Radio & GSM Telemetry \ GSM / GPRS Telemetry Systems and SMS Alarm Units \ IN4MA Remote SMS, Email & Web Based Monitoring System

Product details

The unit has 4 inputs which can be individually configured for 4-20mA, 0-10v or digital state. The unit is battery powered and can run for up to 3 years with a 15 minute monitoring cycle. The system can be user configured to send email or text messages to up to 4 mobiles, on alarm, or at a preset interval. The integral GSM modem has triple band 900/18001900 MHz capability to allow operation on all GSM networks worldwide. Supplied in a weatherproof IP67 case.

Utilizing the latest microprocessor technology coupled with state of the art GSM engineering, the new IN4MA monitoring  unit provides the most economical solution for remote telemetry with the added advantage of being self powered, to ease installation and maintenance.

The use of GSM (mobile phone) as the means of communications means there is no need to install a phone line, making the system flexible, portable and removes the need for customer interaction. Information and alarms can be sent by email, text message, gsm data call or by GPRS and viewed on either your mobile phone or on the internet via a secure username and password.

The unit can be programmed locally or remotely. When local the user has a series of pushbuttons and an LCD display making the process very quick and easy - there is little training involved.

• The IN4MA unit includes sensor excitation
• Monitor your assets from anywhere in the world
• Integral Programmable Processor
• 4 inputs, programmable to be analogue or digital
• Data sent periodically or on alarm
• Battery powered- typical life in excess of 5 years
• Graphical display to help with configuration
• Tri band GSM for global operation
• Data sent directly to your mobile phone
• Data can be viewed on the internet (additional fee will apply)
• Data can be viewed from your email

Modes of operation
Normally the unit will be ‘asleep’ with just the processor running. The Processor will wake up various components as and when required. For example, the processor will provide an excitation voltage of 21 volts to sensors before taking a reading – the length of time the processor gives for a sensor to settle to an accurate reading is configurable. The processor will also provide a wetting voltage of 3.6 volts for digital signals as and when required. When the IN4MA unit needs to communicate over the mobile phone network it will power up the GSM module and communicate with it as required. Whilst the modem is powered up it can also receive messages for changes in configuration. The LCD display shows the actions the IN4MA is performing.

The IN4MA will send email or text messages out of the box, all that is required is a suitable cell phone contract, typical costs can be as low as $20 per month.  Additionally its possible to view your data online using our web based application.  This will give you real time data along with a historical graphing.

Power Consumption
The integral battery has a capacity of 14.5 AH @ 3.6 volts. In sleep mode the IN4MA draws a miserly 50 micro amps. Performing additional functions, such as powering up a transducer, will drain the battery. Normally the biggest drain is powering up the GSM modem.

Configuration
The IN4MA can be remotely programmed by sending text messages, from either a mobile phone or from a pc with a GSM modem attached. The IN4MA will only receive the configuration messages when the GSM module is powered up. There is a free of charge windows based configuration tool available to simplify this process. You can also use the pushbuttons to change certain parameters, such as alarm thresholds and analogue scaling factors, locally.

Excitation
The IN4MA will power the sensors normally with 21 Vdc or 3.6 Vdc at a maximum of 200 mA.

Inputs
The 4 inputs are individually configurable to be 0-10 volts or 4-20mA. To configure the inputs you must adjust both the DIL switch on the unit and the configuration. For digital inputs set the system as 0-10 volts.

Quick and Easy Installation
The pushbuttons allow easy navigation of the menu system, so you can view the phonebook, the signal strength, the input values, the scaling and the alarm settings.
