Hi, I'm looking for a function block for the following. Input: Set Value in °C Input: Actual Value in °C (measured by a PT1000 sensor) Output: Digital output that controls a Solid State Relay.
Application: Controlling the temperature of a welding bar as precise as possible.
Who can help me?
I allready looked at PID solutions, but they all put out a analog value.
Thanks for the help.
You can use PWM for this purpose. Assume that you have 0 to 500 unit analog PID output. Convert this value to percentage and use it as ON time.
Hi, thanks for the answer. It's a good idea, I will work it out and let you know the outcome.
