2. Product Introduction
The 129486‑01 + 129478‑01 pair blends stable rack power delivery with high-fidelity transient event logging inside the modular 3500 Series protection system. The 129486‑01 module provides reliable 24 V DC rack power. The 129478‑01 module captures detailed transient data—such as vibration hits or electrical spikes—enabling early fault detection and deeper diagnostic insights. This combination offers both power reliability and advanced data intelligence within a compact, maintainable rack footprint.
3. Product Applications
Ideal use cases include:
-
Machinery protection systems needing high‑speed transient data capture (e.g., during machine starts or abnormal events)
-
Systems requiring both power redundancy and event diagnostics in one slot
-
Critical industries like power generation, oil & gas, petrochemical, or heavy manufacturing
-
Facilities needing predictive maintenance through early detection via event capture
-
Environments where module maintenance must not interrupt ongoing protection operations
4. Product Advantages

Q1: What function does the 129486‑01 module serve?
A1: Supplies stable 24 V DC power to the rack system—essential for module operation.
Q2: What does the 129478‑01 module add?
A2: Captures high-resolution transient data during machinery events for deep analysis.
Q3: Can these modules be serviced while the system remains active?
A3: Yes—but only if redundancy is enabled, allowing safe hot-swapping.
Q4: What are the visual cues for module status?
A4: Power OK and Fault indicator LEDs on each module provide diagnostic clarity.
Q5: What is the combined power capacity?
A5: Typically between 150–200 W, sufficient for rack power and event capture electronics.
Q6: Are they compatible with older rack systems?
A6: Yes—they conform to the standard half-height form factor used across generation of racks.
Q7: What protections are built in?
A7: Overload and short-circuit protection are included to protect both the module and rack.
Q8: How does the transient data enhance monitoring?
A8: It provides granular event data (spikes, rev changes) that enables predictive diagnostics earlier.
Q9: Which environments are these modules suited for?
A9: Ideal for industrial settings with heavy duty, wide temperature ranges, and noisy electrical conditions.
Q10: What if module failure occurs?
A10: With redundancy, system continues running. The failed unit can be replaced without interruption.
