4 Channel DC 5V Solid State SSR Relay Module

Product Description

The Omron 5V Solid State Relay Module is a compact switching module designed to control AC loads up to 240 V and 2 A using a low-voltage 5 V DC control signal. It uses a solid-state relay for electronic switching without the mechanical contacts found in conventional relays, making it suitable for applications requiring frequent switching.

The module features a low-level trigger input, where a signal between 0–1.5 V turns the relay ON, while a 2.5–5 V signal turns it OFF. It operates from a 5 V DC supply and has a compact size of approximately 56.6 × 55.4 × 24 mm.

An onboard 240 V 2 A resistive fuse provides additional protection for suitable loads. The module is suitable for automation, Arduino projects, embedded systems, and AC load switching applications.

Working Principle

The module uses a solid-state relay to electronically switch an AC load based on the input control signal. When the trigger input is at a low level of 0–1.5 V, the relay switches ON and allows the connected AC load to operate.

When the input signal is raised to 2.5–5 V, the relay switches OFF and disconnects the load. The solid-state design provides electronic switching without mechanical contacts.

Product Disclaimer

This module is designed for AC load switching only according to its specified output ratings. Do not exceed the stated 240 V AC / 2 A output rating. Actual load capacity depends on load type, temperature, wiring, and operating conditions.

Working with mains voltage can cause electric shock, fire, or serious injury. Proper insulation, enclosure, wiring, and safety precautions must be used. Installation and mains-voltage connections should be performed by a qualified person.

The stated fuse rating is intended for suitable resistive loads and does not guarantee protection for every type of load.
