7.1.2
The logic circuit with the communications power U
terminal (IB IL 24 PWR IN/R-PAC; IB IL 24 PWR IN/PS-PAC) and is led through all the
terminals of an Inline station.
The logic circuit (e.g., protocol chip, microcontroller) of the devices in a station is supplied
with voltage from the logic circuit.
The voltage in this circuit is 7.5 V DC ±5%.
The communications power U
terminal from the connected supply voltage.
The maximum current carrying capacity is 2 A. If this value is reached, the voltage must be
boosted via a power terminal or a new station must be created using a bus coupler.
The current consumption from the logic circuit of each device is specified in the
DB GB IB IL DEVICE LIST data sheet and the relevant terminal-specific data sheet.
The communications power is not electrically isolated from the 24 V DC input voltage for the
bus coupler.
7.1.3
The analog circuit with the supply for the analog terminals (also referred to as analog
voltage) U
IB IL 24 PWR IN/PS-PAC) and is led through all the terminals of an Inline station.
The I/O for analog signal terminals is supplied from the analog circuit.
The voltage in this circuit is 24 V DC (+20%, -15%).
The analog voltage U
from the connected supply voltage.
The maximum current carrying capacity is 0.5 A. If this value is reached, the voltage must
be boosted via a power terminal or a new station must be created using a bus coupler.
The current consumption from the analog circuit of each device that is supplied from U
is specified in the DB GB IB IL DEVICE LIST data sheet and the relevant terminal-specific
data sheet.
This maximum current carrying capacity can be limited by certain bus couplers or
corresponding power terminals. Please refer to the information in the terminal-specific
data sheets.
