Is this Electronics-Salon relay module safe for Arduino and Raspberry-Pi projects?

Yes, this Electronics-Salon 2 DPDT Signal Relay Module is designed for use with microcontrollers like Arduino and Raspberry-Pi. It operates on a 24V DC coil voltage and uses low-level control signals, preventing damage to your sensitive project electronics. Always ensure your power supply matches the 24V DC requirement and that control signals are within the specified range.

What is the contact rating for this 2 DPDT relay module?

Each switch on this 2 DPDT relay module can handle a maximum rating of 120VAC at 0.5 Amp or 24VDC at 1.0 Amp. This makes it suitable for switching low-power AC signals or DC loads within these limits, but not for high-power applications.

Can I use this 24V DC relay module with Indian mains power?

No, you cannot directly connect this 24V DC relay module's coil to Indian mains power (230V AC). The coil requires a specific 24V DC supply. You will need a compatible 24V DC power adapter or a step-down transformer to safely power the relay coil from the mains.

How do I connect signals to this relay module?

Connect your control signal (e.g., from an Arduino digital pin) to the 'IN-X' terminals, ensuring it's between 2.5V-24V DC for activation. The relay's common, normally open (NO), and normally closed (NC) contacts are connected via the high-quality screw terminal blocks for your load circuit.

What does DPDT mean for this relay module?

DPDT stands for Double Pole Double Throw. This means each of the two relays on the module has two independent sets of contacts (poles), and each set can switch between two circuits (throws) – typically a normally open (NO) and a normally closed (NC) position. This allows for more complex switching configurations.

How to choose the right relay module for my project?

Consider the required coil voltage (e.g., 5V, 12V, 24V DC), the type of contacts needed (SPST, SPDT, DPDT), and the maximum current and voltage the contacts must switch. Ensure compatibility with your microcontroller's output signal levels and power supply.

Are there any side effects of using this relay module?

When used correctly within its specified voltage and current limits, this relay module has no negative side effects on your project electronics. Ensure proper wiring and power supply to avoid damage. It provides electrical isolation between the control circuit and the switched load.

About this item

The Electronics-Salon 2 DPDT Signal Relay Module (DC 24V) offers reliable signal switching for your Arduino and Raspberry-Pi projects. It utilizes high-quality TAKAMISAWA RY24W-K relays with gold overlay silver-palladium contact material, ensuring durability and performance. The module is driven by Darlington transistor circuits, includes LED indicators for each relay channel, and features a high-quality screw terminal block for easy connections. Its FR-4 fiber glass PCB with dual copper layers provides a robust foundation.

This module operates on a VCC of 16.8 to 31.2VDC, drawing approximately 40mA at 24VDC. The control signal voltage (IN-X) requires a high level of 2.5V to 24Vdc for relay activation, while a low level of 0V to 0.5Vdc keeps the relay inactive. Each switch offers a contact rating of 120VAC at 0.5 Amp or 24VDC at 1.0 Amp, suitable for various signal control applications.

While this module is designed for precise signal control, local alternatives may offer different contact materials or voltage handling. This imported unit ensures authentic performance for your critical circuits. All customs duties and GST are included in your price, with delivery via ExpressBox tracked shipping.

Why choose this product

Precision Signal Control for Projects

This module offers precise control for your Arduino, Raspberry-Pi, or other microcontroller projects. The gold overlay silver-palladium contacts ensure clean signal transmission, minimizing signal loss or degradation. Unlike basic relays, its DPDT configuration allows for more intricate circuit management. It's designed for applications where reliable switching of low-voltage signals is paramount, ensuring your automation or control systems function as intended without interference.

Ideal for 24V DC Control Systems

This relay is specifically designed for 24V DC control circuits, common in industrial automation and hobbyist projects using microcontrollers. It's best suited for users who need to switch signals up to 120VAC/0.5A or 24VDC/1.0A. Those requiring higher current handling or AC coil operation should look for different models. If your project involves sensitive signal routing or requires precise switching in a 24V DC environment, this module is a strong choice.

How to use

Connect a stable 24V DC power supply to the VCC and GND terminals of the module. Ensure the supply can provide at least 40mA to handle both relays activating simultaneously. — Connect Power Supply
Connect your microcontroller's digital output pins (e.g., from Arduino or Raspberry Pi) to the IN-1 and IN-2 terminals for each relay. Ensure the output voltage is within the 2.5V-24V DC range for activation. — Connect Control Signals
Connect your load (e.g., pump, LED, motor) to the relay's output terminals (Common, NO, NC). For a 24V DC load, use the 24VDC/1.0A rating. For AC loads, use the 120VAC/0.5A rating. — Wire Load Circuits
Apply power to the module and send high-level control signals from your microcontroller. Observe the LED indicators and verify that the connected loads are switching correctly according to your circuit design. — Test Operation
