The power repeaters fulfil the following tasks:

• Potential separation between bus segments

• Preparing the data signal bidirectionally.

• Power supply to the bus nodes through the bus line.

• Diagnostics via LEDs.

No configuration is required for power repeaters. From the point of view of the seg-
ment coupler/bridge, they are invisible.

Fuchs GmbH offers different power repeater that can be optimized for cor-
responding ranges of application.

1. KLD2-PR-Ex1.IEC, power repeater with 70 mA power supply current for connecting

to field bus systems in accordance with the FISCO model or for connection to a field
bus system in accordance with the Entity model (for description 

See section 4

).

2. KLD2-PR2-Ex1.IEC, power repeater for installation in Zone 2 with 70 mA power

supply current for connection to field bus systems in accordance with the FISCO
model or for connection to the field bus system in accordance with the Entity model
(for description 

See section 4

).

3. KLD2-PR-Ex1.IEC1, power repeater with 100 mA power supply current for con-

necting to field bus systems in accordance with the FISCO model (for description

See section 4

).

4. KLD2-PR2-Ex1.IEC1, power repeater for installation in Zone 2 with 100 mA power

supply current for connection to field bus systems in accordance with the FISCO
model (for description 

See section 4

).

5. KLD2-PR-1.IEC, Power repeater with 400 mA power supply for non-intrinsically

safe field bus systems.

6. KLD2-PR-NI1.IEC, power repeater with 215 mA power supply current for applica-

tions in ignition protection class "Non Incendive“.
