Bently Nevada 149986-01 16-Channel Relay Control Module

The Bently Nevada 149986-01 is a 16-Channel Relay Control Module, supplied as a spare part for use within the Bently Nevada 3500 Series Machinery Protection System. This module is engineered to provide a reliable interface between the monitoring system and external control elements such as alarms, shutdown circuits, or process control systems. It enables operators to respond promptly to critical machinery conditions by activating external relays in real time.

This spare module is functionally identical to the primary relay control modules in active use, making it suitable for immediate replacement, system expansion, or preventive maintenance planning.

Main Features:

The 149986-01 module includes sixteen independent relay output channels. Each channel can be individually configured to respond to user-defined conditions such as system alarms, machine vibration levels, or other logical combinations of events. These relays provide dry-contact outputs that are used to trigger alarms, initiate shutdowns, or control auxiliary equipment.

The module supports a wide range of configurations and operational modes, giving system integrators and plant operators full control over how and when outputs are activated. The flexible configuration capabilities allow relays to be tied to alert levels, danger levels, or customized combinations of monitoring parameters.

Designed for High-Reliability Environments:
Built to meet the demanding requirements of industrial and critical infrastructure environments, the 149986-01 is constructed using high-quality, durable components. It is capable of long-term performance in high-vibration, high-temperature, and electrically noisy environments, such as those found in power generation, petrochemical processing, and large-scale manufacturing facilities.

Hot-Swappable for Reduced Downtime:
As part of the 3500 system architecture, this relay module is designed to be hot-swappable. When configured in a redundant system, it can be removed and replaced without shutting down the rack or disrupting system functionality. This capability helps maintain high system availability and supports efficient field servicing.

Spare Part Utility:
The 149986-01 is supplied specifically as a spare part, ensuring operators and maintenance teams have immediate access to replacement components in the event of failure or during scheduled maintenance. Keeping spare modules on hand is considered best practice for facilities relying on continuous monitoring and protection of critical assets.

Applications:
This module is widely used in systems monitoring rotating machinery such as turbines, compressors, pumps, and motors. It is ideally suited for facilities that demand high levels of reliability and rapid response to machine conditions, including:

• Power generation stations

• Oil and gas processing plants

• Chemical and petrochemical facilities

• Pulp and paper mills

• Water treatment plants

• Any facility utilizing Bently Nevada 3500 Series systems
