It is used for automatic communication between multiple field devices using 2G/4G enabled SIM cards. These units can communicate to each other through centrally hosted MQTT broker. MQTT broker is hosted on cloud orstatic IP. Thus, these units establish a transparent data link for any external Field devices such as PLC and RTU

Remote Monitoring, Remote Diagnostic and Predictive maintenance is the need of the hour. System upkeep time is vastly improved if the key decision makers are immediately alerted on failures occurring in a system. Change in process conditions like increase or drop in Temperature, Pressure, Flow etc or a Solenoid valve / circuit breaker trip or a forced entry in your house can be alerted via SMS SAN designed a 2G/4G based embedded Alert system with multiple Analog / Digital Input & Digital Output catering to various applications.

Features

• Quick SMS alerts from field inputs
• Allows upto 4 Digital potential free inputs with common ground pin
• Supports upto 2 potential free outputs to be controlled via SMS
• For every input, unique SMS and prerecorded voice message can be sent to reporting numbers
• 10 numbers for SMS reporting and 10 separate numbers for voice reporting can be configured
• Voice reporting numbers can be landline or mobile numbers
• 16 seconds voice message recording for each input
• Voice message recording through mobile phone call
• Periodic update of Digital inputs status as Normal or Alarm via SMS
• Buzzer for audible status
• Configuration via preformatted SMS 

It is a 2G/4G based embedded Quick SMS alert System for field inputs with multiple Analog / Digital Input & Digital Output catering to various applications such as, Remote Monitoring, Remote Diagnostic and Predictive maintenance.

It is used for remote monitoring of field equipment via2G/4G network. It provides reliable data connection between central monitoring software and remote field device. It is designed to be used in industrial applications and operates on 18V-36V DC power supply. It can also support industry popular protocols such as MODBUS RTU for capturing data from field equipment and make it available to SCADA systems.
