I know that you should not use a non-safety rated PLC for safety applications, but I was wondering if anyone saw anything wrong with the application that I am looking at. I have machine which has four different sections that can be started independently of each other. I need to install flicker lights and warning buzzers to indicate when a section is about to start. Would it be acceptable to use a small PLC to do this versus using real world timers and relays or a safety rated PLC. The PLC will do nothing more than create a three second delay while the start PB is pressed before the section will start. It will also sound a warning buzzer and flash a warning light during this three seconds. In no way will it be tied to the e-stop circuit.
