What is an 8 pin relay used for?
They are often used to interface an electronic circuit, which works at a low voltage to an electrical circuit which works at a high voltage.
What are the pin numbers on a relay?
Numbers of a Relay 85 and 86 are the coil pins while 30, 87, and 87a are the switch pins. 87 and 87a are the two contacts to which 30 will connect. If the coil is not activated, 30 will always be connected to 87a.
How do you test an 8-pin relay?
If you want to check the relay coil’s resistance, place the multimeter on the 2 terminals of the relay’s coil and use the probe leads of the multimeter. It doesn’t matter what probe is placed on which terminal.
Why would you use a 5 pin 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.

How many terminal pins are in a DPDT relay?
Such relay is actually a combination of two SPST relay structures with only one coil pin pair. iv) Double Pole Double Throw (DPDT) – Such relay has 8 terminal pins which consist of a pair of coil pins, two 3 pins group for each group consists of a common pin, normally open (NO) pin and normally (NC) pin.
How do you plug a relay into a DIN rail?
Attach quick-disconnect terminals or plug these relays into relay sockets. Also known as ice cube relays. Relay sockets (sold separately) mount to 35 mm DIN rail or flat surfaces. Ht. Wd. Dp. Tab Wd. Thinner than other spade-terminal relays, these fit in tight spaces. Attach quick-disconnect terminals or plug relays into relay sockets.
What kind of relay socket do I need for 750-3c?
Relay socket for 750-3C, H750-3C and 755 series octal relays, 11-pin relay socket configuration, 35mm DIN-rail or panel mount
