SCXI’s voltage input modules are designed for signal conditioning and isolation of thermocouple, millivolt, volt and current signals. The following are several representative SCXI voltage input modules:

SCXI-1100: Designed for signal conditioning of millivolt, volt and current signals. All channels are multiplexed via a 4 Hz low-pass filter with jumper selection, providing multiple gain range options. All channels Multiplexes a single channel that controls a DAQ device, thereby increasing the number of channels in a DAQ system.
SCXI-1125: Designed for signal conditioning and isolation of thermocouple, millivolt, volt and current signals. It has isolated input channels, provides 300 Vrms operating isolation voltage, and 12 programmable gain Settings. Each channel also includes a 4 Hz or 10 kHz configurable low-pass filter. All channels Multiplexes a single channel that controls a DAQ device, thereby increasing the number of channels in a DAQ system.

When purchasing and using such modules, it is important to follow the appropriate safety specifications and operational guidelines to ensure safe and effective use.

The filter of the SCXI voltage input module can be configured as required.

Specifically, for the SCXI-1100, the filter configuration is selected by the jumper, and a filter of 4 Hz or 10 kHz can be selected. Each channel also includes a gain configurable amplifier with a choice of 12 programmable gain Settings.

For the SCXI-1125, it has an isolated input channel that provides 300 Vrms of operating isolation voltage. Each channel also includes a 4 Hz or 10 kHz configurable low-pass filter.

The function of these filters is to reduce noise interference and improve signal quality. According to the specific application scenarios and needs, the parameters of the filter can be flexibly selected and configured to achieve better signal processing effects.
