Product catalog summary

Introduction
This document serves as a comprehensive guide on Brodersen's electronic timers, detailing both multifunction and single-function models. These timers are designed for diverse applications and are available for DIN rail or 11-pole plug-in mounting. They operate within a voltage range of 10.5-265V AC/DC, providing flexibility across different environments.

Specifications
Brodersen timers feature multiple timing functions selectable via front-mounted rotary switches. Time ranges include 0.6-6 seconds, 6-60 seconds, 0.6-6 minutes, and 6-60 minutes. They are equipped with single or double relay outputs and LED indicators for relay status. The design ensures ease of adjustment and consistent quality.

Operation
Operation involves selecting the desired function using a rotary switch, which should be adjusted only when the supply voltage is disconnected. Key functions include on delay, on pulse, symmetrical recycler, and release delay, each with specific operational characteristics.

Technical Data
The timers offer high accuracy with a repeating accuracy of ±0.5% and a setting accuracy of ±10%. They can handle a maximum load of 8A/240V AC for SPDT relays and 5A/240V AC for DPDT relays, withstanding up to 10 million mechanical operations and 100,000 electrical operations at maximum load.

Wiring and Safety
Installation must comply with safety regulations, especially for supply voltages above 50V. Wiring diagrams are provided to ensure safe and effective installation.

Conclusion
Brodersen's electronic timers are versatile and reliable, suitable for a wide range of industrial applications. Their robust design and proven technology make them a preferred choice for equipment, control panels, and machinery worldwide.

Notes/Remarks

Double output relay available in S2/D2 versions.
Supply voltage must be applied for at least 100 milliseconds to prevent output relay from remaining activated after preset time.
Power supply must handle an in-rush current of at least 300mA during the 100 milliseconds start time.

Load Considerations

Reduction factor for inductive load provided, indicating need for RC-network to protect relay contacts when switching inductive loads.
Output load diagrams illustrate DC load characteristics and reduction factors for inductive loads.
