DO890 3BSC690074R1 通道配置开路和短路检测

☆型号：DO890 3BSC690074R1 通道配置开路和短路检测

【产品详情】

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。

每个通道可将 40 mA 的标称电流驱动至 300 欧姆励磁负载，例如防爆认证电磁阀、报警发声器单元或指示灯。可以为每个通道配置开路和短路检测。所有四个通道在通道之间以及与 ModuleBus 和电源之间都是电气隔离的。输出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。

特点和优势

4 个通道，用于 11 V、40 mA 数字输出。

所有通道完全隔离。

驱动防爆认证电磁阀和报警发声器的电源。

每个通道的输出和故障状态指示器。

【英文介绍】

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 drive a nominal current of 40 mA up to 300 ohm excitation loads, such as explosion-proof certified solenoid valves, alarm sound unit or indicator lights. Open and short circuit detection can be configured for each channel. All four channels are electrically isolated between channels and from the ModuleBus and power supply. The power of the output stage is converted from 24 V on the power supply connection.

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.

Characteristics and advantages

4 channels for 11 V, 40 mA digital output.

All channels are completely isolated.

Power supply to drive explosion-proof certified solenoid valves and alarm sounders.

Output and fault status indicators for each channel.
