1. Product Overview
Product Description
DTU2xx – a series of battery-powered data loggers
designed for remote metering and monitoring.
Device provides:
Automated data collection from meters with
pulse outputs, meters with serial RS-232 and
RS-485 ports and a wide range of sensors
(resistive, 4-20mA, 1-wire, etc);
Data storage in non-volatile memory;
Wireless data transmission to dispatching
server over GPRS or LTE NB-IoT network.
Data logger is made in an IP30 metal case and equipped with four configurable GPIOs, dual SIM
slots, serial RS-232 and RS-485 ports, and USB port for device configuring.
Devices are powered either from a 230V AC or from a 7-30V DC network (depending on model),
and also have a built-in replaceable 3500 mAh battery to provide backup autonomous operation of
the data logger in the event of external power failure. Battery service life ranges from 4 to 10 years
depending on the model (GPRS or NB-IoT) and its use.
The model range of DTU2xx is represented by the following base models:

Base model options:
-U – UDP protocol. A base software option for all DTU2xx NB-IoT models, which means that the device operates
over the UDP protocol. Otherwise, if there is no ‘-U’ marking, that means that the device operates over TCP protocol.
-C – a built-in 100-240 VAC power supply unit. A base hardware option for all DTU2xx data logger models. Other-
wise, if there is no ‘-C’ marking for these models, that means that the device has 7-30 VDC power supply.
