Product overview
ATS130G series residual current temperature measuring device is a new type of anti-risk equipment which integrates the detection, warning, alarm, communication and other functions of residual current and temperature, and has intelligent analysis ability. When an electrical accident occurs in the power supply equipment, the monitor can issue an alarm to remind the staff to check the fault in time, eliminate possible electrical hazards, and prevent accidents.
The residual current temperature measuring device is suitable for residential buildings, hospitals, libraries, computer rooms, market malls, public cultural and entertainment places, restaurants, hotels, collective dormitories, schools, cultural relics protection units, factories, workshops, general warehouses, and other regional user safety fire protection, but not suitable for flammable and explosive and highly corrosive environment. The instrument provides RS485 communication interface and applies Modbus communication protocol, which is convenient for computer programming to set up or read data.
