Brief introduction

RTU5023/6/7/8/9 provide 1 input for temperature,humidity,analog,power voltage,power status monitoring and alarm.When the temperature, humidity, 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.

RTU5023/6/7/8/9 Monitor Alarm unit can be used for temperature,humidity,4~20mA/0~5V analog signal,DC voltage,3 phase power status,single phase power status 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.
