Overview
The Siemens 3RA2813-1FW10 is a high-performance, solid-state time-delayed auxiliary switch designed to enhance the functionality of Siemens 3RT20 contactors and 3RH2 contactor relays. This ON-delay timer module provides a reliable solution for time-critical industrial applications. With a wide time range of 0.05 to 100 seconds and a versatile control supply voltage of 24-240 V AC/DC, this unit offers exceptional flexibility.
Its integrated varistor protects the contactor coils by providing attenuation, ensuring a longer lifespan for your equipment. Featuring a simple screw terminal connection and a convenient front snap-on design, the 3RA2813-1FW10 is easy to install and integrate into new or existing control systems.
Key Features & Benefit
- Solid-State Reliability: Provides accurate and consistent timing, eliminating the wear and tear associated with mechanical components.
- ON-Delay Function: Delays the operation of the connected relay, ideal for applications requiring a specific time-based sequence.
- Versatile Time Range: Adjustable timing from 0.05 to 100 seconds to suit a wide variety of industrial processes.
- Broad Voltage Compatibility: Operates on a wide range of control supply voltages (24-240 V AC/DC, 50/60 Hz), simplifying integration into diverse electrical systems.
- Integrated Varistor: Protects the contactor coils from voltage spikes and surges, extending their service life and ensuring system stability.
- Easy Installation: Designed for tool-free, front-mounting installation on Siemens 3RT20 contactors and 3RH2 contactor relays.
- Flexible Contact Configuration: Equipped with a 1 Normally Closed (NC) and 1 Normally Open (NO) relay contact, allowing for versatile control circuit design.
- Secure Connection: Utilizes robust screw terminals for a reliable and secure electrical connection.
Function
The Siemens 3RA2813-1FW10 functions as an ON-delay timer. When the contactor or contactor relay coil is energized, the module’s internal timer begins counting. After the preset time has elapsed, the auxiliary contacts (1 NC + 1 NO) switch their state. The Normally Open (NO) contact closes and the Normally Closed (NC) contact opens. This functionality is crucial for controlling sequences, ensuring equipment start-up delays, or managing staggered operations in automated systems.
