☆型号：AO890 3BSC690072R1 模拟量输出模块 有 8 个通道

【产品详情】

AO890 模拟量输出模块有 8 个通道。该模块在每个通道上都包含本质安全保护组件，用于连接到危险区域的工艺设备，而无需额外的外部设备。

每个通道可向现场负载（如防爆认证的电流-压力转换器）驱动高达 20 mA 的环路电流，在过载条件下限制为 22 mA。

TU890 和 TU891 紧凑型 MTU 可与该模块配合使用，无需额外的端子即可将两根线连接到过程设备。TU890 用于防爆应用，TU891 用于非防爆应用。

特点和优势

•8 通道 0...20 mA、4...20 mA 输出。

•1 组 8 通道与地面隔离。

•驱动防爆认证的 I/P 执行器的电源。

AO890和3BSC690072R1都是模拟输出模块，但它们的应用和特点略有不同。

AO890是一款模拟输出模块，用于将数字信号转换为模拟信号，以便控制各种模拟设备。该模块具有高精度、低噪声、低失真等特点，可以广泛应用于音频处理、信号控制等领域。

3BSC690072R1是一款冗余应用模拟输出模块，适用于需要高可靠性和可用性的应用。该模块具有双重输出功能，可以同时输出两个模拟信号，并且具有自动切换功能，可以在主输出故障时自动切换到备用输出。这种冗余设计可以提高系统的可靠性和稳定性，减少停机时间和维护成本。

总之，AO890和3BSC690072R1模拟输出模块都具有高精度和高可靠性的特点，但3BSC690072R1的冗余设计使其更适合需要高可用性的应用。如需更多信息，建议访问制造商官网或咨询相关业内人士。

【英文介绍】

The AO890 analog output module has 8 channels. The module contains intrinsically safe protection components on each channel for connecting process equipment to hazardous areas without the need for additional external equipment.

Each channel can drive loop currents up to 20 mA to field loads, such as explosion-proof certified current-pressure converters, limited to 22 mA under overload conditions.

The TU890 and TU891 compact Mtus can be used with this module to connect two wires to process equipment without the need for additional terminals. The TU890 is for explosion-proof applications and the TU891 is for non-explosion-proof applications.

Characteristics and advantages

•8 channel 0... 20 mA, 4... 20 mA output.

•1 group of 8 channels isolated from the ground.

• Power supply to drive explosion-proof certified I/P actuators.

The AO890 and 3BSC690072R1 are both analog output modules, but their applications and characteristics are slightly different.

The AO890 is an analog output module for converting digital signals to analog signals in order to control various analog devices. The module has the characteristics of high precision, low noise and low distortion, and can be widely used in the fields of audio processing and signal control.

The 3BSC690072R1 is a redundant application analog output module for applications that require high reliability and availability. The module has dual output function, which can output two analog signals at the same time, and has automatic switching function, which can automatically switch to the standby output when the main output fails. This redundant design improves system reliability and stability, reducing downtime and maintenance costs.

In summary, both the AO890 and 3BSC690072R1 analog output modules feature high accuracy and reliability, but the 3BSC690072R1's redundant design makes it more suitable for applications requiring high availability. For more information, it is recommended to visit the manufacturer's website or consult relevant industry insiders.
