In today’s modern lighting systems, efficiency and flexibility are two key aspects that are increasingly in demand. One of the most reliable solutions for this need is the impulse relay—an electrical device that allows you to control lighting from multiple switch points. Theben, a leading name in building automation technology, introduces two of its top impulse relay models: OKTO S12-230 and OKTO ES12-230.
Both are designed to simplify electrical installations in areas such as corridors, hallways, hotels, private homes, and commercial buildings. This article examines the characteristics, technical details, and distinctions between the two models to assist you in selecting the most suitable option for your requirements.
What Is an Impulse Relay?
An impulse relay is an electrical switch used to control one or more lights from multiple push-button switches. When any button is pressed, the relay receives an electrical pulse that changes the contact position—turning the light on or off. This setup is far more efficient than traditional multi-way switch wiring, especially in spaces where lights need to be operated from various locations.
Theben OKTO S12-230: Electromechanical and Reliable
The OKTO S12-230 is an electromechanical impulse relay that uses a mechanical switching mechanism to change contact positions. It's an ideal solution for standard installations in public corridors or hallways.
Key features of OKTO S12-230:
-
Single channel with normally open contact: Ideal for managing one main lighting circuit.
-
Simple installation: Requires only two wires per push-button switch, making installation faster and easier.
-
Manual override switch: Built-in switch allows for manual operation when needed.
-
Energy-efficient: Consumes no power in standby mode.
-
High compatibility: Supports LED loads up to 200 W and incandescent/halogen loads up to 1800 W.
-
High switching capacity: Handles up to 16 A at 230 V AC.
-
Sturdy design: Housing that is heat-resistant and self-extinguishing, featuring an IP20 protection rating.
-
Installed on a DIN rail: Takes up one standard DIN module space.
Thanks to its ability to operate in temperatures up to 60°C, the OKTO S12-230 offers strong and stable performance even in challenging environments.
Theben OKTO ES12-230: Electronic, Silent, and Modern
The OKTO ES12-230 is an electronic impulse relay designed for quiet operation, making it ideal for noise-sensitive environments such as hotels, bedrooms, or study areas.
Advantages of OKTO ES12-230:
-
Silent operation: Switches without the usual clicking sound—perfect for peaceful spaces.
-
Efficient performance: Optimized for LED lighting with minimal power consumption and high efficiency.
-
Electronic bistable function: Maintains the switching state without significant standby power.
-
Multi-point control: Allows control from multiple push-buttons with no meaningful energy loss.
-
Modern installation: Easy to integrate and environmentally friendly.
Using electronic technology not only adds long-term reliability and extended lifespan, but also enhances acoustic comfort for a quieter environment.
