Songle Power 24VDC Relay SRU-24VDC-SL-C PCB 5 Pin

📌 Product Overview

The Songle Power 24VDC Relay (SRU-24VDC-SL-C) is a reliable electromagnetic switching component designed to enable a low-power 24V DC control signal to switch higher voltage and current loads. It’s commonly used in industrial control circuits, automation systems, embedded designs, and electronic switching applications.

🔹 Key Features

• Model: SRU-24VDC-SL-C

• Coil Voltage: 24V DC

• Contact Type: SPDT (Single Pole, Double Throw)

• Total Pins: 5 (through-hole PCB mount)

• High Switching Capacity: Up to 10A

• Compact & Durable Housing

• Standard Footprint for PCB Assembly

🛠 Technical Specifications

🔹 Pin Configuration (5-Pin Layout)

1. Two pins: Coil input (24V DC)

2. Three pins: Output switching contacts

   • COM (Common)

   • NO (Normally Open)

   • NC (Normally Closed)

➡ When 24V DC is applied to the coil, the relay switches from NC to NO.

📌 Applications

• Industrial control systems

• Motor and actuator switching

• PLC & automation circuits

• Home appliances

• HVAC controls

• Alarm and security systems

• Robotics & embedded designs

• Power distribution projects

🔹 Advantages

✔ High reliability and durability
✔ Good mechanical and electrical isolation
✔ Suitable for controlling heavy loads
✔ Easy to interface with microcontrollers, sensors, and PLCs
✔ PCB-mountable for compact designs

📦 Package Includes

• 1 × Songle Power 24VDC Relay (SRU-24VDC-SL-C)

🔧 Note / Tip

To ensure reliable switching and long life, always pair the relay with an appropriate flyback diode (for inductive loads) and follow recommended PCB layout practices.
