A-B 700-FSY2DU23 Safety relay

Product Dimensions：

The Allen-Bradley 700-FSY2DU23 is a High Performance Timing Relay, specifically designed for motor control applications requiring sequential starting.

✨ Product Advantages (Features)

The 700-FS series of high-performance timing relays offers several key advantages:

• 
  

• Star-Delta Specific Functionality: Specifically designed and pre-configured for Star-Delta (Wye-Delta) motor starting, ensuring proper timing sequence for a smooth transition from Star to Delta.

• Dual Voltage Coil: The single unit can operate on a wide range of both AC and DC control voltages (24−48V DC and 24−240V AC), simplifying inventory and selection.

• Adjustable Time Range: The timing range is adjustable, allowing users to fine-tune the transition time (1.5 to 30 seconds) based on the specific motor and load requirements.

• Space-Saving Design: The 22.5 mm width allows for efficient use of panel space when DIN rail mounted.

• High Performance/Durability: Classified as a "High Performance" relay, indicating robust construction, high mechanical life (up to 30,000,000 cycles), and reliable operation.

• Coil Surge Protection: Built-in protection helps prolong the life of the relay by guarding against transient voltage spikes.

⚠️ Important Notes (Precautions)

• Product Status: This model, 700-FSY2DU23, is discontinued. If purchasing, ensure you are buying from a reputable vendor and are aware of the replacement model (e.g., 700-FSY7UU23 or equivalent) for future maintenance.

• Installation Environment: Adhere to the specified operating temperature range (−25 to 60∘C open). For applications in harsh or hazardous locations, ensure the unit meets the required certification and consider using an appropriate enclosure.

• Wiring/Terminals: The terminals are typically finger-safe, but all installation and wiring must be performed by qualified personnel in accordance with local electrical codes and the manufacturer's instructions.

• Motor Sizing: The Star-Delta timing setting must be correctly matched to the motor's acceleration time to prevent damage to the motor or load. Setting the time too short or too long can cause issues during the transition.
