GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM

LIGHT SENSOR - PSR SERIES

DESCRIPTION:

The PSR-1 is a Light Sensitive Resistor that may be used as
an input to indicate the presence of light at the sensor
location. The PSR-1-T is a PSR-1 coupled with a B420-P
transmitter. The PSR-1-T produces a 4 - 20mA output
signal. The sensor is designed to be mounted in the end
of a weatherproof conduit box.

SPECIFICATIONS:

PSR-1
Output (non-linear) >1 MΩ in dark

<1.5 kΩ in bright light

Temperature -25˚C to 75˚C
(-13˚F to 167˚F)

PSR-1-T
Power 12 - 35 VDC
Max current draw 22mA
Output (linear) 4 - 20mA (current

limited to 22mA)
Temperature -25˚C to 75˚C
(-13˚F to 167˚F)

APPLICATION:

The PSR-1 has a resistance in darkness in excess of 1 MΩ
and resistance in bright light of less than 1.5 kΩ.

The PSR-1 and PSR-1-T indicate the presence or absence
of light. They should not be used for foot-candle control of
occupied spaces. The PSR-1-T is calibrated for 4mA in
bright light > 100 foot-candles and 20mA in darkness <

0.1 foot-candles.
