[原创] Maxim MAXM22510－1RS－485(422)全双工收发器模块解决方案

Maxim公司的MAXM22510/MAXM22511是隔离的RS-485/RS-422全双工收发器模块,在电缆边(RS-485/RS-422驱动器/接收器边)和UART边提供2500VRMS(60秒)电隔离,集成的DC/DC电源给模块的电缆边供电,不需要外接元件.MAXM22510通信速率高达500kpbs,MAXM22511通信速率高达25Mbps,可用于工业4.0如工业自动化,可编逻辑控制器(PLC),HVAC,功率表和建筑物自动化.本文介绍了MAXM22510/1主要优势和特性,功能框图,应用电路,以及评估板MAXM22511 EVK主要特性,电路图,材料清单和PCB设计图.

The MAXM22510 and MAXM22511 isolated RS-485/ RS-422, full-duplex, transceiver modules provide 2500VRMS (60s) of galvanic isolation between the cable-side (RS-485/RS-422 driver/receiver side) and the UART-side of the device. An integrated DC-DC powers the cable-side of the module. No external components are required.

Isolation improves communication by breaking ground loops and reduces noise when there are large differences in ground potential between ports. These devices allow for robust communication up to 500kpbs (MAXM22510) and 25Mbps (MAXM22511).

The MAXM22510/MAXM22511 operate from a single 3.3V supply on the UART-side. An integrated DC-DC converter generates the 3.3V operating voltage for the cable-side of the module.
