Description
The SCXI-1122, designated by part number 776572-22, falls under the category of SCXI & Legacy equipment. This model is a 16-Channel Isolated Transducer Multiplexer, designed to offer precise and isolated signal conditioning for a variety of transducers and sensors.
It features 16 isolated input channels along with 2 isolated excitation channels, designed to meet the needs of complex measurement systems. The SCXI-1122 supports both Two-wire scan mode and Four-wire scan mode operating modes, providing flexibility in connection and measurement strategies.
Compatibility with boards such as the Lab-PC+, MIO-16, SCXI-1200, and PC-LPM-16 makes the SCXI-1122 a versatile choice for integration into existing measurement and automation systems. Connection to these boards is facilitated through 50-pin male rear and 48-pin female front connectors, ensuring a reliable and straightforward setup.
The input impedance of the SCXI-1122 is 1 GΩ (power on), which changes to 100 kΩ (power off), allowing for flexible accommodation of various signal types. The device boasts a bandwidth of 4 Hz (-10 dB) or 4 kHz, which is software selectable, providing adaptability for different application requirements. Additionally, it includes an integrated 3-pole RC filter with a 4 Hz (-10 dB) cutoff frequency, enhancing signal quality by reducing noise.
The bandwidth NMR is rated at 60 dB at 4 Hz, indicating the device’s effective noise reduction capabilities at low frequencies. It also has 2 output channels, with a voltage level of 3.333 V ±0.04%, ensuring precise excitation or signal output for connected transducers.
