Product Function

电位信号传送器是将阴极保护电源设备中采集到的参比电位、输出电流、输出电压、给定电位等参数通过A/D转换成RS485/以太网/标准工业信号4-20mA/RS232等接口，再通过信号电缆传送到中心控制室的设备，以便进行监测。

The potential signal transmitter converts the reference potential, output current, output voltage, given potential and other parameters collected in the cathodic protection power supply equipment into RS485/Ethernet/standard industrial signal 4-20mA/RS232 and other interfaces through A/D conversion, and then transmits them to the equipment in the central control room through signal cables for monitoring.
