Product Dimensions：

The SCXI-1120/D has eight isolated input channels. The SCXI-1120 is a

module for signal conditioning of thermocouples, volt sources, millivolt sources, 4 to 20 mA current sources, and 0 to 20 mA process-current sources. If external excitation is provided, thermistors, RTDs, and strain gauges can also be measured. The SCXI-1120D is a module for signal conditioning and isolating volt sources, millivolt sources, and current sources that require a bandwidth of up to 20kHz. If you provide external excitation, you can use strain gauges and other vibration sensors. The SCXI-1120/D can operate in two output modes—in the parallel-output mode with all eight input channels connected in parallel to eight DAQ device channels, or in the multiplexed-output mode with all eight channels multiplexed into a single DAQ device channel.

The SCXI-1120/D operates with full functionality with the National

Instruments MIO, 1200 Series, and Lab PC+ devices. You can use the

Lab-NB, the Lab-PC, the Lab-LC, and the PC-LPM-16/PnP devices with

the SCXI-1120/D, but these devices cannot scan the module when it is

configured in the multiplexed-output mode. These devices can perform only single-channel reads in this mode. You can multiplex several SCXI-1120/D modules into a single channel, thus greatly increasing the number of analog input signals that can be digitized.

The addition of a shielded terminal block provides screw terminals for easy signal attachment to the SCXI-1120/D. In addition, a temperature sensor for cold-junction compensation (CJC) of thermocouples is included on the terminal block. This cold-junction reference (CJR) is either multiplexed along with the eight channels or connected by jumpers to a different channel of the DAQ device.
