What can the MELBOX do?

Remote transmission of digital switching signals and analog (0-10V or 4-20mA) signals over the Internet.

Remote control and remote monitoring of machines and systems via the Internet.

Alert and report via push notification to the app, SMS as a fallback level (subject to a charge).

Features That Matter

The Reasons You’ll Love It

safety

How safe is MELBOX against hacker attacks?

encryption + coding

All transmissions between the MELBOX and the server are cryptographically encoded using a constantly changing key and encrypted again using SSL.

speed

How fast are the signals transported from one MELBOX to another?

in 1 - 2 seconds

The signals (whether digital or analog) are transmitted from one MELBOX to the other within 1 – 2 seconds.

exactness

With what tolerance are the analog data transmitted?

1% tolerance

Precision components guarantee a tolerance of less than 1% when transferring the analog values.

reliability

What does the MELBOX do if the internet connection fails?

3 ways to the Internet

The MELBOX automatically switches between cable connection, WLAN and surf stick (mobile phone) in the event of a failure.

retrofit

Is the MELBOX suitable for retrofitting?

Suitable for retrofitting

The MELBOX can be screwed directly onto the wall. It is splashproof and dustproof.

warranty

As long as there is warranty on the MAILBOX?

2 years warranty

The MELBOX hardware warranty is at least 2 years. Service and spare parts are guaranteed by Nagl Elektronik for another 10 years.

Practical examples

Fernsteuern über Internet

Water supply with elevated tank

An elevated tank supplies drinking water to a city. The level is measured using a field device. The analog output signal is 4 – 20mA.

Internet cloud or the MAILBOX server

The configuration, how the signals are to be linked or changed and to which MELBOX the result should be sent is stored in the MELBOX server.

Pump switches when the level is low

The pump switches on depending on the level in the high tank -> fills the high tank and switches off when the upper level is reached.

1st example

remote control over internet

MAILBOX sends fill level. App with switch.

The analog signal A1 (4 – 20mA) is transmitted from the MELBOX to the server. With the MELBOX App, the pump can be remotely controlled at any time (S1).

Threshold switch and OR gate

A threshold switch converts the analog signal into switching signals for the upper and lower level. The switching signal of the MELBOX app is linked via an OR gate.

Switching on the pump remotely

With another MELBOX, the pump can be switched on over a large distance (relay output 250VAC / 4A).

2nd example

Motor protection switch trips

A motor protection switch trips and an auxiliary contact (D1) is connected to an input of the MELBOX.

Time Delay

In addition to gates, time delays can also be programmed in the MELBOX server. In this case, it is used to not report a brief fault.

Alarm via push notification

The alarm is reported to the MELBOX App via push notification. SMS, Facebook messenger and email for alarm or event reporting are also to be selected.

About us

Nagl Elektronik was founded in 1992

Since 1998 everything has been about SMS. We developed the HomeWatcher for remote control of the heating and alarm system for weekend homes. The.Blue.Box-II is a reliable device for alarming via SMS at many fire departments at home and abroad.

For Coca-Cola we have developed devices for the purchase of drinks via SMS on the Coca-Cola vending machine.

MELBOX is a signal transmission system with powerful hardware and internet web application with SQL database.
