基本信息

详细数据

AI830模拟输入模块有4个差分、双极电流/电压输入。每个通道可以是电压或电流输入。电流输入可以承受意外的正常模式30 V直流连接。为了保护电流输入电路免受危险输入电平的影响，即意外连接24 V电源，250W电流检测电阻的电阻额定值约为5瓦。这仅用于一次临时保护一个通道。

该模块将外部发射器电源分配到每个通道。这增加了一个简单的连接（带有扩展的MTU），以将电源分配到外部2线变送器。变送器电源端子没有电流限制。

The AI830 analog input module has four differential, bipolar current/voltage inputs. Each channel can be a voltage or current input. The current input can withstand unexpected normal mode 30 V DC connections. To protect the current input circuit from dangerous input levels, i.e. accidental connection to a 24 V supply, the resistance rating of the 250W current detection resistor is about 5 watts. This is only used to temporarily secure one channel at a time.

This module distributes external transmitter power to each channel. This adds a simple connection (with an extended MTU) to distribute power to an external 2-wire transmitter. Transmitter power terminal has no current limit.
