Saving you time & money solving challenging problems!
Providing Plant Process Information in Hazardous Areas and Extreme Environments
- FOUNDATION Fieldbus™ and PROFIBUS® PA protocols
- Handle up to 8 fieldbus variables
- Bus powered
- High contrast 86x45mm LCD screens with backlighting
- Intrinsically safe FISCO and non-incendive FNICO compliant
- FM approvals, plus ATEX and IECEx certifications
- Local access via push buttons
- Optional alarm outputs and remote push buttons for selected models
- Field models have GRP IP66 enclosures
- Panel mounting versions can be IP65 sealed to panel
Text and simple graphics can also be displayed by writing to the transducer block parameters to create a custom screen. 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.
Options include 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.
FOUNDATION Fieldbus™ versions work only in the Listener mode meaning that no host resources are used and no license fee invoked.
PROFIBUS® PA versions can be set for either Listener or Node operation.
Intrinsically safe and non-incendive INDICATORS have FM Approval for Canada in addition to the U.S.
