SC-2071 Board
This chapter describes the SC-2071 board in detail, including function, compatibility,
connection, mounting, and applications. This chapter also discusses working with
thermocouples.
The SC-2071 is a general-purpose termination breadboard that makes it easy to connect to all
Lab/1200 device I/O signals; add analog input signal conditioning, such as filters, dividers, and
thermocouple compensation; and build external, custom timing, analog, and digital circuits.
The SC-2071 board is used with the National Instruments Lab/1200 devices for the Macintosh,
IBM PC/XT/AT, and compatible computers.
The SC-2071 board has screw terminals for eight single-ended input channels. Open component
positions at each analog input facilitate the addition of user-selected signal conditioning. The
SC-2071 board has an onboard temperature sensor that can be optionally jumpered to channel 0
for thermocouple cold-junction compensation. With open component positions in the input
paths, you can insert user-supplied resistors and capacitors for conditioning the eight single-
ended analog input signals. A 4 by 1.5 in. general-purpose breadboard area is also included.
The SC-2071 board also has screw terminals for all of the other signals from the DAQ device.
With these terminals, the board easily connects to digital, timing, and trigger signals. The
SC-2071 has two 50-pin I/O connectors, J1 and J2. Connector J2 is designated for daisy-
chaining DAQ signals. Figure 3-1 shows the parts locator diagram for the SC-2071 board.
