IC690RFH008 GE 多模反射式内存集线器 24 伏直流

IC690RFH008 GE 多模反射式内存集线器 24 伏直流

产品功能

输入电压范围为18至30V直流电，24V时输入电流为6mAo输入分为两个独立隔离的组，每组有八个通道和一个电压监控输入。

每个输入通道由限流元件、EMC保护元件、输入状态指示LED和光隔离栅组成。

如果电压消失，过程电压监控输入会发出通道错误信号。错误信号可以通过模块总线读取。对于本地节点，反射内存板显示为共享内存。任何级别的软件（包括应用程序本身)都可以将数据写入内存或从内存中读取数据。写入一个节点的反射内存的数据由网络硬件传输到所有其他节点，并放置在这些节点的反射内存板上的相同地址中。

这种数据传输无需任何节点上的处理器参与即可完成。通过该系统，网络上的所有节点都具有可立即访问的共享数据的本地副本。

特点和优点:

16个通道,用于24V直流输入,带电流吸收两组隔离,每组8个，带电压监控

Product function

The input voltage range is 18 to 30V DC, and the input current is 6mAo at 24V. The input is divided into two independently isolated groups, each with eight channels and a voltage monitoring input.

Each input channel consists of a current limiting element, an EMC protection element, an input status indicator LED, and an optical isolation gate.

If the voltage disappears, the process voltage monitoring input emits a channel error signal. The error signal can be read through the module bus. For local nodes, the reflected memory board appears as shared memory. Any level of software, including the application itself, can write data to or read from memory. Data written to the reflected memory of one node is transmitted by the network hardware to all other nodes and placed at the same address on the reflected memory boards of those nodes.

This data transfer can be done without the involvement of processors on any node. With this system, all nodes on the network have a local copy of the shared data that is instantly accessible.

Features and advantages:

16 channels for 24V DC input, with current absorption two groups of isolation, each group of 8, with voltage monitoring
