AI890 模拟量输入模块有 8 个通道。该模块的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。
每个通道可以是电流输入或电源,并监控一个两线制过程变送器。电流输入用于外部供电的变送器。电流输入的输入压降典型值为3 V(包括PTC)。每个通道的变送器电源能够提供至少15 V/20 mA的环路电流,为Ex认证的过程变送器供电,在过载条件下限制为23 mA。所有 8 个通道都与 ModuleBus 和电源隔离在一组中。输入级的功率从电源连接上的 24 V 转换而来。
TU890 和 TU891 紧凑型 MTU 可与此模块配合使用,无需额外端子即可将两线连接到过程设备。TU890 用于防爆应用,TU 891 用于非防爆应用。

The AI890 analog input 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 be a current input or a power supply and monitor a two-wire process transmitter. Current input A transmitter for external power supply. The input voltage drop for current inputs is typically 3 V (including PTC). Transmitter power supplies in each channel are capable of delivering a minimum of 15 V/20 mA loop current to power Ex certified process transmitters, limited to 23 mA under overload conditions. All 8 channels are isolated from the ModuleBus and power supply in a group. The power of the input stage is converted from 24 V on the power supply connection.
The TU890 and TU891 compact MTU can be used with this module to connect two wires to process equipment without additional terminals. The TU890 is for explosion-proof applications and the TU 891 is for non-explosion-proof applications.
Characteristics and advantages
• 8 channels for 0... 20 mA or 4... 20 mA, single-ended unipolar input.
• 1 group of 8 channels isolated from the ground.
• Power and monitor explosion-proof certified two-wire transmitters.
• Non-energy storage analog input for external power supply.
