AEG MODICON AS-B875-001模拟输入模块 PDF资料
1.产 品 资 料 介 绍：
AS-B875-001 是老一代 AEG Modicon 800 系列里非常常用的 模拟量输入模块，专门给过程控制类现场点位做信号采集。它的定位就是：把现场真实的模拟量“干干净净地”送进主控制器，让 PLC 能做稳定的工艺调节。
1. 支持标准工业模拟信号
模块一般处理工业里最常见的几类模拟量，包括：
4–20 mA
0–10 V
1–5 V
部分版本也能接热电阻/低电平信号（依机架配置）
适合温度、压力、液位、阀位反馈、变送器类信号采集。
2. 通道隔离与抗干扰能力不错
这系列的模拟量卡做得还挺扎实，输入端隔离好、抗噪能力强，特别适合化工、电力、机械设备环境，长距离信号传输也不容易受干扰。
3. 多通道设计，节省机架资源
模块提供多路独立输入（常见是 8 通道），每一路都能单独读取，不会互相拖累，属于性价比很高的采集卡件。
4. 与 800 系列控制架构高度兼容
能直接挂在 AS-B8xx 机架上，与 800/984 系列控制器一起使用，属于那种装上就能跑、很少挑环境的老工程师常用模块。
5. 适合工艺类稳定控制
它采集速度不是追求“高速”的那种，而是强调：
稳定
无抖动
长期运行不漂移
特别适合温控、压力调节、阀门闭环系统等。
AEG MODICON AS-B875-001模拟输入模块 英文介绍
AS-B875-001 is a commonly used analog input module in the old generation AEG Modicon 800 series, specifically designed for signal acquisition at process control field points. Its positioning is to "clean up" the real analog signals on site and feed them into the main controller, allowing the PLC to perform stable process adjustments.
1. Support standard industrial analog signals
Modules generally handle the most common types of analog quantities in industry, including:
4–20 mA
0–10 V
1–5 V
Some versions can also connect to thermistor/low-level signals (depending on the rack configuration)
Suitable for temperature, pressure, liquid level, valve position feedback, and transmitter signal acquisition.
2. Good channel isolation and anti-interference ability
This series of analog cards is made quite solidly, with good input isolation and strong noise resistance, especially suitable for chemical, power, and mechanical equipment environments, and long-distance signal transmission is not easily affected by interference.
3. Multi channel design, saving rack resources
The module provides multiple independent inputs (usually 8 channels), each of which can be read separately without dragging each other, making it a cost-effective acquisition card.
4. Highly compatible with the 800 series control architecture
It can be directly mounted on the AS-B8xx rack and used together with the 800/984 series controllers, making it a commonly used module by experienced engineers who can run easily and rarely choose environments.
5. Suitable for process stability control
Its collection speed is not the kind that pursues "high speed", but emphasizes:
stable
No shaking
Long term operation without drifting
Especially suitable for temperature control, pressure regulation, valve closed-loop systems, etc.
