After a bit of advice on connecting the 42EF-D2MPAK-F4 to the limit connector on a Falcon 500.
NB: It’s not actually going to be used to limit the falcon, we are just going to use the falcon limit input as a “virtual canifer” on the output of the sensor. We would use a canifer if we could get a hold of them in Australia.
The Sensor is 12V PNP output. The falcon is pull to ground to activate with a 3.3V internal pullup (I think)
You cant really directly connect a PNP output to input that is expecting a connection to ground.
We could put a solid state relay in between, but we were wondering if this is an easier way? What size resister to ground on the falcon would be needed to make the falcon think the switch is closed ?
Idea.
If we knew the size of this resister than we could create a voltage divider across the output of the sensor. When the sensor is “off” the pull down resister would pull the falcon limit to ground. When the sensor is “on” it’s output would go to 12 volts through the PNP output. Then feed this through a voltage divider so it’s output is 3.3 volts and hopefully the falcon thinks its limit input is not connected to ground.
Would this work?
Also is it legal to connect the limit switch power to the same power the falcon is receiving? If not, could this be made legal through using a fuse between the falcon power source and the sensor power source?
Thanks for any help received.
