A normally closed relay will switch power off for a. There are 2 types of 4 pin relay available.
Difference Between 4 Pin And 5 Pin Relays
Standard 4 pin relay. 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. Maximum ac load current. When the relay is not activated the common pin is in contact with the nc pin and when it is activated the common pin will break away from contact with the nc pin and subsequently makes contact with the no pin. Features of 5 pin 5v relay. Circuitry is designed to withstand electr. 300 operatingminute mechanically equivalent relays.
Measurements 22 d x 15 w x 25 h. 10a at 3028v dc. 4 pin 24volt diode protected 10amp micro relay. Trigger current nominal current. A normally open relay will switch power on for a circuit when the coil is activated. The 95mm wide terminals tend to be used for higher power applications such as for starter motor solenoid activation and the smaller terminals tend to be used for electronics signalling where only very low currents are required.
How to use a relay. Trigger voltage voltage across coil. Ii single pole double throw spst such relay has 5 terminal pins which consists of a pair of coil pins a common pin a normally open no pin and a normally closed nc pin. Relay has 2 x 48mm male terminals and 2 x 635mm male terminals. Also when the relay is deactivated from activated state the common pin will conversely break away. 3v relay 12v relay 1 channel relay module 4 channel relay module.
All widths will be compatible with the standard female blade crimp terminals of the corresponding. Relays are most commonly used. Copper terminals with aluminum inlay keep electrical resistance low and still provide benefits for wire bonding and corrosion protection. The terminal widths used on 4 and 5 pin relays are almost always 63mm wide however some more specialist relays can have terminal widths of 28mm 48mm and 95mm. 10a at 250125v ac. Compact 5 pin configuration with plastic moulding.
Normally open or normally closed. Maximum dc load current.
