PEC autostart control circuit

[ming125]

Hi
Could anyone advise me on a PEC autostart control circuit.
Basically I have two conveyors(3 Ph sc motors) Once manually started I need them to stop, start according to the PEC's requirment,stop when the beam is broken and start when the object is removed from the beam and stop completely if an e stop is pressed.

Thanks

I'd be tempted to use a "smart relay". Lots of manufacturers sell almost identical products (Telemechanique is one that springs to mind), and they're a doddle to use. They just apply a bit of logic to some inputs and give you the output (on/off) that you need. I've used them for various alarm circuits and they were easy peasy. They could be programmed from a PC (and simulated on one) and all in, including software, only cost about £100.

Sorry for the delay.
Try RS Components. There're a few to try. Telemechanique Zelio controller is one that springs to mind, but I think other manufacturers make almost identical bits of kit. The Zelio used to come as a starter pack with serial cable and software at a good price, but I've not checked the latest catalogue
