Siemens 3RT1926-2EJ21 Solid-State Time-Delayed Auxiliary Switch for 3RT1 Contactors Original Brand New

Overview

The Siemens 3RT1926-2EJ21 is a high-quality, solid-state time-delayed front-side auxiliary switch designed to integrate seamlessly with Siemens 3RT1 contactors. This compact and reliable module provides essential timing functions for a wide range of industrial applications, ensuring precise control and enhanced system automation. With an adjustable time range of 0.5 to 10 seconds, it offers the flexibility needed for various control schemes.

Key Benefit

• Enhanced Automation: Adds a time-delayed switching function to your 3RT1 contactor setup, enabling more complex and automated control sequences.
• Increased Reliability: Solid-state technology ensures a longer lifespan and greater resistance to mechanical wear compared to traditional electromechanical timers.
• Space-Saving Design: Its front-side mounting minimizes the footprint on your control panel, allowing for more compact and efficient panel layouts.
• Simple Integration: Designed specifically for the Siemens 3RT1 series, it offers quick and easy installation without the need for complex wiring or modifications.
• Versatile Power Compatibility: Operates on both 24 V AC/DC, making it suitable for a broad range of power supply configurations.

Function

• ON-Delay Function: The switch activates its contacts after a preset time delay has elapsed, providing a critical function for sequencing operations, motor start-up delays, and preventing simultaneous device activation.
• Configurable Time Range: The adjustable knob allows users to precisely set the time delay from 0.5 to 10 seconds to meet specific application requirements.
• Contact Configuration: Features one normally open (NO) contact and one normally closed (NC) contact, offering versatile control options for different circuit designs.
