Bently Nevada 114M5335‑01 Low Voltage DC PIM for 3500/15
Overview
The 114M5335‑01 is a rear‑mount PIM interface module built for the Bently Nevada 3500 TSI machinery protection system. This Low Voltage DC PIM works cooperatively with the 3500/15 power supply unit and installs at the rear left slot of the 3500/05 rack. It accepts external 24VDC power source, completes filtering, surge suppression and fuse protection, then feeds conditioned power to the front‑panel 3500/15 low‑voltage DC power unit. The 3500/15 power unit converts power and supplies power for all internal cards within the 3500 rack.
Important Note: New‑generation 3500/15 AC/DC power supply and matching 114M5335‑01 Low Voltage DC PIM cannot be used with legacy power or PIM hardware. Mixed installation is strictly prohibited.

Typical Application Scenarios
The 114M5335‑01 Low Voltage DC PIM applies to rotating machinery protection for steam turbine, compressor, fan and gas turbine within Bently Nevada 3500 TSI systems. It is widely used in TSI monitoring cabinets for power generation, petrochemical and coal‑chemical industries, suitable for field cabinets equipped with only 24VDC power supply.

Troubleshooting Guide
- No rack power supply: Check external 24VDC input voltage to rear‑mount 114M5335‑01 PIM and inspect built‑in module fuse.
- PIM‑related alarm with 3500/15 status light error: Confirm version match between Low Voltage DC PIM and front‑panel power unit. Do not mix legacy and new‑generation hardware.
- Module replacement: Power off the full rack before removing rear‑side PIM. Front‑panel 3500/15 power unit supports live hot‑swap operation.

FAQ
What is 114M5335‑01?
It is a rear‑mount Low Voltage DC PIM power input module for Bently Nevada 3500 system. It pairs with the 3500/15 low‑voltage DC power supply unit installed on the 3500/05 rack rear side, receiving external 24VDC input and providing surge suppression plus fuse protection for rack power unit.
Where to install 114M5335‑01?
Installed on rear half‑height slot of 3500/05 rack, physical position corresponds to front‑panel 3500/15 power card.
What is input voltage rating?
Input range 20‑30VDC, nominal 24VDC DC power supply.
Can 114M5335‑01 directly replace 133300‑01?
No. 114M5335‑01 belongs to new‑generation Low Voltage DC PIM while 133300‑01 is legacy hardware. These two parts are hardware incompatible and must be paired with matching‑version 3500/15 power supply unit.
Does PIM module support hot swap?
Rear‑mount 114M5335‑01 PIM does not support hot swap; full rack power‑off is required for replacement. Front‑side 3500/15 power supply unit supports hot swap.
Is redundant power configuration available?
Yes. Dual 114M5335‑01 PIM plus dual 3500/15 power supply can be configured for automatic power fail‑over and improve TSI system power reliability.
How to troubleshoot no‑power issue on 3500 rack related to PIM?
1. Measure external 24VDC input voltage fed to PIM; 2. Inspect internal fuse status of PIM module; 3. Confirm part‑number and version match between Low Voltage DC PIM and 3500/15 power unit, do not mix different generations; 4. Check contact condition between rear‑side PIM and rack backplane.
Red alarm light on 3500/15 front panel, is power unit definitely damaged?
Not necessarily. Alarm can be triggered by abnormal PIM input, 24V power fluctuation or blown internal fuse. Inspect rear‑side PIM circuit first before replacing front‑panel 3500/15 power unit.
Which racks are compatible?
Compatible with 3500/05 19‑inch standard rack and 3500 series 14‑inch compact rack.
What is operating temperature range?
Operating temperature ‑30℃ ~ +65℃; storage ‑40℃ ~ +85℃; maximum humidity 95% non‑condensing.
Which card must be used together?
Must pair with front‑panel 3500/15 Low Voltage DC Power Supply. Two components work as one set and cannot be separated.
What are main application industries?
TSI protection for rotating equipment including steam turbine, compressor, fan and gas turbine. Applied for power plant, petrochemical and coal‑chemical industrial sites with 24VDC cabinet power source.
