Bently 149992-01 I/O Terminal Board
Product Dimensions:
1. Product Detailed Description
The 149992-01 is a full-height I/O module that provides 16 independent relay outputs. It works in conjunction with the 3500/33 Relay Main Module. Its primary role is to act as the interface for “voting logic,” where it receives alarm or status signals from other monitor modules in the 3500 rack (like vibration or temperature monitors) and triggers an output to shut down machinery, sound an alarm, or signal a PLC/DCS.
-
Logic Configuration: Each relay can be independently programmed using AND and OR logic.
-
Termination: Typically used with internal termination headers for direct wiring.

3. Product Advantages
-
High Density: Provides 16 channels in a single rack slot, maximizing the efficiency of the 3500 rack space.
-
Highly Programmable: Supports complex “Alarm Drive Logic,” allowing users to combine multiple inputs (e.g., Alert + Danger from different sensors) to trigger a single relay.
-
Safety & Reliability: Epoxy-sealed relays with standard arc suppressors ensure a long service life and high reliability in harsh industrial environments.
-
Status Monitoring: Features onboard LEDs (OK, TX/RX, and Channel Alarm) for immediate visual diagnostics of the module and individual relay states.
4. Cautions & Precautions
-
TMR Limitation: This module is not intended for Triple Modular Redundant (TMR) applications; TMR systems must use the 3500/34 relay module instead.
-
Relay Energization: Relays can be set to “Normally Energized” or “Normally De-energized.” Ensure this setting matches your fail-safe requirements to prevent accidental machine trips during power loss.
-
Arc Suppression: While arc suppressors are installed, ensure that external inductive loads are properly snubbed to avoid premature contact wear.
-
Installation: Always use a grounding wrist strap when handling the module to prevent Electrostatic Discharge (ESD) damage.
5. Product Applications
The 149992-01 is used to automate safety actions for critical rotating assets:
-
Emergency Shutdown (ESD): Automatically tripping a turbine or compressor when vibration levels exceed “Danger” setpoints.
-
Annunciator Panels: Driving remote light boxes or sirens in a control room to alert operators of machinery issues.
-
DCS/PLC Interface: Providing dry contact inputs to plant-wide control systems for status tracking.
-
Auxiliary Control: Managing auxiliary equipment like cooling fans or oil pumps based on temperature or pressure thresholds.
