Application The signal isolator SINEAX TI 816 (Fig. 1) serves to electrically insulate an analog DC signal in the range 0...20 mA which depending on version is then converted to a current or voltage signal (0…20 mA or 0…10 V). It operates passively and does not require a separate power supply, but derives the little auxiliary energy it needs from the DC signal. Its narrow casing is designed for mounting on different types of standard rails. A number of signal isolators can be mounted immediately next to each other and where there are many DC signals to be isolated can form a compact isolator block.

应用信号隔离器SINEAX TI 816（图1）用于对0…20mA范围内的模拟直流信号进行电绝缘，然后将其转换为电流或电压信号（0…20mA或0…10V）。它被动工作，不需要单独的电源，但从直流信号中获得所需的少量辅助能量。它的窄外壳设计用于安装在不同类型的标准导轨上。许多信号隔离器可以安装在彼此相邻的中间位置，在有许多要隔离的直流信号的地方可以形成一个紧凑的隔离器块。

GMC-I Sineax TI 816 990722 功能和优点

● Electrically insulated analog DC signals 0…20 mA / Prevents the transfer of interference voltages and currents. Solves grounding problems in meshed signal networks ● Highly accurate / Performs its isolating function with negligible transmission error

● No power supply needed / Saves wiring costs and is easy to install in existing plants

● The device fulfils the protection requirements of the EMC guidelines (89/336/EWG) / The device bears the CE symbol for EMC. See “Table 2: Electromagnetic compatibility”

● Small and compact / Makes best use of the available space Fig. 1 Layout and mode of operation The DC signal isolator comprises a DC chopper Z, an isolating stage T, a rectifier G and an oscillator O. The chopper converts the DC input signal E to an AC signal which is transformed with electrical insulation, rectified, smoothed and appears at the output as a DC current signal A (Fig. 2, left). Versions with a DC output voltage signal A have a resistive burden through which the current flows (Fig. 2, right). The chopper is controlled by the oscillator which obtains its power from the DC signa

●电绝缘模拟直流信号0…20 mA，防止干扰电压和电流的传输。解决网状信号网络中的接地问题●高度准确

●无需电源DV节省布线成本，易于安装在现有工厂

●设备符合EMC指南（89/336/EEC）的保护要求/设备带有EMC的CE符号。见“表2：电磁兼容性”

●体积小、紧凑，充分利用可用空间图1布局和操作模式直流信号隔离器包括一个直流斩波器Z、一个隔离级T、一个整流器G和一个振荡器O。斩波器将直流输入信号E转换为交流信号，该信号经电绝缘转换、整流、平滑，并在输出端显示为直流电流信号a（图2，左）。具有直流输出电压信号a的版本具有电阻负载，电流流过该电阻负载（图2，右侧）。斩波器由振荡器控制，振荡器从直流信号中获得功率
