描述
主要产品详情及功能
模拟输入模块：其主要功能是将现场设备的模拟信号转换为控制器可处理的数字数据。这些模拟信号通常来自测量温度、压力、流量、液位等物理量的传感器。
通道：DSAI130A具有16个模拟输入通道，使其能够同时监控工业过程中的大量模拟传感器。
输入信号类型：支持常见的工业模拟输入范围，包括：
+/-10V（电压信号）
+/-20mA（电流信号）
这种多功能性使其能够与各种工业传感器和变送器兼容。
高精度：该模块以其高精度而闻名，通常为0.025%。这种精度对于需要精确测量和控制过程变量的应用至关重要。
差分输入：“差分输入”功能意味着它测量每个通道两个输入端子之间的电压差，这有助于降低共模噪声并提高嘈杂工业环境中的信号完整性。
兼容性：DSAI130A(3BSE018292R1)是旧款DSAI 130(57120001-P)的升级版。它设计用于与ABB的AC410、AC450和AC460等标准过程控制器配合使用，尤其适用于共模电压(CMV)小于或等于50V的情况。对于旧款安全控制器(MasterPiece 2×0)或CMV大于50V的情况，可能需要将旧款DSAI 130作为备件。
坚固耐用的设计：作为工业级组件，它能够在严苛的工厂和过程环境中可靠运行。
原产国：通常产自瑞典。

Key Product Details and Functions
Analog Input Module:Its primary function is to convert analog signals from field devices into digital data that the controller can process.These analog signals typically come from sensors measuring physical quantities like temperature,pressure,flow,level,etc.
Channels:The DSAI130A features 16 analog input channels.This allows it to monitor a significant number of analog sensors simultaneously within an industrial process.
Input Signal Types:It supports common industrial analog input ranges,including:
+/-10V(voltage signals)
+/-20mA(current signals)
This versatility makes it compatible with a wide array of industrial sensors and transmitters.
High Accuracy:The module is known for its high accuracy,typically 0.025%.This precision is critical for applications where accurate measurement and control of process variables are paramount.
Differential Input:The”Differential Input”feature means it measures the voltage difference between two input terminals for each channel,which helps to reduce common-mode noise and improve signal integrity in noisy industrial environments.
Compatibility:The DSAI130A(3BSE018292R1)is a revitalized version of the older DSAI 130(57120001-P).It’s designed to be used with standard process controllers like ABB’s AC410,AC450,and AC460,especially when the common mode voltage(CMV)is less than or equal to 50V.For older safety controllers(MasterPiece 2×0)or when CMV is greater than 50V,the older DSAI 130 might be specifically required as a spare part.
Robust Design:As an industrial-grade component,it’s built to operate reliably in challenging factory and process environments.
Country of Origin:Often manufactured in Sweden.
