If The Bus Provides Power To Field Devices What Current Level Is Avai

1.	If The Bus Provides Power To Field Devices What Current Level Is Available?
Answer» PROFIBUS PA does supply power for intrinsic SAFE DEVICES connected with TWISTED PAIR. This is DONE according to IEC 1158-2 specification (maximum current is 120 mA per coupler for intrinsic safe operation and >300mA for non intrinsic safe operation). PROFIBUS PA does supply power for intrinsic safe devices connected with twisted pair. This is done according to IEC 1158-2 specification (maximum current is 120 mA per coupler for intrinsic safe operation and >300mA for non intrinsic safe operation).
