2.6.3 Field Supply

2.6.3.1 Connection

Sensors and actuators can be directly connected to the relevant channel of the

bus module in 1-/4 conductor connection technology. The bus module supplies

power to the sensors and actuators. The input and output drivers of some bus

modules require the field side supply voltage.

Power supply modules provides field side power. Power supply modules are

available for other potentials, e.g. DC 24 V or AC 230 V. Likewise, with the

aid of the power supply modules, various potentials can be set up. The

connections are linked in pairs with a power contact.

The supply voltage for the field side is automatically passed to the next

module via the power jumper contacts when assembling the bus modules .

The current load of the power contacts must not exceed 10 A on a continual

basis. The current load capacity between two connection terminals is identical

to the load capacity of the connection wires.

By inserting an additional power supply module, the field supply via the

power contacts is disrupted. From there a new power supply occurs which

may also contain a new voltage potential.
