BENTLY NEVADA 149992-01 3500/33 16-Channel Relay Output Module

Product Overview

The Bently Nevada 149992-01 is a spare 16-channel relay output module for the Bently Nevada 3500 Machinery Protection System. It provides relay contacts for alarm signaling, equipment interlocks, and machinery protection control actions. Each relay channel can be configured using the compatible 3500 system software to respond to alarm states, equipment status, and measured variables.

Important Notes

• This model is a relay output I/O module, not a signal conditioner.

• The 149992-01 output module is distinct from the 149986-01 relay control module; verify that the required components are present for the intended assembly.

• Switching ratings depend on the load type and installation conditions. Hazardous-area and functional-safety applications may require reduced voltage limits.

• Confirm rack compatibility, relay contact requirements, and the existing system configuration before ordering.

• Verify the complete part number, revision, and product condition before installation.
