Description
The SCXI-1122 is designated with the part number 776572-22 and falls under the SCXI & Legacy category. This device is a 16-Channel Isolated Transducer Multiplexer designed for versatile applications. It features 16 isolated channels along with 2 isolated excitation channels, providing a broad range of connectivity options for various transducers.
When it comes to operation modes, the SCXI-1122 offers flexibility with its Two-wire and Four-wire scan capabilities, ensuring compatibility with different sensor types. This multiplexer is designed to work with several compatible boards, including Lab-PC+, MIO-16, SCXI-1200, and PC-LPM-16, making it a versatile choice for integrating into existing setups.
The input impedance of the SCXI-1122 is a robust 1 GΩ when powered on, and 100 kΩ when powered off, ensuring minimal interference with the measured signals. Its bandwidth can be selected between 4 Hz (-10 dB) or 4 kHz, depending on the application’s requirements, providing flexibility in signal processing.
This device includes a 3-pole RC filter with a 4 Hz (-10 dB) cutoff and 60 dB at 4 Hz NMR, offering effective signal conditioning to improve measurement accuracy. It also features 2 output channels with an output voltage and current of 3.333 V ±0.04% and 1.0 mA ±0.04%, respectively, ensuring precise control over the connected transducers.
Connectivity is facilitated through 50-pin male (rear) and 48-pin female (front) connectors, offering convenient and flexible connection options for both input and output signals. This makes the SCXI-1122 an ideal choice for a wide range of applications requiring high isolation, precise control, and flexible connectivity.
