BENTLY NEVADA 149986-01 3500/33 16-Channel Relay Control Module

Product Overview

The Bently Nevada 149986-01 is a spare 16-channel relay control module for the 3500 Machinery Protection System. It executes programmable alarm-drive and voting logic based on alarm states, equipment status, and measured variables from compatible monitor channels. It is designed to support machinery protection and control functions in industrial monitoring systems.

Important Notes

• The correct product type is a relay control module, not a signal conditioner.

• Model 149986-01 is the control module; a compatible rear relay output module is required for the complete relay assembly.

• Standard, failsafe, and low-current relay output modules have different specifications and should not be treated as interchangeable without compatibility checks.

• Confirm the installed rack configuration, rear I/O module, contact ratings, and software versions before ordering.

• Verify the exact part number, revision, and product condition before installation or replacement.
