Description

The Bently Nevada 3500/32 Relay Module is a full-height rack card designed for the 3500 Series Machinery Protection System. This module provides four independent relay outputs, enabling critical alarm and shutdown logic for industrial turbomachinery monitoring. It is engineered to interface with rack-based monitor channels to provide reliable, programmable actuation for safety-instrumented systems.

Features

  • Four independent SPDT (Single-Pole, Double-Throw) relay outputs.
  • Configurable Alarm Drive Logic supporting complex AND/OR combinations based on rack-wide monitor inputs.
  • Programmable via 3500 Rack Configuration Software.
  • Supports redundant relay configurations for high-integrity trip applications.
  • Epoxy-sealed arc suppression rated for 250 Vrms to extend contact life.
  • Integrated LED indicators for status monitoring (OK, TX/RX, and Channel Alarm).

Installation Guidelines

  • Ensure the 3500 rack is powered down before inserting or removing any module to prevent electrical damage.
  • The module consists of a main front card and a rear I/O module; ensure both are securely seated in the rack backplane.
  • Install in any slot to the right of the Rack Interface Module (RIM).
  • Use shielded cabling for relay output connections to minimize EMI/RFI interference in high-noise industrial environments.
  • Maintain proper ventilation within the cabinet to ensure the module operates within the specified -30 degC to +65 degC range.
  • Follow ESD (Electrostatic Discharge) safety precautions when handling the module to protect sensitive internal circuitry.

FAQ

What is the primary function of the 3500/32 module?

The 3500/32 is a relay output module that acts on alarm and danger conditions detected by other monitors within the 3500 rack, allowing for automated machinery shutdown or alarm notification.

Can I program the relay logic?

Yes, the relay channels are fully programmable using the 3500 Rack Configuration Software, allowing for custom Alarm Drive Logic including AND/OR voting schemes.

Is this module compatible with all 3500 series racks?

The 3500/32 is designed for standard 3500 series racks and must be installed in a slot to the right of the Rack Interface Module.
