DESCRIPTION
The FCA-150 series relay is a polarized, single-side stable design, where the flux
from a permanent magnet provides the armature holding force in the deactivated
state, and its flux path is switched and combined with the coil flux in the
operated state. This results in appreciably increased contact pressure in both
states over that of a spring return non-polar design. The FCAC-150 series has a
1 Form C (SPDT) auxiliary contact set rated at 2 Amps available.
Designed and built to perform under the most demanding environmental
conditions and can withstand such changing environmental factors as temperature,
altitude, shock, vibration, and salt spray.
Minimum mechanical life expectancy is 50,000 cycles under resistive load.
3 available coil voltages (6, 12 and 28 Vdc) with optional transient suppression.
