Description
The SCXI-1120, part number 181695G-01 (also known as 776572-20), falls under the category of SCXI & Legacy equipment. This model is designed with 8 isolated input channels, ensuring versatile and secure data acquisition capabilities. Each channel is capable of working with an isolation level of up to 250 Vrms, providing an additional layer of safety and signal integrity.
The SCXI-1120 offers a wide range of input ranges, including gains of 1, 2, 5, 10, 20, 50, 100, 200, 250, 500, 1,000, and 2,000, catering to a broad spectrum of signal amplitudes. This flexibility allows users to precisely capture signals of varying strengths without distortion. The module outputs signals in a range of ±5 V, compatible with most data acquisition systems.
Additionally, the device features lowpass filter options of either 4 Hz or 10 kHz, enabling users to effectively minimize signal noise and improve measurement accuracy. The SCXI-1120 supports both parallel-output and multiplexed-output modes, providing flexibility in data transfer and synchronization with other devices.
Connection to the SCXI-1120 is facilitated through 50-pin male ribbon-cable rear and 32-pin DIN C male front connectors, ensuring easy integration into existing setups. The unit is designed to operate within a temperature range of 0 to 50 °C, and its compact dimensions of 1.2 x 6.8 x 8.0 inches make it suitable for a variety of working environments.
Despite its obsolete status, as announced by National Instruments, the SCXI-1120 remains available for purchase and repairs through Apex Waves. Moreover, calibration services are readily available, with options for NIST accredited calibrations or basic in-house calibration, ensuring that the device maintains its accuracy and reliability over time.
