connections
Device connections–each output device connects to a terminal plug that is
inserted into one of the 16 output sockets on the digital I/O breakout box.
Power connections–you can connect an external power supply to connector
J21. This supply voltage is distributed to each of the 16 output sockets on
the digital I/O breakout box.
DI/O board connections
A cable from J4 on the Model 493.72 Digital I/O board connects all 16
digital-output signals to connector J20 on the Digital I/O Breakout box.
Each digital output on the Model 493.72 board has an opto-isolator that
controls the power to a device connected to the digital I/O breakout box.
