SCXI-1121

National Instruments SCXI-1121 4-Channel Isolation Amplifier with Excitation
Features

• Wide Signal Input Range
• Shunt Calibration
• Isolated Analog Inputs
• Lowpass Filtering

The National Instruments SCXI-1121 is designed for a wide variety of sensor and signal inputs requiring isolation. The SCXI-1121 offers independently configurable isolation amplifiers, filters, and excitation sources for each channel. This module can acquire strain, RTD, thermocouple, millivolt, volt, 250 V, 0 to 20 mA, and 4 to 20 mA current input signals. The SCXI-1121 can multiplex their channels into a single channel of the DAQ device, and you can add modules to increase channel count. This module also offers parallel-mode operation.

The SCXI-1121 analog inputs consist of 4 isolated instrumentation amplifiers. Each channel can be independently configured using jumpers for input ranges of ±2.5 mV to ±5 V. A lowpass filter is included with each channel.

The SCXI-1121 is CE certified as double insulated, Category II, for 250 Vrms of operational isolation.
