NI SCXI-1125 Product Overview

The NI SCXI-1125 module is designed for measuring various types of analog signals in harsh industrial environments.It provides 8 isolated analog input channels,each with a working isolation voltage of 300Vrms,as well as programmable gain and filter settings.The module can be used with other SCXI modules and NI’s data acquisition system to build a flexible and scalable measurement system.

Main Features

8-channel isolated analog input:NI SCXI-1125 provides 8 independent analog input channels,each with high isolation voltage,which can effectively protect the measurement system and the device under test.

High isolation voltage:Each channel has a working isolation voltage of 300Vrms,which is suitable for signal measurement in high voltage environments.

Programmable gain:Each channel has 12 programmable gain settings,which can flexibly adjust the gain as needed to adapt to signal measurement of different ranges.

Low-pass filter:Each channel is equipped with a configurable low-pass filter of 4Hz or 10kHz,which can effectively filter out high-frequency noise and improve measurement accuracy.

Thermocouple measurement:Supports various types of thermocouple measurements,can directly measure temperature signals,and convert them into corresponding voltage values.

Modular design:Complies with SCXI standards and can be used in combination with other SCXI modules to build a customized measurement system.
