4 CHANNEL SOLID STATE RELAY MODULE

Description

The Whadda four-channel Solid State Relay (SSR) module can be used to quickly and efficiently switch AC loads on and off without using any moving parts (e.g. like a classic electromechanical relay).

The SSR module uses a phototriac to provide a galvanic isolation between the logic level side and the AC load side. All four of the channels can be switched on by providing a HIGH logic level signal (3 – 5 V), and off by providing a LOW logic level signal (0 – 1,5 V) to its corresponding channel signal input.

Note that this module can ONLY SWITCH AC CURRENTS, up to a maximum of 2 A, with a maximum voltage of 240 V AC. Trying to use this module to switch DC loads or exceeding the specified limits can damage the module and/or your connected devices!

Features

• Safe switching without moving parts: This module uses optocoupler technology, which means there are no moving parts that can wear out or cause malfunctions. This allows you to switch your electrical devices reliably without the concerns of mechanical wear.
• Optimal galvanic isolation: The built-in optocoupler ensures safe galvanic isolation between the low voltage signal and the AC high voltage side. This minimizes the risk of electrical interference and protects your switching logic from high voltage issues.
• Suitable for AC applications: With a maximum load voltage of up to 240 VAC and a current rating of 2 A, this module is suitable for high-power AC applications. This allows you to switch heavier electrical devices and loads with confidence and precision.
• STEM project: Develop and improve your STEM skills and acquire the knowledge, skills and experience needed to face the technological challenges of the future with this educational kit. This educational kit will trigger a number of processes such as problem-solving, investigative and creative thinking.
• Made in Belgium : Whadda is a unique brand from Belgium’s Velleman Group that offers DIY projects for hobbyists or makers who want to immerse themselves in electronics, programming and mechanics.
