Computer room power failure alarm acquisition converter

Product introduction

RS-*-GPRS is a terminal device suitable for field equipment monitoring and wireless transmission through GPRS. It is widely used in outdoor weather stations, farmland water conservancy, intelligent agriculture, and centralized monitoring of various industrial instruments. the device has four analog signals (4~20mA/0~5V/0~10V) for acquisition and four channels for switching signals (dry contact or active signal). Only one mobile phone card with data traffic (mobile or Unicom) is needed, and the device can be monitored remotely by using less than 30M per month. the product has been waterproofed and can be used in the wild rain and snow environment for a long time.
the equipment can be powered by AC 220V or DC 12V, which can be adjusted on site according to actual conditions. Generally, in the case of mains, AC 220V is used to supply power to the equipment. In the absence of mains, 12V solar panels are used to supply power to the equipment.
the parameter setting and inquiry of the product are completed by SMS, which is simple and convenient; the data is regularly uploaded by SMS, and the upload interval can be set. the data can also be uploaded to our environmental monitoring cloud platform (neutral interface) through GPRS. the name, unit and conversion function of the instrument can be customized on the cloud platform. We also have a free APP (completely neutral) for our customers. For customers who build their own servers, we provide a free environment monitoring platform (RS-RJ-K). The software also supports custom data names, units, and conversion functions. The device supports over-limit SMS alarm and ringing voice alarm, and can realize real-time monitoring of data offline.

 

  

 

Application scenario
1. Network use: the data of the on-site analog type (4~20mA/0~5V/0~10V) or the on-site switch status can be transmitted back through GPRS to achieve centralized monitoring of data.

2. Stand-alone use: the data of the on-site analog type (4~20mA/0~5V/0~10V) or the on-site switch status can be sent to the target mobile phone by SMS. It can also be queried at any time via mobile phone. On-site data, when the on-site data is over-limit, it is to send a text message to the target mobile phone number.
