Finder 11 Series 16A Light-Sensitive Relay

Product Overview

The Finder 11 Series 16A is a high-performance light-sensitive relay designed for the automatic control of lighting systems based on ambient light levels. It includes a separate light sensor and is engineered for reliability in demanding environments, meeting standards such as EN 45545-2 for fire protection and EN 61373 for vibration and shock resistance.

Key Features

• Sensitivity Adjustment: Adjustable range from 1 to 100 lux.
• Installation Assistance: For the first three operating cycles, the switching delay is reduced to zero to facilitate setup.
• Safety: Features SELV isolation between contacts and power supply, and double insulation between the power supply and the light sensor.
• Status Indication: Integrated LED for clear operational status monitoring.
• Durability: Cadmium-free contact materials and light sensor components.

Technical Specifications

• Contact Configuration: 1 NO (SPST-NO) 16A contact.
• Rated Voltage: 250/400 V AC.
• Power Supply: 12-24 V AC/DC.
• Switching Delay: 1 second for ON, 6 seconds for OFF.
• Operating Temperature: -25 to +55 degrees Celsius.
• Protection Rating: IP 20 for the relay, IP 54 for the light sensor.
• Mounting: 17.5 mm wide, suitable for 35 mm rail (EN 60715) mounting.

Installation and Operation

The device is designed for easy integration into electrical cabinets. Ensure that the light sensor is positioned to accurately detect ambient light without interference from the controlled light source. The relay features a clear LED indicator to show the current state of the output contacts. During the initial installation phase, the zero-delay feature allows for immediate testing of the lighting circuit.

Maintenance and Disposal

The relay is designed for long-term operation with minimal maintenance. Periodically check the light sensor for obstructions or dirt that could affect sensitivity. Ensure all electrical connections remain secure. At the end of its service life, the device should be disposed of in accordance with local environmental regulations regarding electronic waste.
