Solar Data Loggers

We are offering advanced Solar Data Loggers.
Introduction :

• The unit scans 16 inputs, and stores the readings with a time stamp in its memory, at user-set intervals.
• The user may easily program the input type (thermocouple, rtd, 4-20ma, 0-10v), and also calibrate the same individually from the front panel.
• Two relays are provided to be energized when one or more readings exceed user-set high & low limits.
• It also transmits in real time the readings over a communication interface at user-set intervals the user can also see a dump of all accumulated data at any time.
• The data is transmitted to the user's pc in a format readily opened by a spreadsheet such as ms-excel the unit will also scroll on its front panel display the readings of each input, along with the channel number, and the high low limits for that channel.
• The unit maintains a 100 year real time clock calender, which may be set by the user.

The communication interface is one of the following, based on your model :

• Direct usb (for distances not more than 3 meters)
• Rs232 (for distances not more than 100 meters).
• Rs485 (for distances not more than 1 km)
• Ethernet (for large distances over lan & internet)

User Interface :
The front panel is described below (fig – 1).
The main components of the front panel are :

• 4 line x 16 characters alphanumeric display for display of process values, settings, etc.
• Keys : set, inc, dec, hld, esc
• 'buffer Full' (bf) indicator lamp
• 'Logging Enabled' (le) Indicator.
• 'Overwrite (loop) mode on' (owr)indicator.
• 'Display Hold'(hld) Indicator.
• 'Communication in Progress' (com) indicator.
