8.1.4 Main circuit

The main circuit with the main voltage U

M

starts at the bus coupler or a power terminal

and is led through subsequent terminals until it reaches the next power terminal.

Please note the special requirements of Inline terminals with relay outputs. These

terminals interrupt the potential jumpers U

M

and U

S

.

A new circuit starts at the next power terminal. This circuit is electrically isolated from the

previous one if electrically isolated power supply units are used.

Several power terminals can be used within one station.

Function The segment voltage U

S

can be tapped from the main voltage U

M

using different segment

terminals. Several independent segments can thus be created within the main circuit. The

main circuit provides the supply voltage for these segments.

Some terminals access the main circuit directly. For example, the encoder supply for po-

sitioning terminals is tapped from the main circuit, while the I/O is supplied from the seg-

ment circuit.

Voltage The voltage in this circuit must not exceed 30 V DC.

Current carrying capacity The maximum current carrying capacity for the main circuit is 8 A (total current with the

segment circuit).

This maximum current carrying capacity can be limited by certain terminals. Please

refer to the information in the terminal-specific data sheets.

If the limit value of the potential jumpers U

M

and U

S

is reached (total current of U

S

and

U

M

), a new power terminal must be used.

Provision of U

M

In the simplest case, the main voltage U

M

can be supplied at the bus coupler.

The main voltage U

M

can also be supplied via a power terminal. A power terminal must

be used if:

1 A bus coupler that cannot supply the main voltage is used.

2 Different voltage areas (e.g., 24 V DC and 120 V AC) are to be created.

3 Electrical isolation between different I/O areas is to be created.

4 The maximum current carrying capacity of the potential jumpers U

M

, U

S

, and GND

(total current of U

S

and U

M

) is reached.
