AI880A 高完整性模拟量输入模块专为单一和冗余配置而设计。该模块具有 8 个电流输入通道。输入电阻为 250 欧姆。
该模块将外部变送器电源分配到每个通道。这增加了一个简单的连接，将电源分配到 2 线或 3 线制变送器。变送器功率受到监控并限制电流。所有 8 个通道都与 ModuleBus 隔离在一个组中。模块的电源由ModuleBus上的24 V产生。
AI880A 符合 NAMUR 建议 NE43，并支持可配置的超量程和欠限。

The AI880A High integrity analog input module is designed for single and redundant configurations. The module has 8 current input channels. The input resistance is 250 ohms.
This module distributes external transmitter power to each channel. This adds a simple connection to distribute power to a 2 - or 3-wire transmitter. Transmitter power is monitored and current is limited. All eight channels are isolated from the ModuleBus in a group. The power supply for the module is generated by 24 V on the ModuleBus.
The AI880A complies with NAMUR recommendation NE43 and supports configurable overranges and underlimits.
