信号类型 :单极性单端
AI815 模拟量输入模块有 8 个通道。这些模块可以配置为电压或电流输入。电流和电压信号不能在同一 I/O 模块上混合使用。电压和电流输入能够承受至少 11 V 直流的过压或欠压。
电压输入的输入电阻大于10 M欧姆,电流输入的输入电阻为250 Ω。该模块将外部HART兼容发射器电源分配给每个通道。这增加了一个简单的连接,将电源分配给 2 线或 3 线变送器。发射机功率受到监控和电流限制。如果使用外部电源为HART变送器供电,则电源必须与HART兼容。

Number of channels: 8
Signal type: Unipolar single-ended
The AI815 analog input module has 8 channels. These modules can be configured for voltage or current input. Current and voltage signals cannot be mixed on the same I/O module. Voltage and current inputs can withstand overvoltage or undervoltage of at least 11 V DC.
The input resistance of the voltage input is greater than 10 M ohms and the input resistance of the current input is 250 Ω. The module allocates external HART compatible transmitter power to each channel. This adds a simple connection that distributes power to a 2 - or 3-wire transmitter. Transmitter power is monitored and current limited. If an external power supply is used to power the HART transmitter, the power supply must be compatible with HART.
