Bently Nevada 3701/55 323073-01 Relay Output Module
The standard four-channel relay-output module for the 3701/55 ADAPT emergency-shutdown platform.
Key Information
3701/55 323073-01 identifies the standard four-channel relay-output module used with the Bently Nevada ADAPT ESD platform. It is a system component, not a complete configured emergency-shutdown monitor.
The -01 version must not be confused with 323073-02, which is the gold-plated relay execution. Relay material, terminal-base identity and configured voting logic all belong in the replacement review.
Functions
- Provides four relay-output channels for the configured 3701/55 shutdown and annunciation strategy.
- Interfaces with the matching ADAPT ESD terminal base and system processing hardware.
- Preserves the standard-relay hardware path when replacing the same documented module execution.

Installation
- Export and archive the active ESD configuration before hardware work begins.
- Confirm 323073-01 rather than the gold-plated -02 variant from the physical label.
- Isolate field circuits and verify terminal assignments against the approved shutdown drawing.
- Proof-test every affected relay path and final element before returning protection to service.
Lifecycle
- Keep relay proof-test records linked to the exact module serial identity.
- Maintain a controlled spare that matches the installed relay execution.
- Review the full safety function whenever processor, base or relay hardware changes.
FAQ
Can 3701/55 323073-01 replace 323073-02 directly?
Do not assume so. The -02 version uses gold-plated relays and does not carry the same hazardous-area certification context.
What must accompany a 3701/55 323073-01 quotation request?
Send the module label, terminal-base label, installed processor reference, wiring drawing and required relay execution.
Does replacing 3701/55 323073-01 require a proof test?
Yes. Every affected output, voting path and final element should be verified under the site safety procedure.
Is 3701/55 323073-01 a complete ESD monitor?
No. It is the relay-output module used within a configured ADAPT ESD system.
Why is the terminal base important for 3701/55 323073-01?
The base defines the physical system connection, so its identity and terminal mapping must match the installed design.
