Bently Nevada 3500/33 149986-01

Bently Nevada 3500/33 149986-01

Product Overview: The 149986-01 is the main control module PWA (Printed Wiring Assembly) for the Bently Nevada 3500/33 16-Channel Relay Module. This is the core processing card that manages the alarm drive logic for all 16 relay outputs. It works in conjunction with the companion relay output module (149992-01) to provide the complete 16-channel relay function. The 3500/33 is a full-height module that provides 16 independently programmable relay outputs, offering significantly higher relay density compared to the 4-channel 3500/32 module.

Description

Bently Nevada 3500/33 149986-01

Technical Specifications:

  • Module Type: Full-height, 16-channel relay control module (main PWA)
  • Power Consumption: Approximately 5.0 watts typical
  • Operating Temperature: -30°C to +65°C (-22°F to +150°F)
  • Storage Temperature: -40°C to +85°C (-40°F to +185°F)
  • Humidity: 95% non-condensing
  • Agency Approval Options: CSA/NRTL/C available (part number suffix “-01”) or no approval (“-00”)

Functional Features:

  • Controls 16 independently programmable relay outputs via the companion output module
  • Each relay contains “Alarm Drive Logic” programmable using AND and OR logic
  • Alarm inputs include Alert and Danger states, Not-OK status, or individual PPL from any monitor channel
  • Supports complex voting logic for critical machinery protection
  • Front panel LEDs indicate module OK status and TX/RX communication
  • Requires 3500 Rack Configuration Software version 3.3 or higher
  • Requires 3500/22 Transient Data Interface module with firmware version 3.3 or higher
  • Requires 3500 Data Acquisition Software version 2.40 or higher
  • Requires 3500 Data Display Software version 1.40 or higher
  • Not compatible with the 3500/93 LCD display module
  • When used with the 3500/94 VGA display module, hardware version 2.0 or higher is required

Application Scenarios:

  • High-density relay output applications requiring more than 4 channels
  • Complex voting logic implementations for critical machinery
  • Multi-machine monitoring systems with extensive alarm routing
  • Power generation, petrochemical, and metallurgical plant protection systems

Performance Parameters:

  • Channel count: 16 independent relay channels (via companion output module)
  • Relay response time: Less than 10 ms typical
  • Logic combinations: Unlimited AND/OR combinations of rack alarm inputs

Material Composition:

  • High-reliability electronic components on multi-layer PCB
  • Metal module enclosure with conformal coating
  • Gold-plated backplane edge connectors

Structural Features:

  • Full-height module form factor
  • Front panel with OK and TX/RX LED indicators
  • Plug-in design compatible with any accessible rack slot to the right of the TDI module
  • Requires companion I/O module (149992-01) installed in the rear slot

Working Principle:
The 149986-01 main control module receives alarm status information from all monitor modules in the rack via the backplane bus. It evaluates the programmed AND/OR alarm drive logic for each of the 16 relay channels and sends the appropriate drive signals to the companion relay output module (149992-01), which physically switches the relay contacts.

Installation Requirements:

  • Install the main control module (149986-01) in any full-height slot to the right of the TDI module
  • Install the companion relay output module (149992-01) in the corresponding rear slot
  • Configure relay logic using 3500 Rack Configuration Software version 3.3 or higher

Usage Notes:

  • The 149986-01 is the control module only — it requires the companion 149992-01 output module for complete functionality
  • The 3500/33 is not compatible with the 3500/93 LCD display module
  • For applications requiring fewer relay channels, the 3500/32 4-channel relay module is an alternative
