Bently Nevada 3500/62 133811-03 – Process Variable Monitor | 3500 Series Machinery Protection Platform
Engineering Background: The Bently Nevada 3500 Series is the industry-standard machinery protection system deployed across power generation, oil & gas, petrochemical, and heavy industrial facilities worldwide. Engineered to API 670 standards, the platform delivers continuous, real-time monitoring of critical rotating machinery parameters to prevent catastrophic failures and unplanned downtime.
Product Positioning: The 3500/62 (P/N 133811-03) is a dedicated Process Variable Monitor module within the 3500 rack-based system. It accepts standard process transmitter inputs (4–20 mA, voltage) and converts them into fully conditioned, alarm-capable channels integrated with the 3500 system’s relay and communication architecture. This module is the preferred solution for procurement engineers requiring a single-platform approach to both vibration and process variable monitoring on critical assets.

- Flexible Input Conditioning: Accepts both current-loop (4–20 mA) and voltage transmitter outputs, eliminating the need for external signal converters.
- Integrated Alarming: Alert and Danger setpoints with configurable latching behavior, directly driving the 3500 relay module for automated shutdown logic.
- System 1 Integration: Full compatibility with Bently Nevada System 1 software for configuration, trending, and predictive diagnostics.
- Hot-Swap Capable: Module can be replaced under power in non-hazardous areas, minimizing maintenance downtime.
System Architecture & Signal Flow
The 3500/62 module occupies a single slot in the 3500 rack. Process transmitter signals (4–20 mA or voltage) are wired to the module’s I/O terminal block. The module conditions and scales the input, compares values against configured Alert and Danger setpoints, and transmits channel data across the TDI backplane to the 3500 Communication Gateway and Relay Modules. Alarm states are communicated to the plant DCS/SCADA via the gateway module (Modbus, Ethernet/IP, or FOUNDATION Fieldbus, depending on gateway variant). Configuration is performed offline or online via Rack Configuration Software (RCS) or System 1.

Technical FAQ
Q: Is 133811-03 compatible with all 3500 rack variants?
A: The 3500/62 module is compatible with standard 3500 racks. Verify your rack’s backplane revision and available slot type before ordering. Contact us if you need compatibility confirmation.
Q: Can this module accept HART-enabled transmitters?
A: The 3500/62 accepts standard 4–20 mA signals. HART communication is carried on the same loop but is not natively processed by this module; a separate HART multiplexer would be required for HART data extraction.
Q: What software is required for configuration?
A: Bently Nevada Rack Configuration Software (RCS) or System 1 software. Konmask can provide guidance on software version compatibility.
Q: Do you provide a warranty?
A: Yes. All units carry a 12-month warranty against manufacturing defects. Contact support@konmask.com for warranty claims.
Q: Can you supply the full 3500 rack system?
A: Yes. Konmask.com stocks a wide range of 3500 Series modules including power supplies, relay modules, communication gateways, and vibration monitors. Contact us for a complete BOM quotation.
