GE模块单元IC693PBS201

4-20mA和电工标准有关,4-20mA信号制是国际电工委员会(IEC)过程控制系统用模拟信号标准。我国从DDZ-Ⅲ型电动仪表开始采用这一国际标准信号制，仪表传输信号采用4-20mA,联络信号采用1-5VDC,即采用电流传输、电压接收的信号系统。

因为信号起点电流为4mA,为变送器提供了静态工作电流，同时仪表电气零点为4mA，不与机械零点重合，这种活零点有利于识别断电和断线等故障。

1、两线制电流/电压输出传感器(无供电电源，由负载提供16—24V配电，输出4-20mA/0-5V)。

1.1两线制无源4-20mA输入型传感器，经电流隔离配电器配电后与PLC连接。如图1所示，称重、测距传感器正端接16—24VDC,负端输出4-20mA电流。
