2. Application examples
The following examples show some basic applications of smartDEN IP-Maxi. The
examples are only conceptual and additional equipment/connections can be required
in actual implementations.
2.1. Electrical appliances remote control applications
smartDEN IP-Maxi can be used to control remotely electrical appliances (Fig.
2.1). Up to 8 electrical devices connected to Relays can be controlled independently.
Various integration protocols (SNMP, HTTP/XML/JSON, Web-browser access) can
be used by any modern device to control the appliances from all over the world.

2.2. Monitoring and logging applications
smartDEN IP-Maxi can be used to build monitoring and logging systems. Up to 8
various kinds of sensors for temperature, humidity, distance, light etc. can be
connected to the Analog Inputs of the device (Fig. 2.2). Provided SNMP and
HTTP/XML/JSON APIs allow for easy integration with third-party applications.

2.3. Standalone applications with sensors and electrical devices
Once configured, smartDEN IP-Maxi can be used in standalone control
applications. For example, the events from Digital Inputs or threshold conditions of
single/differential Analog Inputs can be configured to control various devices
connected to Relay outputs (Fig. 2.3). In addition, a Week Schedule table for
switching Relays On/Off at specific time can be specified.

2.4. Events counter
smartDEN IP-Maxi provides 8 x 32-bit Counters (from 0 up to 232-1) attached to
the Digital Inputs that can be used to count various events - for example detect when
a person enters in a shop through the door (Fig. 2.4). Upon detecting the specified
edge/level condition smartDEN IP-Maxi increments the corresponding Counter. With
suitable software and database one could easily organize a simple monitoring and
statistic system.

2.5. Web based thermo-regulator
Each Relay can be set to work in Regulator mode where it can be controlled only
from an Analog Input. The controller can be configured to switch different Relays
upon the value of single/differential Analog Input (one input can control many
Relays). For example, one Relay can be set for heating, another for cooling and etc.
(Fig. 2.5). All the process may be monitored online and this makes smartDEN IP-
Maxi suitable for building standalone Web enabled thermo-regulators.

Another possible application for smartDEN IP-Maxi is differential thermo-regulator
very useful in cases when solar hot water panel must be monitored and controlled
based on two temperature sensors values. The first sensor monitors the temperature
of the panel water and the second monitors the temperature from the boiler water. If
the boiler water is cooler than the panel water, the valve is opened and the hot water
from the panel comes in to the boiler.

2.6. Home automation
smartDEN IP-Maxi can be used in a variety of home automation tasks:
Climate: heating, ventilation and air conditioning;
Lighting: switching On/Off the electric lights in the house;
Shading: opening and closing the blinds and curtains;
Security: monitoring and control of central locking, doors and windows, etc.
A number of flexible control schemes can be set up, for example:
Use of Regulator mode of the Relays for opening and closing the blinds and
curtains depending on the level of the outside sunlight;
Use of Pulse mode of the Relays for controlling garage doors, windows, roofs
and for any other application where a certain period of time should be
maintained, etc.;
Use of integrated Week Schedule features to switch On/Off appliances up to
30 times per day in a standalone mode;
Use of “many inputs to one relay” controlling mode – each Relay can be
paired simultaneously with a Digital Input (button, switch...), Analog Input
(sensor for temperature, humidity, distance, light...), Week Schedule
command, as well can be controlled remotely (browser, SNMP,
HTTP/XML/JSON).

2.7. Irrigation systems
Other applications of smartDEN IP-Maxi include irrigation systems. Two different
modes can be combined:
Start and stop the irrigation at specific times using the Week Schedule
features;
Start and stop the irrigation depending on humidity level by applying a control
loop including a humidity or rain sensor and solenoid valve controlled by a
Relay.

5. Installation
This device must be installed by qualified personnel;
This device must not be installed directly outdoors;
Installation consists of mounting the device, connecting to an IP network,
connecting sensors, providing power and configuring via a web browser.
5.1. Box mounting
smartDEN IP-Maxi can be mounted to a standard (35 mm by 7.55 mm) DIN rail
(Fig. 5.1). Attach the module to the DIN rail by hooking the hook on the back of the
enclosure to the DIN rail and then snap the bottom hook into place.

5.2. Power supply
smartDEN IP-Maxi must be powered with 12V DC stabilized and filtered voltage.
After power on, the power led must be on and STATUS indicator must start blinking
in 5 seconds which means the module is running normally (Fig. 5.2).
Figure 5.2. smartDEN IP-Maxi power supply
Please keep the polarity and the power supply voltage range!
smartDEN IP-Maxi does not accept AC power supply voltage. It is highly
recommended to check the power supply source parameters before the
module is powered on.
The power supply equipment shall be resistant to short circuit and overload
in secondary circuit.
When in use, do not place the equipment so that it is difficult to disconnect
the device from the power supply.
