Product Description

The USR-DR504-G module, part of the DR500 series DTU, serves as a USR cellular IoT gateway designed for industrial connectivity. It features 4 digital inputs, 4 digital outputs, and supports direct integration with up to 32 external modules via RS485. Equipped with 4G LTE, Ethernet, and Wi-Fi interfaces, it ensures robust communication across diverse networks. Operating within 9-36V DC and temperatures from -40°C to 75°C, it excels in harsh environments for applications like industrial automation, energy monitoring, and smart agriculture. The module lacks a built-in screen or battery, relying on external power. Key advantages include high reliability, remote configurability, and broad protocol support (MQTT, Modbus), while its dependency on stable cellular coverage may limit use in low-signal areas.
