are an additional facility for the M30 Autodialer to enable it to process up to four (Upgradeable) of the following types of signal:
4 to 20 ma, 0 to 10 ma, 0 to 20 ma
Certain other “common” options are also available including Isolated and fully floating
The M30 Autodialer Analogue Module connects directly in to the M30 Autodialer unit with a 10 way dedicated cable. It can accept the above inputs to provide information and/or initiate a dial out routine when pre-set high and/or low alarm trip-points values are reached or exceeded.
In addition to a dial out the M30 can initiate on site alarms e.g. sounders, local area pagers.
Trend indication is available to differentiate between rising or falling levels.
Rate of change is also available
All settings are user configurable.
The Data Logging feature enables the M30 Autodialer to store analogue and digital information that can be automatically or manually retrieved either via a telephone or downloaded to a computer running the M30 Datalogging software. This can then be displayed as a spreadsheet, bar-chart, pie-chart or line chart. The user can select the number and type of readings to analyse. The ‘raw’ data can be imported into any spreadsheet program.
Additional data logging storage memory can be added where more frequent sampling is required or where longer time spans between downloads are required.
