Martens 放大器 TV125M / ST125M 隔离放大器 Martens of the GHM GROUP
TV125M / ST125M系列的隔离放大器适用于电位分离或转换标准信号。输入和输出的通用设计以及具有宽范围电源的内部电源使得*具有一种类型的设备的广泛应用成为可能。
或者，电源可以通过安装导轨总线连接器进行。可插拔的端子排允许简单且省时的布线。
输入和输出信号的配置由前面板DIP开关以非常简单和快速的方式完成。
由于微处理器的设计，可以解释测量范围的下冲或超出，并通过前面板上的双色状态LED报告。如果出现错误，则将输出设置为定义的初始值或结束值。
测量范围的初始值和结束值可通过两个前置式修剪器进行调整。
ST125的设备版本还为外部2线，3线和4线传感器提供发射器电源。
