DRA-ACT-2V-2_DRA-ACT-2V-3交流電壓/電流信號調(diào)節(jié)器OMEGA

DRA-ACT-2I和DRA-ACT-2V系列是隔離的2線回路供電的交流電流和交流電壓輸入DIN軌道安裝信號調(diào)節(jié)器，將測量的輸入轉(zhuǎn)換成比例、線性和高度精確的4-20 mA輸出電流。DRA-ACT-2I系列交流電流輸入模型包括0至1 AAC和0至5 AAC輸入模型，輸出4至20 mA。DRA-ACT-2V系列交流電壓輸入型號包括0至150 VAC、0至250 VAC和0至400 VAC輸入型號，以及4至20 mA輸出。

為了完全安全，內(nèi)部變壓器將信號調(diào)節(jié)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。完整的輸入輸出隔離，高的浪涌電流容量和高的輸出信噪比，使這些信號調(diào)節(jié)劑高度免疫地回路信號和射頻干擾。這些變送器還配有***個“測試”終端，通過測量內(nèi)部10歐姆電阻器上的電壓降，在不干擾4至20 mA工藝回路的情況下，方便監(jiān)測輸出電流。

The DRA-ACT-2I AND DRA-ACT-2V Series are isolated 2-wire loop-powered ac current and ac voltage input DIN rail mount signal conditioners that convert the measured input into a proportional, linear and highly accurate 4-20 mA output current. The DRA-ACT-2I Series of ac current input models includes models for 0 to1 Aac and 0 to5 Aac inputs with 4 to20 mA output. The DRA-ACT-2V Series of ac voltage input models includes models for 0 to150 Vac, 0 to250 Vac and 0 to400 Vac inputs again with 4 to 20 mA output.

For complete safety, an internal transformer isolates the signal conditioner input from the output thus enabling these units to withstand large momentary inputs. Complete input to output isolation, high surge current capacity and high output signal-to-noise ratio make these signal conditioners highly immune to ground loop signals and RFI. These transmitters are also equipped with a “test” terminal which facilitates monitoring of the output current by measuring the voltage drop across an internal 10 Ohm resistor without disturbing the 4 to 20 mA process loop.
