The Bently Nevada 3500/32M-01-00, also cataloged as the 3500/32M 4-Channel Relay Module, operates as a dedicated hardware component for relay output switching and alarm logic execution within the Bently Nevada 3500 Machinery Protection System.

Model Configuration Overview

The 3500/32M-01-00 configuration identifies a 4-channel relay output module with no additional agency approval option. The module provides four SPDT relay channels for discrete control actions generated by the 3500 monitoring rack.

The relay outputs are used for alarm annunciation, protective shutdown circuits, and external control interfaces connected to machinery monitoring systems.

Hardware Specifications

Rotor Monitoring Relay Interface Characteristics

Within the 3500 platform, the 3500/32M relay module receives processed alarm states from monitoring modules and converts these conditions into physical relay contact outputs.

The module operates after signal evaluation performed by vibration and position monitoring cards. It does not perform eddy-current probe signal conditioning or gap voltage measurement directly, but functions as the final switching interface for protection logic.

The 3500 architecture supports machinery protection applications where relay outputs must follow validated alarm states from modules such as vibration monitors, position monitors, and process monitoring modules.

Installation Guidelines

• Install the module in an available slot position within a compatible Bently Nevada 3500 rack.
• Verify rack backplane compatibility before inserting the module.
• Ensure relay output wiring follows the required field circuit voltage and current ratings.
• Separate relay output wiring from low-level vibration sensor signal cables to reduce electrical interference.
• Connect protective grounding according to the 3500 rack installation requirements.
• Confirm external shutdown or alarm circuits before placing the relay outputs into service.

Frequently Asked Questions

• Can the 3500/32M-01-00 process vibration probe signals directly?

  No. The module provides relay output switching only. Vibration and position signal processing are completed by other 3500 monitoring modules.

• How many relay outputs are available on this module?

  The module contains four independent relay channels. Each channel uses a single-pole double-throw (SPDT) relay contact configuration.

• Is the 3500/32M-01-00 compatible with other 3500 Series racks?

  Yes. The module is designed for installation within the Bently Nevada 3500 Machinery Protection System rack platform.

• Does this module support hot swapping during system operation?

  Hot swapping capability depends on the complete 3500 rack configuration and installed procedures. Follow Bently Nevada maintenance instructions before removal.

• What type of electrical contacts are used inside the relay module?

  The module uses SPDT relay contacts with epoxy-sealed construction and installed arc suppression components.

• Does the module include agency approval options?

  This configuration, 3500/32M-01-00, is specified without an agency approval option.

• What environmental conditions affect module operation?

  The module is specified for operation from -30 deg C to +65 deg C with up to 95% non-condensing humidity.

• Can relay outputs connect directly to shutdown circuits?

  Yes, when the external circuit voltage and current remain within the relay contact specifications and system engineering requirements.
