Selection Guide
Use the following criteria to confirm the 125768-01 is the correct module for your application:
- ✅ Your system uses a Bently Nevada 3500 Series rack
- ✅ You require remote I/O expansion beyond the primary rack capacity
- ✅ Your installation requires distributed signal acquisition across multiple monitoring points
- ✅ You need API 670-compliant machinery protection
- ⚠️ If your rack is a 3300 or 1900 Series — a different module family is required; contact us for guidance
- ⚠️ If you need Ethernet-native communication — consider pairing with the 3500/92 gateway module
