The BENTLY 136719-01 is a critical interface module that enables the 3500/92 Communication Gateway to interact with the outside world. Located at the rear of the 3500 rack, it provides the physical ports required for high-speed Ethernet and serial communications. This module is the "physical layer" that allows the 3500 rack to act as a data server for plant-wide monitoring networks.
Equipped with RJ45 Ethernet ports and serial connectors, the 136719-01 supports multiple industrial communication protocols, most notably Modbus TCP/IP and Modbus RTU. This allows the 3500 system to integrate seamlessly with both modern and legacy Distributed Control Systems (DCS). The module handles the electrical signal conditioning required for long-distance data transmission in electrically noisy industrial environments.

The 136719-01 is engineered for the high data throughput required to stream vibration data from a full 3500 rack. Its hardware is designed for low latency, ensuring that the plant operators receive machine status updates in near real-time. This high speed is critical for modern plant operations where vibration levels are often used as an input for automated control loops or efficiency optimization.
A key design feature of the 136719-01 is its electrical isolation. It protects the 3500 rack's internal bus from voltage transients on the plant network. Additionally, it facilitates secure communication by separating the diagnostic network (System 1) from the control network (DCS). This separation ensures that a network issue on the plant floor does not blind the diagnostic team or vice-versa.
The BENTLY 136719-01 is built to industrial standards, featuring high-quality components that resist oxidation and thermal stress. Its robust construction ensures that it remains functional in environments ranging from desert oil fields to humid coastal power plants. As a trusted part of the Bently Nevada 3500 series, it is a primary choice for engineers looking to integrate machinery protection with plant-wide intelligence.
