Product Description

SRA05VDCCL 5-Pin Power Relay

High-Current SPDT Relay for Arduino & Automation

The SRA05VDCCL is a highperformance 5pin power relay designed for switching heavy loads with a low-power control signal. Featuring a 5V DC coil and SPDT (Single Pole Double Throw) contacts, this relay is ideal for Arduino, ESP32, and industrial automation projects requiring reliable load switching.

5V DC coil with 200mW power consumption
SPDT contacts with 20A switching capacity at 14V DC
Maximum switching voltage: 125V AC - do not exceed

NC = connected when relay is OFF, disconnects when ON
NO = disconnected when relay OFF, connects when relay ON

Wiring Guide

# Coil Control

  • Pin 1 (Coil +): Connect to 5V DC
  • Pin 2 (Coil -): Connect to GND

# Load Switching

  • COM (Pin 3): Connect to power source
  • NO (Pin 5): Connect to load (energized when relay ON)
  • NC (Pin 4): Connect to load (energized when relay OFF)
Use flyback diode (1N4007) across coil terminals to protect microcontroller
For inductive loads, use RC snubber circuit to suppress arcs
Maximum switching voltage is 125V AC - do not use for 240V mains
