DRA-ACT-SV-3_DRA-ACT-SV-4交流電壓/電流信號調節器OMEGA歐米茄

DRA-ACT-SI和DRA-ACT-SV系列是自供電的交流電流和交流電壓輸入的DIN軌道安裝信號調節器，使用測量的輸入產生精確的線性輸出電流。這些信號調節器具有良好的精度、線性度和穩定性，使它們獨一無二。DRA-ACT-SI系列交流電流輸入模型包括0-1 AAC和0-5 AAC輸入模型，可選擇0-1 mA或0-20 mA輸出。DRA-ACT-SV系列交流電壓輸入型號包括0-150 VAC和0-300 VAC輸入型號，可選擇0-1 mA或0-20 mA輸出。所有這些自供電模式的輸出電流總是從0 mA開始，因為這些裝置由測量信號供電。因此，當交流電流或電壓輸入為零時，輸出為零。為了完全安全，內部變壓器將信號調節器輸入與輸出隔離，從而使這些裝置能夠承受較大的瞬時輸入。輸入-輸出隔離提供高輸出信噪比，使這些信號調節器高度免疫地面環路信號和射頻干擾。

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.
