I have a series of stacklites I want to use to provide takt time feedback to operators on a production line. Each stacklite has a red, green, and amber light (120V AC) as well as a buzzer.
I am looking to have an LED display show a countdown of the available cycle time (1 hr) and trigger the change in lights from green to yellow at a programmable time (15 mins remaining) and the buzzer to sound at the completion of the time.
Each operator will have a pull cord switch to activate the red light if a problem occurs.
Any suggestions on a product (programmable LED Display with relays?) that could provide these control functions?
Thanks - Jim
