输入模块是否需要24v电源分以下情况：

SCXI-1102自供电。当模块自带24V电源容量能够满足供电要求时，不使用外部24V电源供电。

外部供电。SCXI-1102模块输入输出或其中的输入或输出采用外部24V电源供电，此时注意模块自带24V电源与外部24V电源要各自独立。

输出模块。如果输出触点为晶体管型，输出电源必须使用24V直流电源1。

此外，四线制输入模块不需接入24伏电源线；二线制输入模块需接入24伏电源线。

SCXl-1102SCXI Voltage input module

32 channel, ±10V, 2Hz filter, voltage input module - for SCXI- The SCXI-1102 is designed for signal conditioning of thermocouple, millivolt, volt and current signals. It has a cold-end compensation sensor for temperature measurement and multiple gain ranges based on a 2Hz cutoff frequency filter. All channels Multiplexes a single channel that controls a DAQ device, thereby increasing the number of channels in a DAQ system.

A voltage input module is a device that converts an external voltage signal into a digital signal that can be read by a computer. It usually has the characteristics of high precision, high speed and high reliability, and can adapt to a variety of complex and harsh industrial environments. Voltage input module has a wide range of applications, such as power, petroleum, chemical, steel, coal and other industries have a wide range of applications. The voltage input module CAN be connected to the device through different interfaces, such as RS-485, RS-232, CAN and other communication interfaces, and can also be connected to analog signals through analog input interfaces. The voltage input module can collect various types of voltage signals, such as DC 4~20mA, DC 0~10V and other signals, and can also collect analog signals such as temperature, pressure, and flow. SCXI-1102 voltage input module models and specifications are very many, different brands and models of voltage input modules have different characteristics and functions, users can choose according to their own needs for their own module.

Whether the input module needs 24v power supply can be divided into the following situations:

The SCXI-1102 is self-powered. When the 24V power supply capacity of the module meets the power supply requirements, do not use an external 24V power supply.

External power supply. The input and output of the SCXI-1102 module or the input or output of the SCXI-1102 module are powered by an external 24V power supply. In this case, note that the built-in 24V power supply of the module and the external 24V power supply are independent.

The output module. If the output contacts are transistor type, the output power supply must use 24V DC power 1.

In addition, the four-wire input module does not need to be connected to the 24-volt power cord; The two-wire input module must be connected to a 24-volt power cable.
