Dear all,
I am facing an awkward problem with temperature control using Siemens S7-300 PLC. Now, the problem is that I want to control the temperature of the tank using PWM output from PLC to heater through solid state relay. Now, the problem is that I don't have the rating of the heater. So, if I want to use SSR to control the PWM to heater, how can I determine the rating of SSR if the heater's rating itself is unknown?
P.S. : Heater operates on 230 v AC supply.
Regards,
