The R-Lite-Web is a low cost web enabled data logger. It is available with 2 4-20mA and 2 digital inputs ( state or counter ), or 4 digital inputs. The unit logs the value of each channel at up to 1 minute intervals and sends the data to a web page on a 6 hourly, daily or weekly basis. The data is displayed on the web page in chart and table views, and can be downloaded in XLS format from the browser. The R-Lite-Web can also send SMS text messages on alarm to up to 16 mobile phones, and has 1 relay output for remote control.
The R-Lite-Web is an easy-to-use GSM/GPRS data logger. It can log the status of 2 x 4-20mA inputs and 2 digital inputs at intervals from 1 minute to once per day. The integral GPRS modem sends the data via a GPRS socket connection direct to a web page at user defined intervals ( from once per minute to once per week ). Latest readings and historic data can be viewed on the web browser interface from any PC with an internet connection.
Alarm parameters can be set for the digital and analogue inputs to send text messages to up to 16 mobile phones for any alarm condition. The unit also has a relay output which can be triggered by an alarm condition or activated by sending the unit a text mesage.
The R-Lite-Web can either be used as standalone unit or it can be added to a PLC and can read all the PLC registers to provide a very cost effective solution for logging PLC data and publishing it to a web page.
Maintenance and configuration can either be done through the RS232 connector or from remote, using a cellular modem.
