About the Model 494.31 DI/O Breakout Box
The Model 494.31 16-Channel High-
Current DI/O Breakout Box provides a
terminal-plug interface and output-device
drivers that are monitored and controlled
by the Model 493.72 Digital I/O board.
The breakout box connects to the Model
493.72 Digital I/O board through two
cables, one for the digital inputs and one
for the digital outputs.
Device connections–each input/output
device connects to a terminal plug that is
inserted into one of the 16 input/output
sockets on the DI/O breakout box.
Power connections–you can connect an
external input and output power supply to
the Model 494.31 DI/O Breakout Box.
Input/output supply voltages are distributed
to the respective input/output sockets on
the digital I/O breakout box.
High-current, power-switching circuits–
each digital output includes a power
MOSFET that is controlled by the
corresponding opto isolator on the Model
493.72 Digital I/O board.
