= 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 . 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

= Pin Configuration (5-Pin) =

Pin	Function	Description
1	Coil (+)	Positive coil terminal (24V)
2	Coil (-)	Negative coil terminal (GND)
3	COM	Common terminal
4	NC	Normally Closed (connected to COM when relay off)
5	NO	Normally Open (connected to COM when relay on)

Coil is nonpolarized no polarity distinction required

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 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

For inductive loads, use RC snubber circuit to suppress arcs

Maximum switching voltage is 125V AC - do not use for 240V mains

= 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

= Safety Precautions =

Do not exceed 125V AC switching voltage

Ensure load current does not exceed 10A rating

Use flyback diode for inductive loads

Protect from moisture and dust

Keep away from strong magnetic fields

Verify correct wiring before power-up

For mains voltage applications, consult local safety regulations

Use external fuse protection for high-current loads
