FAQ

Question?

Can the Z 728 Power Rail be cut to a custom length for a specific number of modules?

Answer:

Yes, the Power Rail is designed to be cut to the required length. However, after cutting, it is essential to re-attach the end cap (model K-END-CP) to ensure proper termination and safety.

Question?

What is the function of the second, smaller rail on the Z 728?

Answer:

The second rail is the collective error messaging bus. It allows all connected K-System modules with fault indication to signal an error to a single output module, like a KFD2-ER, simplifying system-wide diagnostics.

Question?

Is the Z 728 compatible with both K-System and H-System modules from Pepperl+Fuchs?

Answer:

No, the Z 728 Power Rail is specifically designed for the K-System termination boards. The H-System uses a different backplane and connection methodology and is not compatible with this Power Rail.
