This is a 12V DC SPDT type Relay. it can be used to switch AC 250V upto 7A. 5 Pin relay is also called suger Cube Relay. This is PCB mount type relay. JQC-3FC(T73)DC12V, 50/60Hz, 7A 250V AC, 12A 120V AC.

How a relay works?

Relays are switches that open and close circuits electromechanically or electronically. Relays control one electrical circuit by opening and closing contacts in another circuit. When a relay contact is Normally Closed (NC), there is a closed contact when the relay is not energized.

What is JQC3FC?

These are high-quality Single Pole – Double Throw (SPDT) sealed 5V Sugar Cube relays. Use them to switch high voltage (240AC), and/or high current devices(7A). For Bulk Orders contact us on [email protected] Features 5V DC SPDT Relay Rated up to 7A @240VAC Fully Sealed. Model No. : JQC3FC 7A 12V.

How does a 4 pin relay work?

4 Pin Relay 4 pin relays use 2 pins (85 & 86) to control the coil and 2 pins (30 & 87) which switch power on a single circuit. There are 2 types of 4 pin relay available; normally open or normally closed. A normally open relay will switch power ON for a circuit when the coil is activated.

How many pins are in a relay module?

Relay Basics Typically the relay has 5 pins, three of them are high voltage terminals (NC, COM, and NO) that connect to the device you want to control. The mains electricity enters the relay at the common (COM) terminal. While use of NC & NO terminals depends upon whether you want to turn the device ON or OFF.

Are all 4 pin relays the same?

The problem is, not all relays are the same. Many relays, if installed for the wrong application, could and will cause a short (Internal Relay Circuit) and most likely cause functionality issues or even damage to the vehicle computer systems.

What are the pins of a relay?

A normally open relay will switch power ON for a circuit when the coil is activated. A normally closed relay will switch power OFF for a circuit when the coil is activated. 5 pin relays provide 2 pins (85 & 86) to control the coil and 3 pins (30, 87 & 87A) which switch power between two circuits.

Which pin is ground on a relay?

Realizing that 85 and 86 are the coil pins, these pins will be transferring the current through the coil. 85 will be used to ground your relay, while 86 will be connected to the switchable power.
