Multi-Circuit Monitoring Detector

XWS-M
The XWS-M series products are intelligent power safety monitoring detectors that integrate power consumption data such as residual current, current, voltage, temperature, and power. They also have functions such as relay control output, system clock display, and remote linkage to monitor and upload comprehensive power consumption information.
NB, 4G, 485, LAN and other communication methods can be selected to realize IoT remote monitoring. The electrical safety system IoT monitoring platform can directly manage all monitoring module data connected to the platform, and provide real-time alarm, SMS alarm, historical alarm record query and other functions. The information of the module can be queried in real time through the monitoring platform, including the current alarm value, alarm setting value, actual value of each output number, number of network disconnections and other information.

Features Technical Indicators Overall Dimension

1. 4 residual currents, 16 currents, 3 voltages, and 16 temperatures.
2. Alarm functions such as residual current, overcurrent, overtemperature, phase loss, overvoltage, undervoltage, power failure, arc fault, or remote linkage.
Note: Only one of the arc fault and remote linkage functions can be selected, and the default is the arc fault function.
3. Optional communication methods: NB, 4G wireless communication, 485, LAN wired communication.
4. With sound and light alarm function, timely detection of safety hazards.
5. Normally open to normally closed output function during alarm.
6. Real-time query of module information can be achieved through the Internet of Things monitoring platform to realize remote operation.
7. When an alarm occurs, the user can be notified by SMS to handle the alarm information in time.
8. Provide LCD display and local data query.

Technical Parameters	Alarm setting value	Display Range	Setting the step size	Accuracy level
Residual current	20mA～1000mA	20mA～1500mA	1mA	±3%
Current	1A～Transformer ampere	1%A of the transformer ampere to 1.2 times the transformer ampere	1A	±3%
temperature	45℃～140℃	0℃～140℃	1℃	±2℃
Voltage	AC230V～AC400V(overvoltage) AC0V～AC210V(undervoltage)	AC50V～AC400V	1V	±3%

Working voltage: AC198V～242V/50Hz Standby power consumption: <2W.
Alarm delay: Setting value: 1s～60s.
If the value is less than the display range, it will display “<MIN”; if the value is greater than the display range, it will display “>MAX”; if the circuit is closed, it will display “OFF”.
Environmental conditions: (1) Ambient temperature: -10℃～＋45℃ (2) Relative humidity: ≤90%, no condensation.
