@terxw okey, thanks for reporting back !! Let me know if there is something else. This is a 0.5v so I'm open for improvements.

The choice of MOSFET can be tricky. Seems that irlz44n was discontinued so you may need to find one adapted to the voltage and current you want to handle. In all the cases you need to get a logic MOSFET too, meaning that they are fully open usually around 1 to 3V. Also I'm sort of confused as it seems to me that L7812CV is a Voltage regulator, not a MOSFET. So if you are actually using that in the MOSFET spot it will definitively not work. Especially if you are handling high current or voltage I would recommend using one from a reputable source for your MOSFET, I recently switched from mouser / digikey / aliexpress to mostly use http://www.arrow.com as you get free regular shipping, event if you order a couple of components (no affiliation to them whatsoever).

@kimot I am not handling that situation. I'm taking for granted ssr will do his job. Maybe there's some ssr safety topic I'm unaware? Suggestions for a v3.0 are welcome. About the temperature measuring... I use two sensors. The one in the board protects electronics from temperatures beyond design (60°C). It's near the ssr because the ssr's derating curve is the most limiting condition. The control sensor is placed in the bottom of the heater. It connects to the board through a 3 pin header connector.

@sparky60 yes, 4 inputs and 4 outputs. It should be easy to modify if you need a different amount.
