NI SCXI-1121 Product Details
Product Overview
NI SCXI-1121 is a 4-channel universal input module produced by National Instruments (NI) and designed for SCXI systems. It is widely used in various occasions where isolated sensor and signal input are required. The module provides independently configurable isolation amplifiers, filters, and excitation sources, which can be used to collect various types of input signals such as strain, thermal resistance, thermocouple, millivolt, volt, and current.

Main Features
High isolation: Each channel has an independent isolation amplifier to ensure signal integrity and system safety.
Flexible configuration: The amplifier gain, filter type, and excitation source can be flexibly configured according to different measurement requirements.
Versatility: Supports a variety of sensor and signal types, and has a wide range of applications.
Modular design: As part of the SCXI system, it can be combined with other SCXI modules to expand the functionality of the system.
Technical indicators
Number of channels: 4 channels
