串口至RS422/485隔离器[FT-KZ352]

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。
