Series 11 modular light dependent relays (LDRs) from Finder are designed for automatic control of lighting circuits based on ambient light levels. These compact DIN-rail mounted devices integrate a photoelectric sensor and a relay output rated from 12 to 16 A, typically available in 1-pole (1P) configurations. They operate at standard mains voltages (e.g., 230 V AC, 50/60 Hz) and feature adjustable light thresholds, hysteresis settings, and time delays to prevent flickering. The modular design allows for easy installation in distribution panels, with optional accessories like remote sensors or manual override switches. These relays are ideal for dusk-to-dawn lighting control, offering reliable switching for resistive and inductive loads.
Applications for Series 11 relays span across commercial, industrial, and residential sectors. They are commonly deployed in outdoor lighting systems such as streetlights, parking lots, facades, and billboards, as well as indoor environments like warehouses, corridors, and stairwells where energy efficiency is critical. In industrial automation, they integrate into building management systems (BMS) for centralized lighting control, reducing energy consumption by ensuring lights operate only when needed. Their robust construction suits harsh environments, with IP20 protection for indoor use and optional enclosures for outdoor installations.
The main subcategories within this series include the 11.21 (12 A, 1P, adjustable threshold) and 11.31 (16 A, 1P, with time delay). Article codes typically follow the pattern "11.xx.xxx", where the first two digits denote the series, the next two indicate the current rating and pole count, and the final digits specify features like voltage or accessories. For example, 11.21.8.230.0000 represents a 12 A, 1P relay for 230 V AC. Other variants include models with fixed or adjustable light levels, and versions with integrated or remote sensors.
