Data Loggers For Solar Applications

We are offering 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:
1. Direct usb (for distances not more than 3 meters)
2. Rs232 (for distances not more than 100 meters).
3. Rs485 (for distances not more than 1 km)
4. 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:
1. 4 line x 16 characters alphanumeric display for display of process values, settings, etc.
2 keys: set, inc, dec, hld, esc 3. 'buffer full' (bf) indicator lamp
4. 'logging enabled' (le)indicator. 5. 'overwrite(loop) mode on' (owr)indicator.
6. 'display hold'(hld) indicator. 7. 'communication in progress'(com) indicator.
