Description
1. Product Overview
The Bently Nevada 133388-01 is a dual-communication Transient Data Interface (TDI) I/O Module designed for the 3500/22M system. Installed in the rear slot of the 3500 rack, this module provides the comprehensive physical connectivity required to bridge the machinery protection rack with external diagnostic environments.
Unlike standard single-protocol I/O modules, the 133388-01 supports both Ethernet (for high-speed data streaming to System 1® software) and Serial (RS232/RS485) communication (for integration with DCS or PLC via Modbus). It is the ideal choice for facilities requiring versatile data access and high-resolution transient event capturing.
Key Applications:
- Multi-Protocol Communication: Simultaneous support for Ethernet and Serial data paths.
- Advanced Diagnostics: Essential for transmitting high-speed vibration data to diagnostic workstations.
- System Integration: Connects the 3500 rack directly to plant control systems via Modbus protocols.

7. FAQ
Q: What is the main advantage of the 133388-01 over the 133323-01?
The 133388-01 includes both Serial and Ethernet capabilities, whereas the 133323-01 only provides Ethernet. If your site requires a Modbus RTU (Serial) connection to an older PLC while simultaneously using Ethernet for System 1®, the 133388-01 is the correct choice.
Q: Does this I/O module require its own IP address?
The IP address is configured in the 3500/22M TDI Main Module, but the 133388-01 provides the physical port (RJ45) through which that network communication occurs.
Q: Can I use this module to capture transient data during a machine trip?
Yes, when used with the 3500/22M, the 133388-01 supports the transmission of high-resolution transient data (start-up, coast-down, and alarm events) to your diagnostic server.
