The iRIS 150FX is a small, compact datalogger featuring an LCD display and keypad. It can be connected to a wide variety
of sensors, and features two analogue (0 - 5 V, 0 - 20 mA) inputs, two digital inputs, SDI-12 serial instrument support and
a single digital output for alarm or control purposes.
The iRIS 150FX is supplied in a powder-coated die-cast aluminium enclosure. Power supply and I/O connections are
provided by a small screw terminal block within the unit. Cable access is via two NG12 glands on the bottom edge of the
enclosure. A small text/graphics LCD provides the user display and user input is via a four key keypad in the same style as
other iRIS dataloggers.
The iRIS 150FX supports a maximum of six virtual sensors, the sources of which can be chosen from a range of physical
digital or analogue types. Each sensor can be checked for up to six separate alarm conditions, each with separate trigger
and reset levels. Each alarm also has an optional duration, which is used to delay the alarm trigger for analogue inputs
and to determine the time over which pulse input counters should be totalised (rainfall, flow meter pulse etc.). Data is
logged in a four word (8 byte) compressed format which includes full date and time to fractions of a second.
The alarm(s) can be linked to the digital output to activate external equipment when one or more alarms are activated in
the event of alarm activation.
