Specs of Power Relay FeatherWing

by MatthewKyeo on Thu Sep 12, 2019 2:31 pm

PRODUCT ID: 3191
https://www.adafruit.com/product/3191

I’m thinking of using an Arduino DUE’s 3V GPIO to turn on/off the relay.
May I ask
- can this relay be controlled with 3V GPIOs?
- I want to connect a signal from the function generator which generates ± 80V pulse wave (10kHz)
Can this relay accept this signal?
- Can the relay switch handle 10kHz? I cannot check the switching speed of this relay

It can use 3V on the GPIO. If you look at the picture, you'll see that value on the relay itself.

A mechanical relay isn't going to handle 10 KHz switching. The Datasheet says the maz. switching frequency is 18,000 operations per hour which is 5 Hz. You'll want something solid state for 10 KHz.

Your function generator actually puts out ±80 volt pulses??? What are you trying to drive at 10 kHz?

You're going to have to describe more about what you're doing. It's sounding pretty aggressive.
