4. Product Introduction
The Bently Nevada 350033-01-00 is the standard 16-Channel Relay Module for the 3500 Machinery Protection System. It delivers 16 programmable SPDT relay outputs driven by alarm logic from monitors in the rack.
It translates vibration, position, or process alarms into contact closures for external equipment control and annunciation. The -01-00 configuration provides the base relay functionality without additional options.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Relay does not activate | Incorrect logic assignment | ✅ High | Force relay via configuration software | Verify and correct alarm drive settings |
| Contact resistance high | Worn or contaminated contacts | ✅ High | Measure with multimeter | Replace relay module if out of spec |
| All relays unresponsive | Module power or seating | ✅ High | Check LEDs and rack supply | Reseat module firmly |
| False activation | Voting logic error | ✅ Medium | Review combined alarm conditions | Adjust logic voting in software |
| Intermittent contact | Terminal vibration | ❌ Medium | Check field wiring torque | Secure and inspect terminals |

6. Frequently Asked Questions (FAQ)
What does the -01-00 mean in 350033-01-00? -01 indicates the standard 16-channel relay output configuration and -00 denotes no additional memory or special options.
Can I configure relays for latching or failsafe operation? Yes. The alarm drive logic supports various behaviors including latching, timed, and failsafe modes. Set these in the 3500 configuration software.
How many contacts per relay? Each of the 16 relays is Form-C with normally open, normally closed, and common terminals.
Is this module required for basic 3500 operation? No. It is optional for applications needing hard-wired relay outputs. Many systems use it for trip and alarm interfacing.
Can I replace just the I/O portion? The main relay module and I/O work together. For full replacement, the complete assembly is recommended.
What testing is done before shipment? Each unit is powered in a test rack. We command every relay, verify contact operation, and confirm logic response to simulated alarms.
Why choose this over the 3500/32M? The 350033 gives you more channels (16 SPDT vs 4 DPDT). Use it when you need quantity of independent contacts rather than higher current DPDT pairs.
