5v to 24vdc pulse converter

Hello,
I had to wire up a 5Vdc encoder to a Fanuc robot. Originally was supposed to be 24Vdc until we found out fanuc couldn't handle it. Now my plans to steal the C (Z) pulse are in tatters. Was just going to wire in parallel.
Without re inventing the electronics market, does any one have some info for getting the C (once per revolution) pulse at 5Vdc into my PLC at 24Vdc S7-200.
Ideally I suppose the circuit should be a pulse in and a timed out then I would't miss it but just getting it first would be nice.

I dont like Fanuc much but can you not get an output from the robot for revolutions ?

Good idea, But the robot software is event driven no interrupts so could miss a pulse. You can buy background task software but very expensive.

Check out the Optical Isolator Module here. We've used it in incompatible situations before.

Depending on the frequency, you could also just use a SSR.

Bernie,

thanks for the link
