Very good video brother. Thank you for sharing. I also use contactor on upstream of the SSR, and this is connected to the alarm contact in the PID temp controller. If the SSR triac fails closed, the temperature will overshoot the SV, and the alarm function will open the contactor cutting power to the SSR and the heater.
I was going to add this. I've used SSRs in ceramic kilns. When they over heat, they are derated to less than 20% of their stated capacity and will often fail closed. This means, for any substantial heating capability, a contactor must be placed on the alarm or a secondary PID to allow for alarm like operation for over SV condistions.
Electronic control of tankless water heater: Use a PID? SSR vs SCR? I have an 8KW Atmor tankless water heater that has two switched heating elements. I want to add stable electronic temperature control. But I can't find good information about the different options! Seems the PID + SSR MAY have longer switching time, and that MAY reduce heating element life from thermal cycling vs a higher speed SCR. But I am having trouble finding the real answer.
I have experience with ssr&heaters,if the heater is short body the ssr usually damage (the load contact always close like problem in the mech.relay)although the ssr have bigger amperage than CB..what do you think?
SSR Comes with in build fuse, and blow if any short circuit from heater side . But here we can also face problem, fuse blown time is 20ms and triac short circuit time is 100us, so fuse benefit is less

Thank, how could you protect the circuit if the ssr break and the heater keep receiving energy even if the thermocouple is on temperature
Thank you very much
Thank you sir
Can iuse 1.5 hp motor CSCR motor.on 40amps SSR DA
