This module is a bi-directional SPSD(single-pole, single-throw), normally open solid state relay(SSR).

This module is a bi-directional SPSD (single-pole, single-throw), normally open solid-state relay (SSR). The Grove Optocoupler Relay is based on M281. This device offers very low on-resistance-allowing for a high load current rating in a miniature package, ideal in higher power applications where board space is limited.

Unlike the other TRIAC SSR in our website, this relay is based on MOSFET, so it can carry both AC load and DC load. If you need to use a SSR with the DC load, this is what you want!

Tip

We've released the Seeed Relay Selection Guide, it will help you choose the relay that best suits your needs.

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.
