模拟标准信号
AD-STVEX 710 GVD
产品介绍
电源隔离放大器用于为安装在危险区域的变送器提供本质安全电源。电源隔离放大器本身作为相关电气设备安装在非危险区域（即安全区域）。信号被电隔离并传输到非危险区域。无源输入还允许来自危险区域的有源信号。有源电流输出、电流吸收输出和电压输出便于适应后续信号输入。该设备可在 24 V DC 或 230 V AC 下运行。

接触放大器
AD-KVEX 100/200 GVD
产品介绍
接触放大器（开关放大器）优选地用于保护弱传感器接触或放大二进制传感器信号。 AD-KVEX 100/200 GVD 提供在触点输出处放大的逻辑输入信号。典型的输入信号是簧片触点、符合 Namur Namur (DIN EN 60947-5-6) 的信号传感器或电阻变化。在输出端，提供重载和无源触点。对于每个导管，逻辑切换方向以及线路故障识别是可单独切换的。 AD-KVEX 100/200 GVDO 版本具有无磨损半导体输出，也通过光学隔离进行电流隔离。该器件包含电子宽范围电源，可以在宽电源电压范围内运行。
