Allen Bradley 1606‑XLSRED Redundancy Module Power Supply

Configured for DC redundancy management in 1606‑XLS power distribution networks, the Allen Bradley 1606‑XLSRED (1606‑XLSRED redundancy module) provides direct electrical ORing and load‑sharing behavior for parallel DC supply configurations.

Hardware Specifications

Backplane Bus Communication Velocity and I/O Density Scaling

Within Allen Bradley supply architectures, the 1606‑XLSRED aligns with deterministic DC distribution rules that govern ORing and load‑sharing behavior. The module maintains stable conduction paths under varying supply voltages, preventing reverse current flow between paralleled supplies. Firmware flash compatibility is not applicable, but system‑level I/O density scaling is supported through modular DIN‑rail expansion, allowing multiple supply branches to be paralleled without altering upstream bus characteristics.

Frequently Asked Questions

Q: Can the 1606‑XLSRED be hot‑swapped? A: No. The DC supply branch must be de‑energized before inserting or removing the module to avoid transient ORing states.

Q: Does the module regulate voltage? A: No. It performs ORing and redundancy functions only; voltage regulation is handled by upstream 1606‑XLS power supplies.

Q: Are there limits on passthrough current? A: Yes. The module is rated for 20 A output and 480 W; exceeding these values may trigger protective behavior.

Field Installation Guidelines

• Ensure all DC supply branches are de‑energized before installation.
• Mount the module on a DIN‑35 rail to maintain correct thermal spacing.
• Route DC wiring separately from high‑frequency conductors to reduce noise coupling.
• Verify conductor size and torque according to supply branch requirements.
• Confirm LED indication after energizing to validate ORing path integrity.
• Maintain IP20 environmental conditions and avoid conductive dust exposure.
