Description

The Bently Nevada 3500/34 is a 4-channel relay module designed for use within the 3500 Machinery Protection System. This module provides four relay outputs, each utilizing single-pole, double-throw (SPDT) contacts to facilitate alarm and trip logic execution. The module is engineered for high reliability in industrial monitoring environments, featuring epoxy-sealed relays and integrated arc suppression to protect contact integrity during switching operations.

Features

• Four independent relay channels per module.
• SPDT (Single-Pole, Double-Throw) relay configuration.
• Integrated arc suppression rated at 250 Vrms.
• Epoxy-sealed relay construction for environmental protection.
• Typical power consumption of 5.8 Watts.
• Designed for seamless integration into the 3500 rack backplane.

Technical Specifications

Installation Guidelines

• Ensure the 3500 rack power is disconnected before installing or removing the module.
• Slide the module into the designated rack slot, ensuring the backplane connectors are properly aligned.
• Secure the module using the front panel captive screws to ensure proper grounding and mechanical stability.
• Verify that all field wiring is routed away from high-EMI sources to prevent signal interference.
• Maintain proper ventilation within the cabinet to ensure the operating temperature remains within the specified -30 degC to +65 degC range.

FAQ

What is the primary function of the 3500/34 module?

The 3500/34 is a relay output module that allows the 3500 system to trigger external alarms, shutdown systems, or other logic-based responses based on the status of monitored machinery parameters.

Are the relays in this module replaceable?

The 3500/34 relays are epoxy-sealed for environmental robustness; the module is designed as a field-replaceable unit rather than a component-level repairable device.
