Product Introduction:
SCJ-DATA21 (IP68) low-power measurement and control terminal is an integrated 4G DTU, lithium battery and low-power IoT data acquisition terminal; built-in 12v 22.4AH or 44.8AH lithium battery (larger capacity can be customized), protection level reaches IP68, equipped with low-power Bluetooth to support mobile phone on-site configuration, support flow or water level or other sensor data acquisition, built-in 16MB memory, can meet more than 1 year of data storage needs, while supporting remote configuration upgrade function, reducing the difficulty of customer installation and use.
Features:
Internally integrated 4G DTU, communication can be achieved without the need for an external DTU:
The protection level reaches IP68 and can work underground for a long time:
Built in lithium battery, integrated design, easy installation:
The low standby power consumption and optimized acquisition and transmission algorithm greatly increase the battery working time:
Built in low-power Bluetooth, convenient for on-site non-contact debugging and setting parameters through mobile phones, and querying data:
Supports USB interface, which can be used to connect with computers for configuration, data query, historical data export and other functions;
Support external charging interface, optional external solar or mains power supply:
Supports 1 485 or 2 4-20mA interfaces:
Support 1-channel pulse/switch signal acquisition (default not enabled)!
Built in external independent watchdog ensures stable and reliable operation of the device;
Support local/remote configuration upgrade, historical data resend function:
Extremely low standby power consumption (<30uA, requiring only 0.26AH battery for 1 year of standby):
Support 3 central stations to send data simultaneously (at the same time, 3 central stations can send data simultaneously):
Support communication between three central stations using different communication protocols:
Support rapid customization of communication protocols and sensor acquisition protocols;
Can be directly matched with various water quality, flow rate, or water level gauges of the company for underground use:
