The Bently Nevada 136188-01 is a specialized rear I/O module designed to work in conjunction with the 3500/92 Communication Gateway main module. It provides the physical connectivity required to export vibration, position, and temperature data from a 3500 rack to external systems. By offering both Ethernet and RS232 ports, it allows for simultaneous high-speed data acquisition via Modbus/TCP and local configuration or serial integration via Modbus RTU.
Specifications

Features
Dual Interface Design: Combines a 10Mbps Ethernet port and a serial RS232 port on a single I/O card for flexible system integration.
Modbus Gateway Functionality: Translates internal rack data into industry-standard Modbus registers for seamless communication with DCS, PLC, and SCADA systems.
Configurable Register Utility: Supports the 3500/92 utility which allows users to map specific rack values into custom Modbus registers for efficient data polling.
Remote Software Support: Facilitates Ethernet communication for 3500 Rack Configuration and Data Acquisition software (System 1).
Hot-Swap Capability: Can be installed or removed from the rear of the rack without powering down the entire machinery protection system.
Diagnostic Indicators: Works with the front-panel LEDs of the 3500/92 to provide visual feedback on TX/RX (transmit/receive) activity and module health.
Harsh Environment Protection: Built to withstand industrial conditions, with options often including G3 conformal coating for corrosion resistance.
