DMO1-201 WEB BASED DATA LOGGER With Control Function

The DAN DM01 is the basic monitoring system in the DAN range. It is installed in the field either as a land based or buoy based system. Configuration of the DM01 is accomplished by logging into the DAN website and entering the relevant information into the account pages. Note that the account is protected by a group name, user ID and password specific to each user and product.

The DM01 has 6 general purpose analogue inputs and one counter input. Each of the general purpose inputs are switch selectable to suite most industrial grade probes. Should probes need power supplied from the DM01 unit, separate power boards are available for this purpose. Battery voltage can be monitored if required.

The DM01 has a digital input suitable for counting pulses. The unit will capture all pulses up to a frequency of 4kHz.The DM01 has two software alarm points associated with each of its inputs. There are 3 relays incorporated to provide local control and alarm action. The relays can be associated with any input or combination of inputs.

The DM01 has on board batteries which will allow it typically to operate for 24 to 72 hours without external power. This time is dependant upon the type of transducers connected to the inputs and the duty cycle of the unit. If a dc supply is available at the site, the unit may be recharged by any available source of dc voltage in the range 10 to 50V. If mains power is available, a plug pack with an output in this range can be connected as the means of recharging the batteries. If no power source is available then solar cells can be directly connected and used as the means of recharging the batteries. DAN can supply solar cells and plug packs as part of the implemented solution.

The DM01 has an inbuilt GSM/GPRS modem that is used to communicate both data and control signals between the DM01 and the web server via the internet gateway provided by the mobile phone service provider. An option to use CDMA is also available at additional cost.Data is available by logging onto the DAN web site using password and logon ID. Full access to all the relevant information necessary to set up and run the unit is available. Total control of how much or how little information is displayed on the website can be managed. Data available includes data from the site, alarm messages generated and a log of all changes made to the system including details of the logon ID that made the change.The web site also provides facilities to set local control or alarm parameters, manage passwords and access permissions, input telephone numbers and email addresses for alarm notification and calibration of the inputs.Instantaneous data may be obtained form the unit by calling the unit from one of the authorised numbers noted into the web site by the user.
