DTU terminal / DTU data acquisition terminal SM5100

Overview:

          SM5100ZigBeeDTU is a simplified version of RTU. It can convert digital sensor data using ZigBee communication into ModBusRTU/TCP standard interface protocol is convenient for third-party users to integrate the system.

This DTU encapsulates the standard communication protocol used in the construction of domestic digital oil fields:

1. Downlink data: communicate with wireless digital sensors at the well site, and can be compatible with PetroChina's "A11" and Sinopec's "Four Chemicals" standard protocols; other third-party wireless instrument protocols can also be customized:

2. Uplink data: communicate with the station control center server or PLC, inverter and other control equipment, you can choose RS485, RS232, Ethernet and other interface forms to realize ModBusCommunication transmission of standard protocols such as RTU/TCP and IEC104.

This DTU can be equipped with wireless digital sensors and is widely used in industrial Internet of Things measurement and control systems: it has been widely used and well received in oil well production data collection, environmental protection, agriculture, forestry, water affairs, coal mining, petrochemical and other fields.
