DG3400 전압 측정 알람 릴레이 / 오픈콜렉터 스위치 출력 Voltage Measuring Contactor DG 3400

전압측정 신호경보기(Voltage Measuring Contactor) DG3400은 AC/DC 전압의 한계값을 모니터링하는데 사용됩니다.

높은 신뢰도와 방호분리(Protective Separation)는 결함이 없는 장치 작동에 기여하는 필수적인 특성입니다.

2개의 스위치 채널을 개별적으로 설정할 수 있습니다. 스위치 포인트(Switch Point)와 스위치 히스테리시스(Switch Hysteresis)는 경보기의 전면 패널에 위치한 자체 12회전 전위차계(12-turn Potentiometer)를 사용하여 각각 조절할 수 있습니다. 스위치 상태는 노란색 LED로 표시됩니다.

효과방향 및 작동모드는 DIP 스위치 설정을 통해 전환할 수 있습니다. 두 스위치 출력은 MIN 또는 MAX 알람으로 설정할 수 있습니다. 릴레이 접점은 a접점(상시개로, N/O, Normally Open) 또는 b접점(상시폐로, N/C, Normally Closed)으로 높은 전력부하를 절환합니다.

DG3400은 방호분리 및 24V AC/DC 전원공급 장치를 통해 모든 계측, 산업용 어플리케이션 및 빌딩 자동화에 보편적으로 적용할 수 있습니다.

The Voltage Measuring Contactor DG 3400 is used to monitor limit values of AC/DC voltages.

High reliability and Protective Separation are essential characteristics that contribute to fault-free equipment operation.

Two switch channels can be separately configured. The switch point and the switch hysteresis can each be adjusted by means of their own 12-turn potentiometer located on the unit’s front panel. The switch state is indicated by a yellow LED.

The direction of effect and the mode of operation can be switched by means of DIP switch settings. Both switch outputs can be set up as either MIN or MAX alarms. The relay contacts switch high power loads either as N.O. or N.C. contacts.

Protective Separation and the 24 V AC/DC power supply make the DG 3400 universally applicable for all measurement and industrial applications, as well as for building automation.
