162459 Trendmaster Galvanic Isolator(TMGI)
Datasheet

Bently Nevada Machinery Condition Monitoring162513 Rev. JDescription
The Trendmaster Galvanic Isolator enables the Trendmastersystem to connect to intrinsically safe transducer
installations without the need for safety barriers or the needto specify, install and maintain a high integrity IS earth. The
Trendmaster Galvanic Isolator provides an interface between
Trendmaster scanning hardware, and all associatedProgrammable Transducer Interface Modules (ProTIMS)
located in a hazardous area.
ll

The Trendmaster Galvanic Isolator is powered from anexternal power supply which enables several GalvanicIsolators to be connected in parallel to one TIM line fromDSM or SPA.
Each Galvanic Isolator can interface and power up to32 ProTIMs, with a maximum cable length of 3,500 ft (orshorter, as limited by the hazardous area).
