SC-2072 Board
This chapter describes the SC-2072 board in detail, including function, connection, mounting,
and soldering/desoldering.
The SC-2072 board comes in two configurations—the SC-2072 comes without a DC-to-DC
converter, whereas the SC-2072D comes with a DC-to-DC converter. Unless the text denotes
otherwise, all references to the SC-2072 board apply to both configurations.
The SC-2072 is a general-purpose termination breadboard that makes it easy to connect to all
NB Series, MC Series, PC Series, AT Series, Lab/1200 Series, and the PC-OPDIO-16 DAQ,
digital I/O, and timing devices (except for the NB-A2000 and the EISA-A2000), and some
DAQCards; add analog input signal conditioning, such as filters and dividers; and build external,
custom timing, analog, and digital circuits.
The SC-2072 board is used with the National Instruments DAQ devices for the Macintosh,
IBM PS/2 Micro Channel, and PC/XT/AT and compatible computers.
The SC-2072 board has screw terminals for all 50 signals present on the I/O cable. These
terminals can be used for easy connection to the analog, digital, timing, and trigger signals from
the expansion board. In addition, the SC-2072 board has one set of 12 terminals that can be used
for connection of 12 external signals.
For digital power connections, one set of three terminals can be used to connect digital power
and ground inputs to an external power supply. On the base model of the board, the SC-2072, a
second set of three terminals connects positive, negative, and common power inputs for
powering onboard analog circuitry. The second model of the board, the SC-2072D, comes
equipped with a DC-to-DC converter that can be used to power analog circuitry (see Power
Connections later in this chapter). A breadboard area of 2.4 by 4.6 in. is also included.
The SC-2072 can be used in conjunction with the other signal conditioning accessories,
including the SC-206X Series boards and SSR Series boards. An SC-205X Series cable adapter
board must be used for connection of multiple signal conditioning accessories.
Figure 4-1 shows the parts locator diagram for the SC-2072 board. Figure 4-2 shows the parts
locator diagram for the SC-2072D board.
