Enhance your electronic control projects with this high-performance DPDT Relay Module featuring a self-locking (bistable) double-pole double-throw design. Engineered for stable and reliable operation, this relay module offers efficient control with built-in safety and convenience features. Ideal for applications requiring low power consumption and precise switching, it supports motor loads up to 3A and is easy to install and operate. Key Features: · **Self-Locking Bistable Relay:** The double-pole double-throw (DPDT) relay switches states with each trigger pulse — once activated, it remains engaged until triggered again to disconnect, enabling reliable latching control. · **Dual Voltage Options:** Available in DC 5V and DC 6-24V versions, allowing flexibility to suit different power supply requirements. · **Low Pulse Control Mode:** Designed for safe operation using low pulse trigger signals (0.2-2 seconds low pulse), minimizing power consumption and enhancing device longevity. · **Power and Reverse Polarity Indicators:** Equipped with LED indicators to display power status and reverse polarity alerts for easy monitoring and error prevention. · **High Load Capacity:** Supports a maximum load current of 5A, with motor loads recommended up to 3A, suitable for various electronic devices and automation projects. · **Compact and Easy Installation:** Measuring approximately 39.5 x 33.3 x 23.3mm, this relay module is compact, lightweight, and designed with clearly labeled pins for straightforward wiring and integration. · **Stable and Reliable Components:** Manufactured using high-quality electronic components ensuring long-lasting performance and durability under continuous use. Specifications: · Item Type: DPDT Relay Module · Input Voltage: DC 5V (5V version) or DC 6-24V (12V version) · Module Working Current: Forward 2mA, Reverse 60-70mA · Load Current: Maximum 5A (motor load ≤ 3A) · Control Mode: Low pulse control (0.2-2 seconds low pulse) · Size: Approx. 39.5 x 33.3 x 23.3 mm (1.6 x 1.3 x 0.9 in) Pin Description: · V: Power positive terminal · G: Power negative terminal & trigger ground · T: Trigger signal input · NO1 / NO2: Normally open contacts · COM1 / COM2: Common contacts · NC1 / NC2: Normally closed contacts Operation Instructions: When powered on, the relay is initially off. Applying a low pulse to the trigger input (T) activates the relay, pulling it in. Sending another pulse releases the relay, providing bistable switching control suitable for a variety of electronic and automation projects. Package Includes: · 1 x DPDT Relay Module This DPDT Relay Module offers a reliable, energy-efficient switching solution with clear indicators and versatile voltage compatibility. It is an essential component for hobbyists, engineers, and professionals working on motor control, robotics, and smart home automation systems.
