Also when the relay is deactivated from activated state the common pin will conversely break away. Maximum ac load current.

Standard 4 pin relay. How to use a relay. 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. 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. 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. 10a at 3028v dc. 10a at 250125v ac.
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. Copper terminals with aluminum inlay keep electrical resistance low and still provide benefits for wire bonding and corrosion protection. Relay has 2 x 48mm male terminals and 2 x 635mm male terminals. Measurements 22 d x 15 w x 25 h. 3v relay 12v relay 1 channel relay module 4 channel relay module. There are 2 types of 4 pin relay available.
Trigger current nominal current. Trigger voltage voltage across coil. A normally closed relay will switch power off for a. Circuitry is designed to withstand electr. Maximum dc load current. Compact 5 pin configuration with plastic moulding.
A normally open relay will switch power on for a circuit when the coil is activated. 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. All widths will be compatible with the standard female blade crimp terminals of the corresponding. 4 pin 24volt diode protected 10amp micro relay. Features of 5 pin 5v relay. 300 operatingminute mechanically equivalent relays.
Normally open or normally closed. Relays are most commonly used.
