串口至RS422/485隔离器[FT-KZ352]

浪涌保护的RS-232至RS-422/RS-485接口转换器，可以使一个RS-232终端设备与您的RS-422/485网络相连，它非常适用于PC机、终端设备、工业控制、数字仪表采集、多串口设备、单片机的串行接口等诸多领域。

性能指标：
　　★ 转换模式：将RS-232数据转换为RS422/485
　　★ 程控信号：无需RTS流控
　　★ 工作状态：LED状态指示灯
　　★ 信号：RS422:TXD+/-、RXD+/-
　　★ 信号：RS485:RX+(A)/RX-(B) 
　　★ 传输速率：300bps-115200bps 
　　★ 传输距离：1.2km 
　　★ 直流电源：DC9V 400mA
　　★ 隔离电压：持续隔离1000V;
　　★ 工作温度：0-75℃ 湿度≤90%(无冷凝)
　　★ 外形尺寸：850mm×50mm×25mm
　　★ 连接头：RS232接头为DB9；RS422/485为插入式端子

使用方法:
(1) DB9孔与RS-232设备用软线连接，DB9孔的2脚是发送，3脚是接收根据连接设备属性置DTE/DCE开关。(出厂时开关置在DCE端)
(2) RS-422/485侧为接线端子形式，包括TX+、TX-、RX+、RX-和电源输入 
(3) 电源应由RS-422/485侧统一供电，不能跟RS-232侧共地。
