DMB96500 초슬림형 범용 AI / DI 모드버스 RS485 통신 모듈 / 트랜스미터 전원공급 Modbus Universal AI / DI Module DMB 96500

모드버스(Modbus) 범용 아날로그/디지털 입력 모듈은 광범위한 산업용 센서와 함께 사용하도록 되어 있습니다. 모든 파라미터는 Modbus RTU 인터페이스를 통해 설정할 수 있습니다. 일반적으로 가장 많이 쓰이는 입력신호 및 모드버스 출력 모드 조합에 대해서는 DIP 스위치를 통해 설정할 수 있습니다.

변환 결과는 Modbus RTU (RS485) 인터페이스를 통해 읽을 수 있습니다.

2-way 절연은 처리회로와 보조전원 회로에서 센서회로의 신뢰성 있는 분리를 보장합니다. 보조전원 및 Modbus RTU는 연결단자 또는 인레일버스 커넥터(In-Rail-Bus Connector)를 통해 연결할 수 있습니다 (액세서리 참조).

The Modbus Universal AI/DI Module is intended to be used with a wide range of industrial sensors. All parameter can be set via Modbus RTU Interface. A subset of the most common settings is available via DIP switches.

The conversion result can be read over the Modbus RTU (RS485) interface.

The 2-way isolation guarantees reliable decoupling of the sensor circuit from the Processing circuit and the auxiliary power circuit. Auxiliary power and Modbus RTU can be connected via the connection terminals or via the In-Rail-Bus connector (see accessories).
