These bus powered instruments, which can display up to eight
fieldbus process variables on a 86 x 45mm screen, are available for use
with Fieldbus Foundation or Profibus PA systems.
One, two or four fieldbus variables may be displayed at
the same time, together with units of measurement and tag information.
The operator can select the displayed screen via the front panel push-buttons,
or these buttons may be disabled.
By writing to the transducer block parameters, text and
simple graphics can also be displayed. The push-buttons can then be used
to return operator acknowledgements: if large industrial push-buttons
are required for these operator inputs, external push-buttons or switches
may be wired to the instrument.
The field mounting models are housed in a robust IP66 glass
reinforced polyester (GRP) enclosure with a toughened glass window that
may be surface mounted, or pipe mounted using one of the accessory kits.
The panel mounting models have an IP66 front panel with a gasket to seal
the joint between the instrument and the panel.
Instruments can be supplied with six isolated alarm outputs,
each of which may be linked to any of the displayed fieldbus variables.
Alarm setpoints can be entered via the front panel push-buttons which
may be protected by a security code.
The two intrinsically safe models, which have ATEX, FM and
IECEx certification, comply with the Fieldbus Intrinsically Safe Concept
FISCO.
