Description

The Bently Nevada 136188-02 is an Ethernet/RS485 Modbus I/O module designed for integration with the 3500/92 Communication Gateway within the Bently Nevada 3500 Series Machinery Health Monitoring System. This module acts as the critical interface between the 3500 rack and external automation systems, facilitating real-time data exchange for condition monitoring, predictive maintenance, and system optimization. It provides both Ethernet TCP/IP connectivity and serial RS485 communication, ensuring compatibility with modern control systems and legacy serial Modbus networks.

Features

  • Ethernet TCP/IP communication via RJ45 connector for 10BASE-T networks.
  • Serial RS485 communication interface for Modbus RTU protocols.
  • Configurable Modbus Register Utility for flexible data mapping.
  • Front-panel LED indicators for OK and TX/RX status monitoring.
  • Field-upgradable firmware support via 126M4118-01 kit.

Applications

  • Nuclear, thermal, and hydropower plant machinery monitoring.
  • Turbine bearing and stator winding temperature and vibration monitoring.
  • Pump and motor condition assessment.
  • Gearbox lubrication and internal friction detection.
  • Continuous protection for industrial fans, blowers, and extruders.

Technical Specifications

Model 136188-02
Communication Ethernet (TCP/IP) / Serial (RS485)
Input Impedance > 1 MΩ
Operating Temperature -30 degC to +65 degC
Storage Temperature -40 degC to +85 degC
Power Consumption 5.6 W (typical)
Operating Voltage 24 V DC +/- 10%

Installation Guidelines

  • Ensure the 3500 rack is powered down before inserting or removing the module.
  • Use a standard 10BASE-T (or better) shielded Category 5 cable for Ethernet connections.
  • For RS485 serial communications, ensure proper grounding of the communication lines to minimize noise interference in industrial environments.
  • The 136188-02 is a rear-inserting I/O module; it requires the 136180-01 front-inserting Communication Gateway module to operate as a complete 3500/92 system.
  • Handle with standard ESD precautions to protect sensitive internal circuitry.

FAQ

What is the 136188-02?

The Bently Nevada 136188-02 is an Ethernet/RS485 Modbus I/O module designed for the 3500/92 Communication Gateway.

What is the core function of the 136188-02 module?

It transmits real-time monitoring statuses, direct vibration levels, and gap values from the 3500 rack to external platforms.

What is the difference between the 136188-01 and 136188-02 variants?

The 136188-01 variant utilizes RS232 serial communication, whereas the 136188-02 model uses RS485 physical layer communication alongside the standard Ethernet connection.

Is this module a full standalone gateway?

No, the 136188-02 is a rear-inserting physical I/O module. It must be paired with the front-inserting 136180-01 main Communication Gateway module to function.
