Review JERWICKELI 12vdc 40a 4pins Automotive Relay

The Jerwickeli FLS820-012-1A is a versatile and reliable 12VDC 40A four-pin relay designed for various applications. This device is engineered to handle heavy current loads and can be used to switch high power circuits, making it an ideal choice for automotive, industrial, and home automation projects.

The FLS820-012-1A is a normally open (NO) type relay, meaning that when no voltage is applied to its coil, the contacts are not closed and the circuit is open. When an external voltage is applied to the coil, the contacts are mechanically closed, allowing current to flow through the contacts and complete the circuit. This feature makes it perfect for applications where you need to switch high currents on and off.

This relay has a coil resistance of 350 ohms and a contact rating of 40 amperes. Its four-pin configuration includes a coil voltage pin, a common pin, a normally open pin, and a normally closed pin. The coil voltage pin is designed to accept a 12VDC voltage source, while the common and normally open/normally closed pins are designed to carry the main circuit current.

The contacts on the FLS820-012-1A are silver-plated to ensure good conductivity and long contact life. The relay housing is made of durable and rugged materials, allowing it to withstand harsh environments and heavy usage. The relay also features a built-in diode to protect the coil from inductive kickback voltage.

The Jerwickeli FLS820-012-1A is easy to install and can be controlled using external switches, relays, or electronic controllers. Its compact size, measuring 32mm x 22mm x 11mm, makes it suitable for use in tight spaces. Overall, the FLS820-012-1A is a high-performance and reliable relay that is well-suited for a wide range of applications where heavy current switching is required.

The Jerwickeli FLS820-012-1A is a 12VDC, 40A, 4-pin relay. Relays are electronic switches used to control high power electrical loads with low power signals. Here are some pros and cons of buying this particular relay:

1. High Current Capacity: With a 40A current rating, this relay can handle heavy electrical loads that might be beyond the capacity of a regular switch or relay.

2. Versatile: The 4-pin configuration allows for common, NO (Normally Open), and NC (Normally Closed) configurations, making it suitable for a wide range of applications.

3. Durable: The relay has a robust design with a protective coating, which makes it suitable for industrial environments and harsh operating conditions.

4. Cost-Effective: Compared to other relays with similar specifications, the Jerwickeli FLS820-012-1A is relatively affordable, making it an attractive option for budget-conscious buyers.

1. Size: The relay is larger than some other relays with similar specifications, which might make it less suitable for applications where space is limited.

2. Manual Operation: This relay is not a solid-state relay (SSR), which means it has moving parts and requires physical actuation to switch the relay on or off.

3. Limited Operating Temperature: The relay has a maximum operating temperature of 60 C, which might limit its use in high-temperature environments.

In conclusion, the Jerwickeli FLS820-012-1A is a reliable and cost-effective option for applications that require a high current relay with versatile configurations. However, it may not be suitable for applications where space is limited or where the operating temperature exceeds 60 C. Considering these factors, if your application matches the relay's capabilities, it can be a good choice for your needs.

Details:

Conversion Type Contact Form: The FLS820-012-1A features a conversion-type contact form, allowing for seamless switching between different circuits and electrical connections.
