PCR SERIES

Photo Control

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.
