Power Rail Distribution and Voltage Surge Limits

The power feed module energizes up to 80 adjacent K-System isolator modules mounted on a continuous Power Rail UPR-03 track. Integrated decoupling diodes enable redundant dual power input supplies to operate simultaneously without back-feed risks. Internal protection circuitry enforces surge voltage protection limits, clamping high-voltage transient spikes before they reach downstream interface devices on the rail bus. An integrated monitoring circuit evaluates supply presence and diagnostic signals, triggering a volt-free relay contact upon detecting power loss or module fault conditions.

Field Installation Guidelines

Rail Assembly and Mechanical Alignment

Snap the module directly onto a standard 35 mm DIN mounting rail (EN 60079-15) fitted with a Power Rail insert.
Ensure the golden contact pins on the underside align firmly with the Power Rail bus conductors to maintain continuous contact pressure.

Wiring and Ground Integrity

Connect primary and secondary 24 VDC supply lines using separated cable routes to eliminate single-point physical fault risks.
Land signal and fault monitoring cables into the screw terminal blocks, ensuring tightening torque does not exceed 0.5 Nm.

Frequently Asked Questions

Q: What is the maximum current capacity supported through the Power Rail connections?

A: The KFD2-EB2.R2A.B delivers up to 4 A total current directly onto the Power Rail bus bar for downstream modules.

Q: How does the fault signal relay behave during a power failure event?

A: The volt-free fault relay contact de-energizes when either power feed input drops below the operational threshold or when a collective error is reported over the Power Rail bus.

Q: Can the module be swapped out while adjacent modules remain powered?

A: Hot-swapping the module is permitted if a second power feed module is operating redundantly on the same Power Rail segment without disrupting overall 24 VDC distribution.

Q: Does this feed module provide intrinsic safety (Ex i) barriers for field devices?

A: No, the KFD2-EB2.R2A.B functions solely as a non-hazardous side power distribution unit and diagnostic alarm collector for the K-System backplane.
