Electronic Vibration Switch
5477 2-Wire Design for Upgrading Existing Mechanical Installations
The Model 5477 features two-wire hookup and solid state reliability.
This makes it an ideal replacement for mechanical vibration switches
when increased accuracy and repeatability are required.
SEISMIC PRODUCTS
Powered by an AC or DC control circuit, the unit closes or interrupts
the circuit when the base vibration level exceeds the field adjustable
setpoint. Separate start-up and monitor delays prevent nuisance
trips. A flashing red LED illuminates upon a tripped condition and
an optional LCD digital indicator provides a convenient display of
vibration level.
The removeable electronics module plugs into the weathertight,
explosion-proof aluminum housing. The wire entry is sealed
against moisture. An NPT stud provides a rigid, single hole mount
to machinery.
