Seeed Studio Latching Relay Module, Arduino Board - 103020010

Features Energy efficiency: Coils do not need to be energised all the time, helping to reduce power consumption in application circuits Dual Switch: Single side stable and latching type available. Grove unified socket: The product ensures "Plug and Play" and could be versatile for various applications. High sensitive: Up to 150mW High switching capacity: 125VA/90W Description This module is based on 2-Coil Latching Relay. Contrast to the ordinary relay, this latching relay does not need continuous power to keep the state, only a rising/falling pulse is needed to change the work state. Even the power can be removed when the work state does not need to change, making this module especially suitable for low-power projects. We have developed more than 400 Grove modules, covering a wide range of applications that can fulfill various needs. Click to explore the Grove Sensor family and get started to Grove your Idea. For all Grove users (especially beginners), we provide you with guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your use of the product. What are latching relays Relays are common electromechanical devices in circuits and come in two types: latching or non-latching. Latching relays retain their last switching position even after a complete power failure, whether single or dual coil types. Single-coil latching relays use only one coil to set or reset the switch position, but require both positive and negative voltages. When a positive voltage is applied, current flows in one direction and puts the relay into the set state (i.e. the relay switch is closed). If a negative voltage is applied, it reverses the direction of current flow and puts the relay into the reset state (i.e. the switch is open). A dual coil latching relay, on the other hand, uses only a positive voltage but requires two power supplies or drivers. This type of relay has a set coil and a reset coil. When the set coil is energised, the relay enters the set state. Conversely, when the reset coil is energised, the relay enters the reset state. However, both coils are never energised at the same time.
