SMS Alert 2.1

The RTU5023, RTU5026, RTU5027, RTU5028, and RTU5029 series are comprehensive monitoring devices designed for temperature, humidity, analog signals, power, and voltage. These units allow for customizable alarm thresholds based on specific application requirements, enabling users to set high and low limit alerts for temperature, humidity, analog signals, and power supply voltages. When a parameter reaches its preset threshold, the system triggers an alarm notification through message alerts and telephone notifications to designated users.

Users can obtain device status updates by calling the assigned authorization number; the system will automatically reject incoming calls after providing current status information via voice message. Additionally, real-time status inquiries can be made through SMS commands. The devices support scheduled daily reports and periodic status updates sent to the primary user, facilitating continuous monitoring.

The series is compatible with both Modbus RTU and Modbus TCP protocols, allowing integration with cloud platforms for remote and real-time monitoring over network connections.

These products are suitable for a variety of environments requiring environmental or electrical parameter monitoring, including classrooms, public spaces, hospitals, railway stations, food warehouses, offices, factories, libraries, and laboratories. They support multiple monitoring signals such as temperature, humidity, 4-20 mA analog input, 0-5V DC voltage, single-phase, and three-phase power measurements.
