Profibus is the most widely used field bus. It is promoted by Siemens and by organized, interested and committed manufacturers and users in the PNO (Profibus user organization). The IP 20 interface on the device side is standardized as a 9-pin D-Sub female connector. The max. data transmission rate is 12 Mbit/s.
The cable is a shielded twisted pair conductor. The cable sheath is violet and the signal cores are green (A) and red (B).
With its comprehensive program, ERNI provides customers with a wide variety of options.
Particular emphasis should be placed on the different termination technologies, from the traditional screw terminal to the cage clamp terminal to the IDC terminal.*
* Due to continuous advancement, it is possible that the UL approval of a new version may not have been completed at the time of going to press.
