S1210-2 JOHNSON CONTROLS Relay Latch Blade

Review JOHNSON CONTROLS Relay Latch Blade Used

The Johnson S1210-2 is a versatile and reliable latching relay with blade contacts, offering an economical solution for various automation applications. This 12V DC coil powered relay features two Form C, Normally Open (NO) contacts, which can be used to switch loads up to 120V AC or 240V AC, 50/60 Hz, or up to 30V DC.

The latching action of this relay ensures that the contacts remain closed after the coil voltage is removed, making it particularly suitable for applications where the contacts need to stay engaged after the control signal is turned off. This also eliminates the need for constant power to the coil, reducing energy consumption and simplifying wiring.

The Johnson S1210-2 relay is constructed with high-quality materials, ensuring durability and long-lasting performance. The contacts are silver-plated for excellent conductivity and resistance to corrosion. The relay's compact size, measuring 1.7 inches long by 1.3 inches wide by 0.6 inches tall, allows for easy integration into various control systems.

The latching action of this relay can be controlled by a momentary push-button switch or a DC control voltage. When using a control voltage, the relay will remain latched in the last position the voltage was applied. This feature allows for greater flexibility and control in automation applications.

The Johnson S1210-2 relay is an essential component for various automation projects, including HVAC systems, security systems, and industrial control applications. Its robust construction, latching action, and ease of use make it a popular choice among engineers and DIY enthusiasts seeking a reliable and cost-effective solution for switching applications.

The Johnson S1210-2 is a latch-blade relay with 12 volt DC coil and 2 form C contacts. Here are some pros and cons that may help you make a decision about purchasing this relay:

1. Latching action: The latch blade feature allows the contacts to remain closed even after the coil voltage is removed. This is useful when you want to maintain a circuit connection until a specific condition is met.

2. Compact size: The Johnson S1210-2 is a small, surface mount relay, making it ideal for applications where space is limited.

3. Durable construction: This relay is designed with a robust, corrosion-resistant housing that can withstand harsh environments.

4. Easy to install: With only two terminals per contact, installation is straightforward and can be completed quickly.

1. Limited current capacity: The Johnson S1210-2 is rated for a maximum contact current of 10 amps. If your application requires higher current, you may need to consider a larger relay.

2. Limited voltage rating: This relay is rated for a maximum voltage of 30 volts DC. If your application requires a higher voltage, you may need to consider a different type of relay.

3. Limited number of contacts: With only 2 contacts, the Johnson S1210-2 may not be suitable for applications requiring multiple switches or relays.

In conclusion, the Johnson S1210-2 is a reliable and compact latch-blade relay that is suitable for applications requiring small DC circuits with a latching action. However, it may not be suitable for applications requiring high current or voltage, or multiple contacts. If your application falls within the relay's specifications, it can be a cost-effective and efficient solution. If not, you may need to consider a different type or size of relay.

Overall recommendation: If you have a small DC circuit with a latching action requirement and limited space, the Johnson S1210-2 relay may be a suitable and cost-effective solution. However, if your application requires higher current, voltage, or multiple contacts, you may need to consider a different type or size of relay.
