Description
The PCR Series of photo controls is a combination of precision
electronic circuitry, electromechanical output, and unique
molded plastic housing. Designed and built to meet the
demands of the most rigorous requirement of tower and
obstruction lighting control, each unit is factory calibrated to
meet FAA and FCC specifications. Electronic circuit, output
contactor, and terminal block are all contained within front
plastic housing. Edge support molded into the bottom edge of
housing allows easy wiring of new and existing installations.
Available with or without cast aluminum junction box.
Operation
When the amount of light sensed falls below the actuation level
for energization, the output relay energizes. Conversely, when
the amount rises above the actuation level for de-energization,
the output relay de-energizes.

FEATURES BENEFITS
ABS plastic housing with
gasket seal
Withstands outdoor environmental hazards and
protects circuitry from moisture damage
Two 20A relay contacts Allows direct control of a lighting circuit without a
separate contactor
Fixed time delay Eliminates contact chatter
Reliable photo sensor Provides automatic lighting circuit operation from
dusk to dawn
