Hello first time posting here!
I'm installing an IR sensor for object detection for an KUKA KRC4 robotic arm.
The first problem is that I thought that the Beckhoff control system would have a analog in but when i got the drawings for the machine it did not have it.
The IR sensor sends out an analog out signal so I have decided to build a comparator to send the signal to beckhoff EL1809 digital in terminal which needs minimum 11 V to get a "1". The IR sensor is attached to a 3D printed box that will be attached to the arm, the box will contain a comparator to signal the digital in terminal.
But now the thing to figure out is how to power both circuits, for the sensor which needs a supply voltage of 4,5 to 5,5 V, and the comparator that can at maximum work at 18 V.
There is a connector on the arm X41 that I think goes to the Beckhoff EL2809 and EL1809 digital terminals.
The X41 connector has 12 ports the first 2 are digital out that i think goes to the EL2809, and 3 to 8 are digital in that goes to EL1809, port 9 is UP_24 V, port 10 is UP_0 V, and the 11, 12 are not assigned.
One idea is to use one of the digital out ports (1 or 2) that sends a continuous 24 V signal which can then go to a voltage regulator to get it down to 15 v for the comparator and then to another voltage regulator to get it down to 5 V for the sensor.
Or to use port 9 UP_24 V to a voltage regulator and then to the comparator, and port 10 UP_0 V to drive the sensor.
But is it possible to use port 9 and 10 and set them to a certain voltage?
If so I can make the circuit more simple in the 3D printed box.
Thank you.
