National Instruments SCXI-1120D 8 Channel Isolation Amplifier

National Instruments SCXI-1120D 8 Channel Isolation Amplifier

The SCXI-1120D 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 offerparallel 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 ±5 mV to ±10 V. Each channel also includes a lowpass filter that is jumper configurable for 4.5 or 22.5 kHz. Each channel is individually isolated with a working common-mode voltage of 250 Vrms between channels or channel to earth. In addition, the SCXI-1120D is CE certified as double insulated, Category II, for 250 Vrms of operational isolation.
