The DRA-ACT-4I AND DRA-ACT-4V Series are isolated 4-wire 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-4I Series of ac current input models includes models for 0-1 Aac and 0-5 Aac inputs with a 4-20 mA output. The DRA-ACT-4V Series of ac voltage input models includes models for 0-150 Vac, 0-250 Vac and 0-400 Vac inputs again with a 4-20 mA output. Standard instrument power is 115 Vac, 50/60 Hz. Units can also be configured for optional 230 Vac, 50/60 Hz power. 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. Zero and span trimmers accessible from the front panel of these units facilitate fine tuning.

DRA-ACT-4I和DRA-ACT-4V系列是隔離的4線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-4I系列交流電流輸入模型包括0-1 AAC和0-5 AAC輸入模型，輸出為4-20 mA。DRA-ACT-4V系列交流電壓輸入型號包括0-150 Vac、0-250 Vac和0-400 Vac輸入型號，以及4-20 mA輸出。標(biāo)準(zhǔn)儀器電源為115 Vac，50/60 Hz。裝置也可配置為可選230伏交流電、50/60赫茲電源。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。從這些裝置的前面板可以接近零點(diǎn)和量程微調(diào)器，便于微調(diào)。
