- Product Introduction & Supply Chain Strategy
The Bently Nevada 133819-02 is an internal termination, 6-channel temperature monitor I/O module designed for the 3500/60 Machinery Protection System. It conditions sensor signals from RTDs and thermocouples to protect turbines, compressors, and high-value rotating equipment from over-temperature damage.
This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability. Refurbished cards carry severe risks of degraded components, which can cause false trips or unrecorded thermal spikes. Securing this module as New Surplus maintains full OEM reliability, lowers total cost of ownership (TCO), and shields your facility from extended lead times during emergency plant maintenance.

- Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
- Perform lock-out/tag-out (LOTO) on connected machinery if maintenance procedures require.
- Wear a grounded ESD wrist strap before handling the replacement module.
- Photograph existing terminal wiring connections, jumper options, and DIP switch configurations prior to pulling the old card.
Stage 2: Removal
- Loosen the upper and lower captive screws on the existing rear I/O module using a flathead screwdriver.
- Extract the module by pulling straight outward on the release levers to prevent bending or shearing the backplane connector pins.
Stage 3: Installation (Clone & Seat)
- Configure all DIP switches and hardware jumpers on the new 133819-02 module to mirror the original unit exactly.
- Slide the card into the rear rack guides until the backplane connectors fully seat. Hand-tighten the upper and lower captive screws.
- Reconnect terminal blocks according to your documented wiring diagram.
Stage 4: Power-On & Testing
- Verify 24 V DC power delivery to the 3500 system rack.
- Confirm that the channel status LEDs display solid green (RUN) and that the red (ERR/FAULT) light remains off.
- Connect via Bently Nevada 3500 Rack Configuration Software to verify temperature channel scaling and alarm setpoints.
- Firmware/Software Versions & Upgrade Notes
- Recommended Firmware: Operates with 3500/60 main processing card firmware revision 2.10 or higher.
- Compatibility Notice: Configuration requires Bently Nevada 3500 Rack Configuration Software (version 5.0 or later). Legacy software revisions may fail to recognize the hardware identification of newer board hardware revisions.
- Upgrade Caution: Avoid upgrading or flashing firmware during an emergency hardware replacement. Match the firmware on the replacement unit to the existing rack build to avoid communication timeouts or unexpected alarm states.
- Frequently Asked Questions (FAQ)
Q: Are these units really brand new, or are they refurbished/repaired cards?
A: This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules feature zero wear on backplane pins, zero soldered repairs, and original anti-static packaging opened only for mandatory QC testing.
Q: Why is New Surplus priced higher than refurbished parts on the market?
A: Refurbished modules often contain degraded capacitors and hidden electrical wear. Saving 500 on a used part can cost 50,000 in unplanned downtime when it fails. Our pricing reflects genuine, factory-fresh inventory that delivers a 10–15 year expected lifespan and zero failure risk out of the box.
Q: Is the 133819-02 hot-swappable while the 3500 rack is energized?
A: Yes, 3500 series I/O modules support live insertion and removal. However, pulling an active temperature module removes protection logic for those 6 channels. Always bypass the affected protection channels in the software before removing the card.
Q: Does the 133819-02 retain sensor calibration data onboard?
A: No. Alarm limits, sensor types (RTD vs. TC), and scaling values are stored in the main 3500/60 monitor card. The 133819-02 acts as the physical interface and signal conditioner.
Q: What warranty coverage applies to this module?
A: Every 133819-02 New Surplus card comes with a full 1-year replacement warranty, verified through physical pin inspection, backplane continuity testing, and ESD-safe packaging protocols.
