Photorelay with relay output ФР102 (twilight switch)

Purpose:

Intended for switching street lighting on and off automatically; it can also serve as an element of automatic control for other devices according to light level.

Key features:

• Photorelay with a relay output.
• The light-sensitive element is a ФД-1 photodiode or an СФ2-5 photoresistor.
• The relay has a manual trip-level adjustment.

Specifications:

• Supply voltage 220 V, 50 Hz
• Power consumption 3 W
• Trip threshold adjustment range: (0.5–8) lx
• Operating temperature range: (−25 … +55) °C
• Storage temperature (−40…+70) °C
• Weight, max. 54 g.
• Overall dimensions (86×65×36) mm
• Protection class to EN 60529/IEC 529: — relay IP40; — terminal blocks IP20
• Mounting and external terminal connection: — for DIN-rail mounting; — incoming conductors connected via terminal blocks.
