Dear Sirs ,
i have kuka krc4 compact controller with EL 1889 16 digital inputs and EL 2889 16 digital outputs
which best method to connect these inputs / outputs
1- connect 24 VDC & 0 VDC from external power supply which supply all sensors & PLC and X12 ( X55 pin 5 & pin 6 )
in this method , KRC4 power supply is out
2- connect 0 VDC from PLC power supply to 0 VDC of KRC4 power supply
3- use solid state relays for KRC4 digital inputs and outputs ?
which method is common used and more safety ?
what about X41 power supply connection on robot arm KR agilus 6 axis ?
thank you
