The Parts of the Interface System
Part
Part Name
Function of the part
Vibration
Transducer
Interface Module
A galvanic isolator that isolates safe-area
circuitry from hazardous-area circuitry.
Backplane
(Vibration)
Backplane
(Keyphasor)
A circuit board that distributes power to
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
3500/50 Monitors. A 4-position backplane
for Keyphasor
measurements is used
with the 3500/25 Keyphasor Monitor.
Hazardous Area
Connector
A screw clamp connector for attaching
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.
Also included with the standard interface system package are a mounting kit and
a manual. The mounting kit contains the following parts:
