DRA-ACT-SV-3_DRA-ACT-SV-4交流电压/电流信号调节器OMEGA欧米茄

DRA-ACT-SI和DRA-ACT-SV系列是自供电的交流电流和交流电压输入的DIN轨道安装信号调节器，使用测量的输入产生精确的线性输出电流。这些信号调节器具有良好的精度、线性度和稳定性，使它们独一无二。DRA-ACT-SI系列交流电流输入模型包括0-1 AAC和0-5 AAC输入模型，可选择0-1 mA或0-20 mA输出。DRA-ACT-SV系列交流电压输入型号包括0-150 VAC和0-300 VAC输入型号，可选择0-1 mA或0-20 mA输出。所有这些自供电模式的输出电流总是从0 mA开始，因为这些装置由测量信号供电。因此，当交流电流或电压输入为零时，输出为零。为了完全安全，内部变压器将信号调节器输入与输出隔离，从而使这些装置能够承受较大的瞬时输入。输入-输出隔离提供高输出信噪比，使这些信号调节器高度免疫地面环路信号和射频干扰。

The DRA-ACT-SI AND DRA- ACT-SV Series are self-powered ac current and ac voltage input DIN rail mount signal conditioners that use the measured input to produce an accurate and linear output current. These signal conditioners have excellent accuracy, linearity and stability which make them unique. The DRA-ACT-SI Series of ac current input models includes models for 0-1 Aac and 0-5 Aac inputs with a choice of either 0-1 mA or 0-20 mA output. The DRA-ACT-SV Series of ac voltage input models includes models for 0-150 Vac and 0-300 Vac inputs again with a choice of either 0-1 mA or 0-20 mA output. The output current from all of these self-powered models always starts at 0 mA since these units are powered from the measured signal. Therefore, when the ac current or voltage input is zero, the output is zero. For complete safety, an internal transformer isolates the signal conditioner input from the output thus enabling these units to withstand large momentary inputs. The input to output isolation provides high output signal-to-noise ratio which makes these signal conditioners highly immune to ground loop signals and RFI.
