詳情介紹：

臺灣七泰多功能集合式電表CTEC-1700

CTEC-1700 是一只能在電力網路內量測、計算並顯示所有主要電力參數的多功能電表，所提供的數據，是經由三相電壓及三相電流輸入所得到的真有效值(TRMS)。

CTEC-1700依據EMC(電磁相容)及國際安規(guī)之要求所設計，並在ISO 9001品質管理下所生產的電表；他的特點是高精度、小尺寸、易安裝及低價位。利用其內裝的RS485/232介面及Modbus通信協定，能輕易和其他通信網路結合；此外，他還提供兩組繼電器告警接點輸出(DO)，及兩組告警接點輸入(DI)。

通信連結

RS-232C CONNECTION

The figure bellow illustrates the wiring requirements for connecting the CT1700 using RS-232C communications. This can include a local direct connecting the CT1700 using RS-232C communications. This can include a local direct connection to a computer or other device. The RS-232C standard allows only a single point-to-point communication connection. Using this method, only one RS-232C equipped device may be connected to the serial port of the computer, or other device. The cable used between the computers is a standard RS-232C communication cable with a maximum length of 50 feet (15.2m).

RS-485 CONNECTION

RS-485 communication allows multiple devices to be connected on the same bus. Up to 30 devices can be connected on a single RS-485 bus, which consists of a shield twisted pair cable. The overall length of the RS-485 cable connecting all devices cannot exceed 4000 feet (1219m).
