Supply Line and Power Supplies

General

In Fieldbus Boxes, a maximum of 4 A may flow through each pin - this applies to every module, and to all the connection versions: S8, M8 and M12.

Points you must watch

  • Current consumption of the Fieldbus Boxes (see Current consumption)
  • Current consumption of the sensors
  • Current consumption of the actuators
  • Cable length, and losses in the leads (see Conductor losses)
  • If the power line is taken on to other devices, ensure that the maximum current is not exceeded (see previous points)

Note:

Example 1:

If, for example, all 8 outputs of an IP2001-Bxxx are loaded simultaneously with 0.5 A, then in this case the power continuation facility must not be used, as this could result in destruction of the connection or of the device.

Example 2:

Channels 0..3 of an IP/IE204x are connected, which means that only 2 of the 4 channels may be loaded with 2 A.
