AI895 模拟量输入模块可以直接连接 2 线制变送器，通过特定连接，它还可以连接 4 线制变送器，而不会失去 HART 功能。AI895 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。每个通道都可以为两线制过程变送器和HART通信供电和监控。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。

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，TU891 用于非防爆应用。

dimension

The AI895 analog input module can be connected directly to a 2-wire transmitter, and with a specific connection, it can also be connected to a 4-wire transmitter without losing HART function. The AI895 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 power and monitor two-wire process transmitters and HART communications. 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.

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 TU891 is for non-explosion-proof applications.

Characteristics and advantages

• 8 channels for 4... 20 mA, single-ended single-pole input.

• HART communication.

• 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.
