DC drive control board. This board
provides these additional I/O signals.
• Eight opto isolated 115V AC digital inputs
• Eight interface outputs for the digital inputs on control board of the drive
• Two input terminals for the 24V DC power supply voltage
Table 30 - Recommended Signal Wire Size
A 75 x 2.5 x 0.4 mm (3.0 x 0.1 x 0.02 in.) flathead screwdriver is recommended
for connecting wire to the terminal block inputs. Strip the ends of the cables to a
length of 6.5 mm (0.26 in.).
