Configured for 20 to 30 VDC field power entry in the 3500 Machinery Protection System, the Bently Nevada 3500/15-04-04-01 ([133300-01] Low Voltage DC Power Input Module) provides direct physical/electrical execution at the rear rack backplane.

Model Suffix Decoding

3500/15 : Base power supply assembly, half-height left-side rack slot.
-04 : Upper slot input type 04 = Low Voltage DC (20 to 30 VDC).
-04 : Lower slot input type 04 = Low Voltage DC (20 to 30 VDC), redundant dual-supply build.
-01 : Approval option 01 = CSA/NRTL/C.
133300-01 : Order number of the Low Voltage DC Power Input Module (PIM) mated to 3500/15-04-x-xx.

Eddy-Current Probe Scaling and Gap Voltage Stability

The 133300-01 feeds a regulated 24 VDC rail that drives proximity probe driver circuits on 3500/42M and 3500/40M monitors. Eddy-current probe scaling against a known target shim depends on a low-ripple 24 VDC excitation; conducted noise from an unfiltered 24 VDC battery bus degrades the -10 VDC gap voltage validation window and shifts commutation thresholds in rotor dynamics math. The PIM's terminal-block entry plus EMI filtering enforces a galvanic boundary between field DC and backplane, suppressing cross-talk from adjacent high-current conductor runs into the monitor channel front ends.

Rear Slot Wiring and Grounding

Slot Lock: Insert only behind a 3500/15-04 Low Voltage DC supply. Mixing with 129478-01 (HVDC PIM) or 125840-02 (LVAC PIM) violates backplane keying and will not seat.
Torque: Tighten terminal screws to the value stated in the 3500 System Installation Manual. Under-torque raises contact resistance; over-torque strips the block.
Conductor: Size for full rack draw from the 24 VDC source. Do not parallel the 133300-01 output with any external 24 VDC supply.
Shield Drain: Terminate cable shields on the rack ground stud, not on the PIM terminal. Keep power conductors separated from transducer extension cables by the rack cable duct wall.

Frequently Asked Questions

Is the 133300-01 hot-swappable while the 3500 rack is live?

Only if the second 3500/15 supply is installed and healthy. With dual LVDC supplies, removing one PIM does not drop the backplane. Single-supply racks must be de-energized before PIM extraction.

What fuse is fitted inside the 133300-01?

The replacement fuse listed for the Low Voltage DC PIM is 01720045 (5 A slow-blow class). Do not substitute AC PIM fuse 01720025; voltage and time-delay characteristics differ.

Can 133300-01 accept 48 VDC from a telecom battery bank?

No. Rated input is 20 to 30 VDC. 48 VDC sits outside the 3500/15-04 regulation headroom and will open the internal fuse or damage the input filter stage.

Does the PIM perform voltage regulation itself?

No. The 133300-01 is a passive filtered input interface. Regulation to 24 VDC backplane power is executed by the mated 3500/15-04 supply module, not by the PIM.

What indicates PIM-side fault versus supply-module fault?

The 3500/15 front-panel "Supply OK" LED reports the supply module status. If OK is lit but rack powers down, suspect reverse-polarity or open PIM terminal. If OK is dark, the supply module or its PIM input is failed.

Can upper and lower slots mix LVDC and HVDC via two PIMs?

Yes, the 3500/15 chassis permits mixed types (e.g., -04 upper, -03 lower). But each slot requires its matching PIM: 133300-01 for -04, 129478-01 for -03. Do not cross-install.

Is there firmware or configuration EEPROM on the 133300-01?

No microprocessor, EEPROM, or firmware exists on the PIM. No flash tool, no revision file, no compatibility matrix beyond mechanical and voltage class.

What torque and wire prep apply to the terminal block?

Strip to the length printed on the terminal carrier, use bootlace ferrules on stranded conductors, and torque to the manual's stated Nm. Exceeding torque cracks the phenolic block; falling short causes thermal rise under 5 A load.
