RTU5027 provide 1 input for analog power status monitoring and alarm.When the analog, power voltage exceed high threshold or low threshold value, will send SMS alert to up to 10 preset mobile phone immediately.
Just dial from authorized user number, the Monitor Alarm unit will reject at the first “Ring”, no communication cost, and then return the current temperature, humidity, power status or voltage.It can report current status interval or daily.Moreover,it can also support Modbus RTU Over TCP and Modbus TCP to connect to cloud platform,then monitor the current status in real time through GSM/3G/4G network.
RTU5027 Monitor Alarm unit can be used for 4~20mA/0~5V analog signal monitoring and alarm, suitable for classrooms, public places, hospitals, stations, Food warehouses, offices, factories, libraries, laboratories, etc., and any place that requires and supports monitoring.
Key Features
- GSM/GPRS/3G/4G network communication, can be operated from anywhere, no distance;
- Multiple applications:temperature,humidity,power supply voltage,analog signal,3 phase power status, single-phase power status, etc.;
- Inbuilt MCU monitoring power supply input voltage value, measure range is 0~36V, no need additional sensor to save cost;
- Up to10 authorized phone numbers, 5 can be used to receive call or SMS,and 5 can be used to call and SMS while alarm occurrence;
- Can set timer report and every x hours automatically send its status/value to the first authorized number;
- Support remotely read historic data via SMS;
- Rechargeablebackup battery inside can last 8 hours;
- Modular structure design, replace a module can upgrade the network from 2G to 3G/4G or 3G to 4G;
- Compatible wall installation and DIN35mm industrial rail installation;
- Support Modbus RTU Over TCP and Modbus TCP, can be connected to cloud platform.
Typical Application Scenarios
It is especially used in classrooms, public places, hospitals, stations, food warehouses, offices, factories, libraries, laboratories, and any other places that require and support monitoring of temperature and humidity as well as power failure alarms.
