SCXI-1120

National Instruments SCXI-1120 / SCXI-1120D 8-Channel Isolation Amplifier
Features

• 10 kHz Bandwidth
• For Voltage, Current, and Thermocouple Inputs Requiring Isolation
• 250 Vrms Isolation per Channel
• 4 Hz and 10 kHz Lowpass Filter Settings on Each Channel

The National Instruments SCXI-1120/D are 8-channel isolated analog input modules. These modules provide 250 Vrms of working isolation and lowpass filtering for each analog input channel. The architecture of the SCXI-1120/D is ideal for amplification and isolation of millivolt, volt, 0 to 20 mA, 4 to 20 mA, and thermocouple signals. The eight channels can be multiplexed into a single channel on the DAQ device and additional modules can be used to increase channel count.

The SCXI-1120/D analog inputs consist of 8 isolation amplifiers. These can be configured using jumpers for input ranges from ±2.5 mV to ±5 V (SCXI-1120) or ±5 mV to ±10 V(SCXI-1120D). Each channel also includes a lowpass filter that is jumper configurable for 4 Hz or 10 kHz(SCXI-1120), or for 4.5 or 22.5 kHz (SCXI-1120D).

These modules are CE certified as double insulated, Category II, for 250 Vrms of operational isolation.
