jOY-it SBC-SSR01, 4-Channel Solid State Relay, Galvanic Isolation

jOY-it SBC-SSR01 – 4-Channel Solid State Relay with Galvanic Isolation

The jOY-it SBC-SSR01 is a compact 4-channel solid state relay module with galvanic isolation. It enables safe switching of loads up to 240 V AC and is ideal for use with microcontrollers and single-board computers like Raspberry Pi or Arduino.

• Four independent switching channels for separate control of multiple loads – for flexible automation solutions
• Galvanic isolation reliably protects the control electronics from voltage spikes and interference
• Switching voltage up to 240 V allows control of household appliances, lights and motors
• Compact form factor fits directly on a breadboard or into an enclosure – ideal for development projects
• Simple control via GPIO pins – compatible with 3.3 V and 5 V logic

What sets the SBC-SSR01 apart

Unlike mechanical relays, the solid state relay operates completely silently and without wear. The galvanic isolation ensures reliable isolation between the control and load circuits. The module is optimized for easy connection to single-board computers.

Ideal for...

Developers, makers and electronics hobbyists who need a reliable way to switch AC loads with digital signals. The module is particularly suitable for smart home projects, home automation, laboratory applications and switchable power supplies.

How to use the SBC-SSR01

Connect the control pins of the module to the GPIO pins of your microcontroller. Apply the load voltage to be switched to the switching terminals. The control level (HIGH) activates the channel. Observe the maximum switching voltage of 240 V and the load current (see data sheet). The module does not require a separate supply voltage for the control side – the logic levels are supplied directly by the GPIOs.
