Product Introduction

ETCR8700 Power Failure/Electric Leakage Remote Monitor, also known as online power failure alarm, is used in industrial control sites that require unattended and remote online alarm to monitor power failure, restore power supply, and leakage. It is an industrial-grade 4G alarm monitor and can also be used as an anti-theft alarm.The monitor consists of a computer, a current sensor, a GPRS module, a host computer software, a power adapter, etc.Built-in GPRS module, users only need to set a few simple parameters through their own computer server, you can monitor whether the remote device is powered off, whether the power supply is restored, whether there is leakage and other alarm information at any time; you can also access temperature, humidity, human body infrared sensors and other sensors through the input expansion port; you can also control other equipment such as remote relays through the output expansion port.It is widely used in various places such as security, power equipment, banks, telecommunications, factories, railways, computer rooms, uninterruptible power supplies, biopharmaceuticals, warehouses, pharmacies, important machinery and equipment, 24-hour production lines, etc. That require power failure alarms, leakage monitoring alarms, remote control start and stop, etc.
ETCR8700 Power Failure/Electric Leakage Remote Monitor host monitors 1 channel of current (LCD display current value), 1 channel of external power supply on-off status (that is, the on-off status of the power supply), 3 channels of extended input interface (DC0～9V analog voltage), 3 channels of extended output control interface (on/off: DC12V/0V); provides 1 channel RS485 data interface and MODBUS protocol to facilitate secondary development; built-in large-capacity rechargeable lithium battery, with charging management function, when the external power supply is disconnected, the built-in lithium battery continues to power the host, fully realizing remote Monitoring, alarm, control and other functions.
The server can send setting instructions, alarm instructions, query instructions, factory reset instructions, etc. to the host through GPRS.For example: send relevant instructions to configure, power failure alarm, current value of power supply, leakage current alarm, leakage current alarm value setting; query current size, query power on or off status, query extended input interface voltage signal size, query extended output interface control on or off status, etc.
The current sensor is an open-close CT, which is very suitable for online installation. The aperture is φ40mm. Users can choose current sensors of different diameters according to their needs. The iron core uses special alloys and adopts magnetic shielding technology. It is almost unaffected by the external magnetic field, ensuring the high precision, high stability and high reliability of uninterrupted monitoring all year round.
1. Two communication methods: GPRS wireless communication method and RS485 wired communication method.
2. 3 extended input interfaces (DC0～9V analog voltage) and 3 extended output control interfaces (on/off: DC12V/0V).
3. Actively send daily information to the administrator's mobile phone every day (optional function).
4. The host is compact and has two installation methods: card slot and screw.
