Din Rail RS485 Industrial cellular Modems

Din Rail RS485 Industrial cellular Modems


Din rail mounted RS485 industrial cellular modems with sim card slot USR-DR504-G with global bands can realize the data transmission between RS485 and 4G Network.

Din rail industrial modems USR-DR504-G are ideal for M2M and IoT applications—such as distribution automation, smart metering, water & wastewater, heating, street light monitoring and etc.

● Global Bands, Covering Global Regions
● DIN-Rail Mounted
● with sim card slot

Compact Industrial
Serial to Cellular Modem

Provide data two-way transparent transmission between
field serial devices and the central control server
Support 2 Socket connections, support TCP Client and UDP
Support custom heartbeat package and registration package

submit serial data to the designated server by HTTP (GET/POST) method

Modbus RTU/Modbus TCP protocol conversion for
industrial SCADA systems and field devices.

Registration Package plus Heartbeat Package

The registration packet is sent to the server to identify the device.
The heartbeat packet is used to judge the active state of the device when sent to the server,
and actively collect data when sent to the serial terminal.
The contents of registration package and heartbeat package,
heartbeat interval can be modified by AT command.

Parameter Configuration

Support AT command setup by serial port,network ,
SMS and provide configuration tool for PC(windows).

Remote FOTA Upgrade

With the remote management platform,it can realize the automatic
firmwareupgrade.The difference algorithm upgrade package is small,
saving upgrade traffic and time

Hardware Protection

Level-3 ESD protection, level-3 surge protection, and built-in hardware watchdog

DIN-Rail mounting

Convenient cabling for installation, less space usage,
and ease of use with other products.

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.
