Bently Nevada 141377-01 1701/06 Isolator Terminal Base (ITB)

Description:

The 1701/06 Isolator Terminal Base (ITB) and 170190 Dual Galvanic Isolator comprise hazardous area solutions within the FieldMonitor system. These components facilitate intrinsically safe transducer installations without the need for external safety barriers. The FieldMonitor ITB and associated modules are designated for placement in non-hazardous, Division 2, or Zone 2 areas, while the connected transducers may be situated in Division 1, Zone 1, or Zone 0 areas.
