DK22F7 TELEMECANIQUE Latching Relay

Review TELEMECANIQUE Latching Relay Ca2

The Telemecanique DK22F7 Latching Relay CA2 is a versatile and reliable electronic switching component designed for various automation applications. This latching relay from Telemecanique, a leading manufacturer in industrial automation, is suitable for handling currents up to 10 Amperes and voltages up to 250 Volts AC or 30 Volts DC.

The DK22F7 features a compact size of 42.5 x 29.5 x 17.5 mm (L x W x H) and a weight of only 115 grams, making it an ideal choice for space-constrained installations. Its robust design ensures long-lasting performance even in harsh environments, with a rated operating temperature range of -25 C to 70 C.

This latching relay comes with two normally open (NO) contacts and two normally closed (NC) contacts. When the coil is energized, the contacts change their states, making it ideal for applications requiring one-way switching that stays in the new position until the coil is de-energized. The contacts are rated for a contact current of 10 Amperes and contact voltage of 250 Volts AC or 30 Volts DC, and they provide a contact resistance of less than 50 milliohms.

The DK22F7 Latching Relay CA2 offers excellent electromagnetic compatibility (EMC) with a maximum radiated emission of 30 dBm and a maximum conducted emission of 100 V/m. It also complies with various industry standards, including EN 61850-3, EN 60947-5-1, and EN 60947-5-2.

This latching relay features a coil with a resistance of 280 ohms and an inductance of 0.14 mH, ensuring fast response times. It also has a thermal time constant of 1 second and a contact bounce time of less than 10 milliseconds, ensuring smooth and reliable switching.

The Telemecanique DK22F7 Latching Relay CA2 comes with a mounting base that allows for easy and secure installation in DIN rail mounting systems. Its terminal block is designed for easy and secure wire connection, and it is suitable for use with both solid and stranded wires.

In summary, the Telemecanique DK22F7 Latching Relay CA2 is a high-performance and reliable switching component suitable for various automation applications. Its compact size, robust design, and excellent EMC compatibility make it an ideal choice for space-constrained installations, while its fast response times and reliable contact switching ensure smooth and efficient operation.

The Telemecanique DK22F7 is a latching relay with a coil voltage of 24V DC and a contact rating of 10A. Here are some pros and cons that may help you make a decision about purchasing this relay:

1. Robust Design: Telemecanique relays are known for their high-quality and robust design, making them suitable for industrial applications.

2. Latching Relay: Latching relays retain their contact position even after the coil voltage is removed, which is ideal for applications where the contact needs to remain closed or open after the power is turned off.

3. Compact Size: The DK22F7 has a compact size, making it easy to install in tight spaces.

4. Versatile: The relay can be used in various applications, including automation, control systems, and power distribution.

5. CE certified: The relay is CE certified, which means it complies with European Union safety, health, and environmental protection regulations.

1. Limited Current Capacity: The contact rating of 10A may not be sufficient for high-current applications.

2. Requires External Coil: The relay does not come with an integrated coil, which means you will need to purchase it separately.

3. Not Suitable for High-voltage Applications: The relay is designed for low-voltage applications and is not suitable for high-voltage applications.

In conclusion, the Telemecanique DK22F7 is a reliable and compact latching relay suitable for various industrial applications where a contact needs to remain in its position after the power is turned off. However, it may not be suitable for high-current or high-voltage applications. If you require a relay for high-current or high-voltage applications, you may want to consider other options with higher contact ratings and integrated coils.

Based on the information provided, I would recommend the Telemecanique DK22F7 for applications where a latching relay with a compact size and a contact rating of 10A is required. However, it's essential to ensure that the application does not exceed the relay's current capacity and that an external coil is available if needed.
