Hi All,
I have to control a heating system using siemens s7-1200 PLC. The heating system can be controlled by switching it's power on/off. The rating of the system is 230V AC, 2000W. Therefore I need a suitable optocoupler to interface PLC with the heating system. I have a plan to implement hysteresis type control. Sometimes, I might be needed a fast switching optocoupler if I use PWM output (0-10 VDC ) of PLC(PID control) to control the system.
How to choose a suitable optocoupler for my application? Please give some information model to select the suitable optocoupler from TI products.
Thank you.
Kind regards,
