RS485rep-2 two-channel RS485 isolated relay/converter product data sheet. This product has 2 electrically isolated RS485 bus interfaces, one of which can be switched to RS232 interface. It can realize RS485 signal amplification or mutual conversion with RS232 signal. Product features include 2 isolated RS485 interfaces, the second RS485 channel can be switched to RS232 channel, each RS485 channel can carry at least 32 standard nodes or 128 enhanced nodes, isolation voltage 2500V DC, adaptive baud rate 300~115200bps, communication port using uniform baud rate, forwarding delay<1us, input floating protection, ESD protection, with shielded wire ground interface, working voltage: 9~24VAC/DC, working temperature: -25℃～+85℃.
The RS485rep-2 provides two isolated RS485 channels, each capable of 2300 VDC isolation and ESD protection up to 2500 V. One channel can be switched to RS232 mode, allowing flexible integration with PLCs, industrial PCs or other control equipment. The device operates from a 9‑24 V AC/DC supply and supports baud rates from 300 to 115200 bps.
Typical applications include Modbus networks, factory automation, and any system requiring robust electrical isolation between field devices and control units. The datasheet details hardware architecture, connector pin‑outs, LED status indicators, and safety specifications. This manual is written in Chinese.
