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.
