FB485-E              
RS-232转RS-485/422通用型双向转换器

RS232/RS485双向转换器

FB485-E串口转换器通过从RS-232端口取电来实现RS-232到RS-422/485转换,它将RS-232的TxD和 RxD信号转换为半双工的2线RS-485差分信号或全双工的4线RS-422/485信号。FB485-E RS232转RS485/422 转换器内建有15KV ESD浪涌保护功能,可防止输出信号的电流突波。FB485-E还提供了通过检测RS-232输出信号TxD状态来实现RS-485自动数据流向控制的功能。因此,客户不必自行控制RS-485数据的流向。

特点:

串口取电或外部供电;
串口可带电热插拨;
2/4线RS-485和RS-422方式可选
内置RS-485自动数据流向控制;
支持128节点轮询网络结构;
波特率50bps-115.2kbps;
通信距离0~3Km;
内置15KV ESD保护

FB485-CHG/CPG
RS-232转RS-485/422有源光电隔离转换器(工业RAIL机壳)

RS232转RS485 隔离转换器

FB485-CPG/CHG串口转换器实现RS-232到RS-485/422隔离转换,它将RS-232的TxD和 RxD信号转换为半双工的2线RS-485差分信号或全双工的4线RS-422差分信号。FB485-CHG 的RS-232侧由串口取电,FB485-CPG的RS-232侧由内嵌的DC-DC供电,RS-485侧由外部+5V或+9~+30VDC(Vs)电源供电,RS-232侧和RS-485侧通过光电隔离实现3000V的隔离保护。FB485-CPG内建有15KV ESD浪涌保护功能,可防止输出信号的电流突波。FB485-CPG RS232转RS485/422隔离转换器还提供了通过检测RS-232输出信号TxD状态来实现RS-485自动数据流向控制的功能。因此,客户不必自动控制RS-485数据的流向。正面有电源和数据收发指示灯,便于客户直观地了解FB485-CPG转换器的工作状态。

特点:

FB485-CHG:RS-232侧由串口取电;  FB485-CPG:RS-232侧由内嵌的DC-DC供电
RS-485/422侧+5V或+9~+30VDC(Vs)电源供电
3000V隔离保护
结构紧凑, 配一体化工业接线端子,标准孔式DB9,适合工业RAIL导轨安装
2线RS-485半双工通信,4线RS-422全双工通信
RS-485自动数据流向控制
自动侦测波特率
15KV ESD浪涌保护
