What This Option Board
Provides
Optional 115V AC to 24V DC I/O Converter
Circuit Board
The 115V AC to 24V DC I/O Converter circuit board
convert 115V AC digital input signals to 24V DC digital input signals in
order to interface with the standard digital I/O terminal blocks on the
PowerFlex DC drive Control board.
The card consists of:
• Eight (8) opto isolated 115V AC digital inputs
• Eight (8) interface outputs for the digital inputs on Control board of the
(2)
drive
• Two (2) input terminals for the 24V DC power supply voltage
