루프 전원 신호절연기(Input Loop-Powered Isolator) DH18은
0(4) ~ 20mA 표준신호의 전기적 절연에 사용됩니다.
DH18은
측정신호를 높은 정확도로 출력으로 전송하고 간섭전압(Interference
Voltage)이 하위로 이어지는 것을 방지하고 효과적으로
간섭을 억제합니다. 하나 또는 두 개의 채널에 대해 폭
11.2mm의 슬림형 하우징은 DIN 레일에 상당한 공간을 확보합니다.
지능형
설계와 그에 따른 고도로 집적된 부품의 필수적인 방지기능은
측정신호의 왜곡 없이 매우 긴 수명과 신뢰성을 제공합니다.
허용되지
않는 고전압에 대한 유지보수 인원과 하위 설비를 보호하기
위해 DH18은 EN61140에 따라 방호분리(Protective Separation)를
제공합니다.
DH18은
보조전원이 입력신호에서 왜곡되지 않고 얻어지므로 추가
전원공급이 필요하지 않습니다. 이는 설치비용을 절감할
뿐만 아니라 신뢰성을 높입니다.
The input loop-powered isolator DH 18 is used for the electrical isolation of 0(4) to 20 mA standard signals.
The DH 18 transfers the measuring signal to the output with a high degree of accuracy and avoids interference voltage carry-over and suppressing interferences effectively. The slim housing with 11.2 mm wide for one or two channels saves significant space on the DIN-rail. Intelligent design and their consequential avoidance of highly integrated components result in extremely long service lives and reliability without any falsification of the measurement signal. To protect both maintenance personnel as well as downstream equipment against impermissibly high voltages, the DH 18 offers Protective Separation in according to EN 61140. The DH 18 requires no additional power supply since the auxiliary power is obtained from the input signal without distorting it. This not only saves costs during installation, but also increases reliability.
