KUKA KRC4 X12 connector pin configuration

    Hello,

    I am looking for the pin configuration for the KUKA KRC4 X12 connector with 16-16 IOB. It's a DB50F female connector on the controller. I want to connect an infrared sensor as an input and an external motor as an output to the controller.

    I know the mapping of the I/O in the WorkVisual, but I am not sure about the physical connection of I/Os and the power supply connection.

    Okay, the pin configuration for the KRC4 compact is fine. I understood the I/O connections but still don't know how to connect the power supply.

    I want to know if an external power supply can be directly connected to the X12 connector or if there are +24V and GND pins on the X12 connector.

    I do not want to use the X55 connector for the external power supply. Also, my controller has an I/O board instead of the Beckhoff I/O terminals.

    wait a second... this is a bit more convoluted than it looks.

    KUKA calls IO connectors X12 but there are different variants of it. the document shared by SkyFire is for Beckhoff IOs, not for IOB. And while mechanically both are using same connector style, pinout for those two is not the same...!

    So if you want to talk to talk and walk the walk do what KUKA robot users are advised to do:

    1. Read pinned topic READ FIRST

    2. Get correct documentation for your version of hardware/software. Latest documentation can be obtained from KUKA portal Xpert as mentioned in READ FIRST.

    3. When asking for support make sure to state clearly your product version (hardware/software).

    in most cases IOs on KRC4 are from Beckhoff. But couple of years ago KUKA also made IOB. IOB is only used in compact controllers. This frees up some of very limited space in the controller as IOB is not installed on a DIN rail but inserted into one of PCI slots. Also this is quicker to install and IOB can be used as both PNP and NPN type of IO. Check documentation closely for wiring info. PNP type is normally used as a standard around the world, except Japan (or some Japanese plants in other parts of the worls). Care must be taken when using NPN - NPN outputs are on separate pins. NPN inputs are at same terminals but their state is inverted.

    And if your controller has X55, you will have to use it. This is regardless if the used 24V is supplied internally or externally. My suggestion is to not use premade jumpers that KUKA provides. Crimp pins on a multiconductor cable. The other side of the cable can be then brought to terminals and there (rather than inside X55 plug) you can make desired jumpers based on your needs.


    Here is the more recent version of the document but... probably not latest. It does cover IOB though

    Okay, I understood. Sorry, I rushed through the 'Read First' section.

    Thank you for sharing the recent version of the optional interfaces manual. Now I am clear about the physical connections and the power supply.

    My doubt is clear now about the X12 connector. :smiling_face:
