USR-K7 Low Cost TTL UART to Ethernet Serial Converter 10/100Mbps Modbus Gateway Module with RJ45 Port, 10PCS Pack

The USR-K7 is a budget-friendly TTL UART to Ethernet serial module fitted with standard RJ45 port and 10/100Mbps adaptive network speed. It acts as a lightweight Modbus gateway to realize seamless bidirectional conversion between Modbus RTU serial data and Modbus TCP industrial Ethernet signals, which connects TTL PLCs, industrial meters, sensors and serial controllers to local area networks conveniently. This serial-to-Ethernet module supports multiple flexible working modes to satisfy different remote data transmission demands. All network and serial parameters can be quickly set via web page or serial AT commands, with DHCP auto IP acquisition to simplify on-site wiring and debugging.

Featuring small size and low power consumption, the module delivers consistent long-distance data transfer. This 10-units bulk pack cuts procurement costs for system integrators and engineering projects. It is widely adopted in factory automation, remote data collection, intelligent monitoring and various IoT serial communication systems, and supports remote firmware upgrade to maintain stable long-term operation.
