SM942
直流电源冗余分配模块
概述
SM942 SM 系 列 控 制 系 统 硬 件 产 品 中 的
24V/48VDC 直流电源冗余分配模块,实现 4 24VDC
输入经冗余分配到 8 24VDC 并接输出,输入电压给
出供电指示;同时实现两路 48VDC 并接输入分配到 18
48VDC 的输出,输出各路给出短路指示。
SM942 采用模块化设计,螺钉平面固定。图 1

工作原理
1 SM942 模块外观图
24VDC 系统电源分为 2 组,每组 2 24VDC 输入,4 24VDC 输出。其中,每路 24VDC 输入经
肖特基二极管冗余后并接输出 4 24VDC24VDC 系统输入电源经状态监测输出电路可实现远端电源
状态诊断与报警。状态监测电路的输出为无源触点输出,因此兼顾查询电源为 DC 24V DC 48V
DI 采集模块。24/48VDC 查询电源将两路 24/48VDC 输入分别经肖特基二极管冗余后并接输出 18
24/48VDC,其中 16 路用于现场查询电源输出,另外 2 路用于现场查询电源的级联扩展。
SM942 模块的硬件工作原理框图如图 2 所示。
