Industrial Grade NB-IoT RTU

CoAP/China Telecom NB-IoT Cloud/Industrial Grade Workmanship/Low Power Consumption/DI&DO

Power Failure Warning

In the event of a sudden power failure, the backup power supply will be activated and a power failure warning will be sent automatically, allowing users to know the status of the equipment in real time.

Independent R&D-Support script programming

• MDNR311 supports script programming. Users can customize scripts. There is no need for additional controllers and no need to rely on the platform to issue collection instructions. Directly connected meters can actively collect data from the meters and report them to the platform.
• The maximum collection volume can reach more than 50 instruments and meters, greatly reducing hardware costs.
• The reporting logic of DI (digital acquisition) can be customized in the script file.
• The control logic of DO (relay output) can be customized in the script file.

PSM Low Power Mode

The device runs with low power consumption and can’t receive downlink data from the data center. The RTU must actively upload data and enter the connection mode before the center can send data. After no data communication, MDNR311 RTU automatically enters PSM mode to maintain low power consumption standby.

SMS Push

The device can connect to the mobile phone through the Mind IoT cloud, and push data messages to the mobile phone in time. It supports sending to multiple mobile phones at the same time. Please contact online customers for consultation.

Heartbeat Packet Mode

By continuously sending data to connect to the server normally, the device is in an active state, ensuring the normal operation of device communication.

Software&Hardware Dual Watchdog

Adopting the hardware solution of “communication brand module + external independent 32-bit ARM core CPU”

• Well-designed external watchdog circuit, stable operation without crash, suitable for various field environment applications
• Integrated high-reliability composite watchdog, dual-dog soft/hard mode is mutual backup, DTU does not go down, to ensure the stability of data transmission

Support local/remote configuration upgrade

The user does not need to upgrade the firmware/software on the device site, and can remotely operate the device firmware/software upgrade through the monitoring center, sa manpower. The upgrade interface is fully graphical operation, unified with the local upgrade operation interface, and the device can operate normally during the remote upgrade process.
