Our TVS devices are designed to protect sensitive electronics from damage or latch-up due to ESD, lightning, and other voltage-induced transient events. Dec 2, 2020 #11 Search online for a 3.3v relay module . But as will discussed below this is not the case for 12V relay modules. It can also be used to drive different voltages relays with 3V DC. Since both the Arduino drive voltage and the relay coil voltage is the same, +5V, there is no problem with low triggered inputs since the voltage from the relay board being pulled down by the digital output will not be more the 5V. Dec 2, 2020 #12 Wilmer Kluever said: I used this one: SSR-100DA. Standard (B.B.M.) Types of Relays TYPES 1. type 2) Surface-mount terminal 2. Such as 12v, 24V, or mains voltage ( 220V or 240V).
