Product Description

SRA24VDCCL 5-Pin Power Relay

High-Current SPDT Relay for Arduino & Automation

The SRA24VDCCL is a highperformance 5pin power relay designed for switching heavy loads with a low-power control signal [citation:1][citation:3]. Featuring a 24V DC coil and SPDT (Single Pole Double Throw) contacts, this relay is ideal for Arduino, ESP32, and industrial automation projects requiring reliable load switching.

24V DC coil with 600mW power consumption
SPDT contacts with 20A switching capacity at 14V DC
Maximum switching voltage: 125V AC - do not exceed

NO = disconnected when relay OFF, connects when relay ON

Wiring Guide

# Coil Control

  • Pin 1 (Coil +): Connect to 24V 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 Arduino [citation:2]
For inductive loads, use RC snubber circuit to suppress arcs
Maximum switching voltage is 125V AC - do not use for 240V mains [citation:11]

Arduino Test Code

#define RELAY_PIN 8

void setup() {

pinMode(RELAY_PIN, OUTPUT);

digitalWrite(RELAY_PIN, LOW);

}

void loop() {

digitalWrite(RELAY_PIN, HIGH); // Relay ON

delay(2000);

digitalWrite(RELAY_PIN, LOW); // Relay OFF

delay(2000);

}

Use MOSFET or transistor driver for reliable switching

Add flyback diode to prevent voltage spikes
Do not connect relay coil directly to Arduino pin - insufficient current
