Power Relays, Over 2 Amps: JC1A-DC12V Application Field and Working Principle

Power relays are used as the main interface between an electrical circuitry and a device. Relays are used to control electrical circuits from a distance, without requiring a direct connection. The function of some of the most powerful current-carrying relays of over 2 Amps is to provide electrical isolation between the input and output circuits.This article will focus on JC1A-DC12V, a relay designed and manufactured by Song Chuan, a Taiwan-based company. It is an ultra-miniature surface mount relay. The product boasts a switching capacity of up to 10 amps, 12VDC. It can be surface mounted and has long creepage and clearance distances, providing excellent electrical isolation.

Overview of JC1A-DC12V

The JC1A-DC12V is a 12 volt DC rated relay designed to be used in low-power applications. It can be used in a variety of fields, such as for insulation, switching, and motor control in industrial, automotive, and consumer products. Its switching capacity is up to 10 amps, and its contact configuration is SPST-NO (Single Pole Single Throw – normally open). Its contact rating is 3A/120VAC and 8A/24VDC. The contact material is silver (Ag), and the contact arrangement is 1NC, 1NO (1 Normally Closed, 1 Normally Open). The maximum switching power is 240W. It is UL and CUL listed.

Working Principle

The working principle of a relay is based on electromagnetism. It uses a solenoid, a coil, and an armature to move a contact from one position to another. When an electric current is passed through the solenoid, a magnetic field is created, which attracts the armature, causing the relay switch to close/open. The JC1A-DC12V relay is operated in exactly the same way.First, an electrical current is passed through its input terminal. The input current is then increased to a high level, generally 7-10 times the normal current level. This creates a strong magnetic field, which magnetizes the coils of the JC1A-DC12V. This magnetized field then attracts the armature, which causes the contact to close/open. When the armature is attracted, the contact closes/opens and the current from the input terminal is transferred to the output terminal.The JC1A-DC12V is a reliable and effective solution for power switching applications with a current rating of up to 10 amps, 12VDC. Its contact configuration, contact rating, and contact arrangement make it suitable for a wide variety of applications. Its long creepage and clearance distances ensure excellent electrical isolation of the input and output circuits, protecting the connected equipment from potential damage due to faulty connections.
