5-pin SRD relay refers to a type of electromechanical relay that typically has a 5-pin configuration and is often used in low- to moderate-power switching applications. SRD is the model code for a common type of relay used in various devices, such as microcontrollers, home automation systems, and industrial controls.
Voltage: 3V
Pins: 5 pin
Color: blue
Product Size:(L*W*H) 1.89*1.50*2.00cm/0.74"*0.59"*0.79" (Approx.)
Pin Configuration:
The 5 pins on an SRD relay are typically arranged as follows:
Pin 1: Coil (A) – One terminal of the coil (input side).
Pin 2: Coil (B) – The other terminal of the coil.
Pin 3: Common (COM) – The common terminal that connects to either NO or NC.
Pin 4: Normally Open (NO) – This contact closes when the relay is activated (energized).
Pin 5: Normally Closed (NC) – This contact is closed when the relay is not activated (de-energized), and opens when the relay is energized..
