Hey everyone! I have a mini manual kiln that currently only has a simple on/off switch and no real temperature control. I want to upgrade it so that I can control the temperature properly, particularly to oxidize stainless steel to create different blue color tones. My kiln operates at 9.2 amps and 120 volts. I'm looking at a specific digital controller and relay setup—will that work for my kiln? Do the specs match? I believe I need a module to turn the kiln on and off, connected to the power source, kiln, and controller, with the temperature probe attached to the controller. Is that right? Am I missing anything?

You definitely want to use a closed-loop heater controller for this! It helps you manage the temperature accurately through PID control and PWM heating, plus it can support multiple thermocouples if needed. Just make sure to check the specs of the controller and relay you're considering to ensure they can handle the power of your kiln!
A relay-based option should definitely work for a heat-generating device like yours. Just make sure it can handle the amperage and voltage of your kiln. If you're unsure, I can help find some visual guides if you’d like!
That would be awesome, could you link me to something? I thought the module I found was a relay.
So the closed-loop controller is exactly what I'm considering? That sounds promising!
