Automate Low-Power Circuits with Precision
The Electronics-Salon 2 DPDT Signal Relay Module Board provides robust control for your electronic projects. Designed for DC 12V systems, it integrates high-quality TAKAMISAWA RY12W-K relays, known for their gold overlay silver-palladium switch contacts. This ensures excellent conductivity and durability for frequent switching operations. The module is driven by Darlington transistor circuits, featuring individual LED indicators for each relay channel, simplifying status monitoring. Its construction includes a high-quality screw terminal block for secure connections and an FR-4 fiber glass PCB with dual copper layers for enhanced reliability.
This relay module operates within a VCC range of 8.5 to 15.6VDC, consuming approximately 60mA at 12VDC. The control signal input (IN-X) requires a low level (0V - 0.5Vdc) for the relay to remain inactive, and a high level (2.5V - 24Vdc) to activate the relay. Each switch output is rated for 120VAC at 0.5 Amp or 24VDC at 1.0 Amp, making it suitable for a variety of low-power AC and DC switching applications in automation and prototyping.
While this module offers precise control, it's essential to match its 12V DC coil voltage with your control circuit's output. Indian industrial control systems often use 230V AC, necessitating a step-down transformer or a dedicated 12V DC power supply for safe and correct operation. All customs duties and GST are included in the listed price, and delivery is handled via ExpressBox with tracking.
Precision Control for Arduino & Raspberry-Pi
This relay module is engineered for microcontroller projects, offering precise signal switching capabilities. Its 12V DC coil voltage and specific control signal requirements are optimized for platforms like Arduino, Raspberry-Pi, and 8051/PIC microcontrollers, enabling seamless integration into your automation setups. The gold overlay silver-palladium contacts ensure minimal signal loss and high reliability for sensitive applications. Imported directly from authorized US retailers, this module guarantees authenticity and adherence to original specifications, unlike grey-market alternatives.
Ideal for Low-Power Switching, Not for High-Current Loads
This module is best suited for controlling low-power AC (120VAC/0.5A) or DC (24VDC/1.0A) circuits, such as triggering other relays, activating indicator lights, or interfacing with low-power solenoids. It is NOT designed for directly switching high-current loads like motors, heaters, or mains-powered appliances. Users requiring high-current switching should look for industrial-grade relays with higher amperage ratings and appropriate safety certifications.
Typical situations where Electronics-Salon 2 DPDT Signal Relay Module Board DC 12V | For Arduino Raspberry-Pi 8051 PIC helps — illustrative scenarios, not customer reviews.
An electronics hobbyist in Bangalore needs to control a low-power LED strip (12V DC, 0.3A) using an Arduino Uno.
This 2 DPDT relay module can be used. Connect the Arduino's digital output (via a transistor driver if needed for signal level) to the relay's control input and the 12V DC power supply to the relay coil. The LED strip can be switched by the relay's contacts, ensuring the Arduino is protected from the load current.
A maker in Delhi wants to automate a small 24V DC fan (0.4A) using a Raspberry Pi.
This module can switch the 24V DC fan. Connect the Raspberry Pi's GPIO (using a level shifter) to the relay's control input and a separate 12V DC power supply to the relay coil. The fan's power circuit is then switched by the relay contacts, which are rated for up to 1.0A DC.
| Recommended Use | Control of low-power AC/DC circuits, signal routing, automation prototyping, interfacing with microcontrollers. |
| Power Consumption | Approx. 60mA at 12VDC |
| Shelf life after opening | 12 months (category default for electronic components) |
| Contraindications | Not suitable for direct switching of high-current loads (>0.5A AC, >1.0A DC). Coil voltage must match control source (12V DC required). |
