SC-2060 Board
This chapter describes the SC-2060 board in detail including function, compatibility,
specifications, mounting, and connection.
With the SC-2060 optically isolated digital input board, you can easily connect field digital
signals to a computer equipped with a National Instruments data acquisition board. With the
appropriate SC-205X Series board, the SC-2060 can have input isolation for the National
Instruments data acquisition boards for the Macintosh II, IBM PS/2 Micro Channel, and
PC/XT/AT computers.
Each SC-2060 board has screw terminals for eight input channels. Each input screw terminal is
optically isolated from the digital I/O pins of the data acquisition board and from the other input
terminals up to a working voltage of 300 Vrms. This feature is useful in many situations,
especially in industrial and other monitoring environments where common mode voltages are
present.
