Description
1. Product Overview
The Bently Nevada 149992-01 is a high-density 16-Channel Relay Module designed for the 3500 Machinery Protection System. As the primary control unit for the 3500/33 system, it provides 16 independent, fully programmable relay outputs to facilitate complex alarm and shutdown logic.
This module is specifically engineered for industrial environments where a high concentration of discrete outputs is required in a minimal footprint. By utilizing the 3500 Rack Configuration Software, users can assign any combination of monitor channel statuses to any of the 16 relays, supporting sophisticated “voting” logic (e.g., 2-out-of-3) to ensure maximum asset protection and operational uptime.
Key Applications:
- High-Density Alarm Management: Ideal for systems requiring extensive discrete signaling to annunciator panels or DCS.
- Automatic Machinery Shutdown: Critical for triggering Emergency Shutdown (ESD) sequences based on vibration or temperature alarms.
- Complex Logic Implementation: Handles “AND/OR” logic across multiple monitor modules within a single 3500 rack.

7. FAQ
Q: What is the advantage of using the 149992-01 over the 4-channel 3500/32?
The 149992-01 (3500/33) provides four times the output capacity in the same rack space. It is significantly more cost-effective for applications requiring many discrete outputs, and it allows for more complex logic combinations that are not possible with the 4-channel module.
Q: Is the 149992-01 compatible with older 3500 racks?
Yes, it is designed for the standard 3500 rack backplane. However, you must ensure that your Rack Configuration Software is updated to a version that supports the 3500/33 16-channel module.
Q: Does this module include the rear terminal block?
No, 149992-01 is the main monitor module (front). To connect your field wiring, you must also have the corresponding rear I/O module (e.g., 136180-01 for internal wiring). Please let us know if you need both.
