Part Name Function of the part
Vibration A galvanic isolator that isolates safe-area
Transducer circuitry from hazardous-area circuitry.
Interface Module
Backplane A circuit board that distributes power to
(Vibration) the Vibration Transducer Interface
modules and sends transducer output
signals to the 3500 Monitoring System.
The backplane is a safe-area component.
An 8-position backplane for proximity and
acceleration measurements is used with
the 3500/40, 3500/42, 3500/44 and
Backplane
3500/50 Monitors. A 4-position backplane
(Keyphasor)
for Keyphasor measurements is used
with the 3500/25 Keyphasor Monitor.
Hazardous Area A screw clamp connector for attaching
Connector transducer wiring to the hazardous area
terminals at the top of the Vibration
Transducer Interface module.
Interface Cables Cables that interface the backplanes to
the 3500 Monitoring System. Order these
separately.
Earth Rail An accessory that comes with the
backplane and provides a convenient
earth termination point.
