Description

The Bently Nevada 3500/33-01-05, also cataloged as the 3500/33 16-Channel Relay Module, operates as a dedicated hardware component for programmable relay output control within the 3500 Machinery Protection System.

Hardware Specifications

Rotor Dynamics and Relay Signal Interface

The Bently Nevada 3500/33-01-05 provides programmable relay output execution for machinery condition monitoring applications within the 3500 platform. The module receives configured alarm states from the monitoring rack and transfers discrete relay signals for alarm, trip, and external control functions.

The module supports independent relay configuration and voting logic functions for machinery protection operations. Relay states follow the configured monitoring logic, allowing external circuits to respond to defined machine condition events.

The 3500/33 relay architecture maintains separation between monitoring decisions and field relay outputs. The module provides controlled interface behavior for shutdown circuits, annunciation systems, and external control equipment connected to the machinery protection network.

Frequently Asked Questions

Q: What relay functions does the 3500/33-01-05 support?
A: The module supports programmable relay outputs for alarm, trip, and control applications within a compatible 3500 Machinery Protection System.

Q: Does the module support relay voting logic configuration?
A: Yes. The module supports configured relay voting logic for machinery protection operations.

Q: What rack installation method is required for the 3500/33-01-05?
A: The module requires a 3500 Rack full-height front slot installation with the corresponding rear I/O module connection.

Field Installation Guidelines

Install the 3500/33-01-05 in the assigned full-height front slot of the 3500 rack. Confirm correct alignment between the front module and rear I/O module before securing the assembly.

Connect relay field wiring according to the approved site electrical drawings. Keep relay signal cables separated from high-voltage power wiring to reduce electromagnetic interference.

Apply proper cable shielding and grounding practices according to the installation environment. Verify terminal connections, rack power status, and system configuration before enabling connected alarm or trip circuits.

Before module replacement or removal, place connected machinery protection functions into the required maintenance state and confirm that relay outputs remain controlled during service activities.
