Bently Nevada 136180-01+136188-01 3500/92 Communication Gateway Module + Ethernet/RS232 Modbus I/O Module

Description

The 136180-01+136188-01 combination consists of the 3500/92 Communication Gateway Module main card (136180-01) and the associated Ethernet/RS232 Modbus I/O Module rear card (136188-01). This module set establishes digital communication links between the Bently Nevada 3500 Machinery Protection System and external plant automation platforms.

The gateway collects static measurement data, system event lists, and alarm statuses directly from the 3500 rack backplane and translates the information into standard Modbus protocols. Utilizing the 136188-01 rear I/O card, it offers hardware interfaces for Modbus communication over Ethernet networks and point-to-point RS232 serial connections. Plant operators use the 136180-01+136188-01 to integrate vibration monitoring values, thrust positioning, and system diagnostic events directly into Distributed Control Systems (DCS), Programmable Logic Controllers (PLC), and Human-Machine Interfaces (HMI).

Features

• Integrates the 3500/92 main monitor board with an Ethernet/RS232 rear I/O card.
• Supports Modbus TCP/IP communication over Ethernet and Modbus RTU/ASCII over serial connections.
• Transmits static values, alarm events, and system statuses across redundant digital channels.
• Configurable Modbus register mapping via 3500 System Rack Configuration Software.
• Maintains galvanic isolation between field interfaces and the internal rack logic.

Applications

• Integration of 3500 machinery protection data into DCS and PLC networks
• Remote monitoring of turbomachinery static vibration and position parameters
• Industrial automation control loops requiring real-time machinery state data
• Plant-wide condition monitoring and data historian integration

Installation Guidelines

• Install the 136180-01 main card into a full-height slot on the front of the 3500 rack.
• Mount the 136188-01 I/O module in the rear of the rack directly behind the 136180-01 main card.
• Ensure cable shields are grounded according to system installation practices to minimize EMI/RFI noise.
• Configure Modbus slave address, baud rate, and network IP settings through the 3500 System Configuration Software prior to commissioning.
