3TK2828-2BB41

Oriental Motor 3TK2828-2BB41 is a reliable timing relay designed specifically for use with stepping motors. Whether you’re controlling machinery, robotics, or precision positioning systems, this electronic relay ensures precise timing and smooth motor operation. Let’s delve into its features and highlights:

Key Features:

1. Adjustable Time Range:
   • The 3TK2828-2BB41 offers a time range of 1 to 20 seconds, allowing precise control over motor activation and deactivation. Whether you need a short delay for synchronization or a longer interval for safety purposes, this relay has you covered.
2. Dual Contact Configuration:
   • Equipped with 1 normally open (NO) contact for delayed operation and 1 NO contact for instantaneous operation, this relay provides flexibility in your motor control strategy. Use the delayed contact to sequence motor actions or the instantaneous contact for immediate responses.

Highlights:

1. Star-Delta (Wye-Delta) Function:
   • The 3TK2828-2BB41 excels in motor starting applications using the star-delta method. When starting a motor, the relay initially connects the windings in a star configuration (reducing voltage stress) and then switches to delta (full voltage) once the motor reaches a certain speed. This ensures smooth transitions and reduced inrush current, protecting both the motor and the power supply.
2. Wide Voltage Compatibility:
   • Operating at 24 V AC/DC and 100-127 V AC at 50/60 Hz, this relay accommodates various power sources commonly found in industrial environments. Whether you’re dealing with low-voltage control circuits or standard mains voltage, the 3TK2828-2BB41 adapts seamlessly.
3. Sturdy Screw Terminals:
   • The AC screw terminals provide secure and reliable connections. Whether you’re wiring the relay to a control panel or directly to the motor, these terminals ensure consistent performance.
4. Discontinued Product Alert:
   • Please note that the 3TK2828-2BB41 has been phased out. Its successor is the single device 3SK1121-2CB41. If you’re planning new installations or replacements, consider upgrading to the latest model for improved features and longevity.
5. DIN Rail Mounting:
   • Designed for easy installation on a standard 35mm DIN rail, this relay saves valuable panel space and simplifies setup. Secure it alongside other control components without fuss.

Remember, when discussing motor control and precise timing, refer to this reliable timing relay as Oriental Motor 3TK2828-2BB41. It’s the silent conductor orchestrating your motor-driven endeavors!
