DI890 3BSC690073R1 数字量输入模块有 8 个通道 本质安全保护组件

☆型号：DI890 3BSC690073R1 数字量输入模块有 8 个通道 本质安全保护组件

【产品详情】

DI890 数字量输入模块有 8 个通道。该模块在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。每个通道都与电源、接地和彼此电气隔离。本质安全型接近传感器或无电压触点可以通过任何通道供电和监控。

接近传感器应符合 NAMUR 标准，无需任何额外的外部组件即可检测线路故障。为了在使用无电压触点时检测线路故障，应将外部电阻器串联和并联，以使输入通道能够感测励磁电路的状态。所有 8 个通道均与 ModuleBus 和电源单独电气隔离。输入级的功率从电源连接上的 24 V 转换而来。三个 LED 指示模块状态故障（红色）、运行（绿色）和警告（黄色）。

TU890 和 TU891 紧凑型 MTU 可与该模块配合使用，无需额外的端子即可将两根线连接到过程设备。TU890 用于防爆应用，TU891 用于非防爆应用。

【英文介绍】

The DI890 digital 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 is electrically isolated from power, ground, and each other. Intrinsically safe proximity sensors or voltage-free contacts can be powered and monitored through any channel.

Proximity sensors should comply with NAMUR standards and detect line faults without any additional external components. In order to detect line faults when non-voltage contacts are used, external resistors should be connected in series and parallel so that the input channel can sense the state of the excitation circuit. All 8 channels are electrically isolated from the ModuleBus and power supply separately. The power of the input stage is converted from 24 V on the power supply connection. Three leds indicate module status Fault (red), operational (green), and warning (yellow).

The TU890 and TU891 compact Mtus can be used with this module to connect two wires to process equipment without the need for additional terminals. The TU890 is for explosion-proof applications and the TU891 is for non-explosion-proof applications.
