Description:
The National Instruments SCXI-1125, SCXI-1120, and SCXI-1120D are 8-channel isolated analog input modules. These modules share a common architecture, providing 250 to 300 V
rms
of working isolation and lowpass filtering for each analog input channel. This  architecture is ideal for amplification and isolation of millivolt, volt, 0 to 20 mA, 4 to 20 mA, and thermocouple signals. Each module can multiplex these eight channels into a single  channel of the DAQ device, and you can add modules to increase channel count. These modules also offer parallel mode operation for increased scanning rates.
The analog inputs of the NI-1120/D consist of eight isolation amplifiers. You can configure each amplifier using jumpers for input ranges from ±2.5 mV to ±5 V. With the SCXI-1327 high-voltage attenuator terminal block, the input range is extended to ±250 V. With the TBX-1316, the input range is extended to ±1000 VDC (680 V
rms
). Each channel also includes a lowpass filter that is jumper configurable for 4 Hz or 10 kHz. Each channel is individually isolated with a working common-mode voltage of 250 V
rms
between channels or channel to eart. In addition the SCXI-1120 is CE certified as double insulated, Category II, for 250 V
rms
of operational isolation.
