4 Channel Solid State Relay
4-Channel Solid-State Relay is somewhat similar to that of a mechanical relay & the difference is that there is no moving contact in a Solid-State Relay.
Here we make use of a Phototrriac coupler to turn it ON and OFF. It finds its application in AC circuits as a TRIAC has got only limited applications in DC.
This module is ideally suited to controlling larger voltages with the project. This is a 4 channel relay module that can be used to activate up to 240V AC.
This allows you to build in device control, operating lighting, or triggering systems when the module is triggered. With the labeled screw terminals it's easy to connect.
Solid State Relay - Solid State Relay (SSR) has advantages such as more efficient switching speeds, more stable operation against electrical noise, longer service life, resistance to physical vibrations and resistance to moisture, which distinguish this type of relay from ordinary mechanical relays.
These relays are preferred in places that require fast and precise operation such as computer peripherals, medical devices.
Solid-state relays do have several advantages over mechanical relays. One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays.
Also, because there are no moving contacts, solid-state relays can be switched much faster and for much longer periods without wearing out. This is a quad-channel relay module which can be used to activate up to four separate 240V AC.
This allows you to build in device control, operating remote lights or triggering systems when the module is supplied the signal.The screw terminals are well labeled and definition of the units function is shown underneath.
Also, read our blog on What is a Relay detailing how it works, relay contact types, and different types of relays and their application.

1. What is a solid-state relay used for?
- A solid-state relay (SSR) is an electrical switch that can be used to turn things on and off using another electrical input. Unlike electromechanical relays (EMRs), semiconductor switches and optoelectronics are used in SSRs instead of magnetism and moving contacts.
2. Are solid-state relays more reliable?
- A solid-state relay has a longer electrical and mechanical lifetime compared to a mechanical relay. The time in the operation of an SSR determines its reliability, not the number of switching cycles.
3. How fast can solid-state relays switch?
- Solid-state relays can switch up to 120 times per second, much faster than any electromechanical relay. When used in heating applications, fast cycling can significantly improve heater life by reducing thermal stress. SSRs can switch large loads using the ultra-sensitive input power.
4. What is the difference between Solid-state Relays and Contact Relays?
- Solid State Relays use semiconductors for no-contact operation. In operation, Solid-state Relays are similar to Contact Relays (Electromagnetic Relays). Solid-state Relays, on the other hand, are made up of electronic components with no mechanical contacts. As a result, Solid-state Relays have a number of features that Contact Relays do not have.
