DRA-ACT-2V-2_DRA-ACT-2V-3交流电压/电流信号调节器OMEGA

DRA-ACT-2I和DRA-ACT-2V系列是隔离的2线回路供电的交流电流和交流电压输入DIN轨道安装信号调节器，将测量的输入转换成比例、线性和高度精确的4-20 mA输出电流。DRA-ACT-2I系列交流电流输入模型包括0至1 AAC和0至5 AAC输入模型，输出4至20 mA。DRA-ACT-2V系列交流电压输入型号包括0至150 VAC、0至250 VAC和0至400 VAC输入型号，以及4至20 mA输出。

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。完整的输入输出隔离，高的浪涌电流容量和高的输出信噪比，使这些信号调节剂高度免疫地回路信号和射频干扰。这些变送器还配有***个“测试”终端，通过测量内部10欧姆电阻器上的电压降，在不干扰4至20 mA工艺回路的情况下，方便监测输出电流。

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.
