Cost-effective DIN-Rail 4G LTE Cat 1 Modem
Support European LTE
mainstream frequency bands
Compact size
and easy integration
High speed rate
and low latency
Easy installation of its
DIN-Rail mounting
DIN-Rail series launched by Jinan USR IOT Technology Limited, include
Serial to Ethernet converters, 4G LTE Cat 1 modems and 4G industrial
routers. Their built-in 35 mm DIN rail seat apply to all DIN-Rail installation
scenarios. USR-DR502-E is shown as following
PC+ABS materials, compact, low cost; flame retardant grade V0,
ensuring the safe use of the product
Convenient cabling for installation, less space usage,
and ease of use with other products
Support the RS485 serial port, and easily deliver the data transparently
between RS485 and 4G LTE Cat 1 network in bi-direction
Support the four sockets connection, TCP client and user datagram protocol (UDP).
Support the customized heartbeat package and registration package functions.
Support the submission of serial data to the designated server
in HTTP (GET/POST) mode
Support the parameter configuration of serial, network and SMS commands,
and provide the configuration tool for the PC.
With the remote management platform, it can realize the automatic
firmware upgrade The upgrade package of difference algorithm is small,
and the upgrade traffic and time are saved
Level-3 ESD protection, level-3 surge protection, and built-in hardware watchdog
Data Collection of Distribution Boxes
By virtue of its small size and DIN-Rail installation, USR-DR502 can be installed in
a low voltage distribution box to save space. With extremely fast response speed,
4G DTU device can timely send data to the control platform.

Remote intelligent meter readingMay 05,2022
In nowadays, the large number of various meters are dispersed in different locations, some of which are remote and difficult to access, a remote meter reading system is urgently needed to relieve staff of utilities from heavy but inefficient tasks.Traditionally, the utilities companies used to hire thousands of meter readers to go around to read the meter, and always spend much money on traffic and labor.
