U

S

Segment supply (I/O supply in the segment circuit)

The voltage U

S

supplies all of the devices connected to the segment circuit.

The voltage U

S

is supplied using a bus coupler or a power terminal or is tapped from the

main voltage U

M

at the bus coupler, a power terminal or a segment terminal and is led

through the potential jumper to the next power or segment terminal. (Exception: terminal

with a relay output interrupts the potential jumper)

U

ANA

I/O supply for analog terminals

The voltage U

ANA

is used to supply all the terminals for analog signals.

It is generated in the bus coupler or in a special power terminal and is led through the In-

line station by means of potential routing.

U

L

Communications power

The voltage U

L

is used to supply all the devices with communications power (supply of the

module electronics).

It is generated in the bus coupler or in a special power terminal and is led through the In-

line station by means of potential routing.

P

TOT

Power dissipation of the electronics

P

HOU

Power dissipation of the housing

C 2 Representations used in basic circuit diagrams

Local bus

(INTERBUS)

This designation represents the data jumpers for the local bus (two jumpers)

(sometimes still called INTERBUS).

U

L

This designation represents the following potential jumpers:

– Communications power (U

L+

)

– Communications power ground (U

L-

)

– Supply voltage for analog terminals (U

ANA

)

U

ANA

Supply voltage for analog terminals

U

S

+24 V DC segment voltage

U

M

+24 V DC main voltage

L Phase in the 120 V AC or 230 V AC voltage area

N Neutral conductor in the 120 V AC or 230 V AC voltage area
