MEWOI9700 Power Failure/Leakage Current Remote Alarm Monitor, Suitable for remote online monitoring of power failure,  power supply restoration, leakage current, range:0.00mA~60.0A. Through the built-in GSM/GPRS module, send alarm SMS to the designated mobile phone number, it belongs to the industrial GSM/2G/3G/4G alarm monitoring instrument. It can also connect the temperature, humidity and human body infrared sensors and other sensors through the input expansion port, and control the remote relay and other equipment through the output expansion port. Widely applicable to all kinds of need power failure alarm, leakage monitoring alarm, remote control start and stop and other places.

The detector consists of host, alarm cell phone, current sensor, GSM/GPRS module, host computer software, power adapter, etc. The host monitors 1-channel current (LCD display current value), 1-channel external power  intact or break status (i.e. the intact or break status of the power supply), 3-channel extended input interface (DC 0 ~ 12V analog voltage), 3-channel extended output control interface (on/off: DC 12V/0V). With built-in large-capacity lithium battery  which has the function of charging management. When the external power supply is disconnected, the built-in lithium battery will continue to supply power to the host engine, comprehensively realizing the functions of remote monitoring, alarm and control .Current sensor is spilt type CT , very suitable for online installation, coil diameter for Φ 40 mm, users can according to the requirements to purchase different diameter current sensor.

This meter has two communication modes: GSM wireless communication mode, RS485 wired communication mode, in GSM wireless communication mode, between the host and alarm mobile phone adopt GSM short message communication, as long as there is GSM signal can communicate, not limited by distance, suitable for long-distance monitoring alarm. The user can also develop upper computer software separately according to the provided GSM SMS instruction protocol. RS485 wired communication which is adopted RS485 communication between the host and the computer. The host provides an RS485 interface and MODBUS protocol. Users can conduct secondary development according to the provided protocol. Wire communication suitable for short distance monitoring alarm.
