USR IoT (a subsidiary of Shandong PUSR IOT), long-term partner of SOS electronic and manufacturer, which takes pride in its manufacturing capabilities, quality, and reliability of its products and services, recently introduced a completely new generation of two I/O modules for data collection and control to the market.
I/O edge gateway USR-M100 is an intelligent gateway that incorporates edge computing power. It can collect Modbus data within milliseconds and immediately upload them to common MQTT platforms like AWS, ThingsBoard, or PUSR Cloud, enabling remote and real-time data monitoring. It also provides high flexibility and expandability through additional modules. The local I/O state processing feature allows for automatic control even in offline mode.
“Compared to the previous generation, the I/O edge gateway USR-M100 introduces a significant innovation, which is the PLC function. It is a user-friendly solution for data collection and control in the industry, with an excellent balance of price and performance,” said Pavel Kováč, a product specialist at SOS electronic.
USR-M100 – converter and PLC in one solution
The I/O edge gateway USR-M100 features a unique mechanical design that reduces the time required for installation and operation, simplifying deployment and maintenance. In addition, it supports the Modbus RTU Master protocol for data acquisition from serial meters and also supports OT/IT protocol conversion.
Thanks to its ability to convert between multiple protocols, the USR-M100 can convert collected I/O and serial data into protocols suitable for various higher-level software. For example, cloud services via MQTT, SCADA via Modbus TCP, web servers via HTTP, and more.
The 2-in-1 design reduces system complexity, the amount of space required in network topology, and overall installation time. Users can also connect their older devices to the Ethernet network, extending the lifespan of their devices because they can continue to use the original device protocols.
“A unique feature of this device is its ability to work as a PLC (programmable logic controller), meaning it can perform locally configured tasks based on input status, such as controlling pumps, fans, air conditioning, and other devices,” says Pavel Kováč, a product specialist from SOS electronic.
