Product Description

Overview

The Bently Nevada 2155/40 TDISecure Communication Processor is a high-performance interface module for industrial machinery monitoring. Designed to bridge Bently Nevada 3500 series hardware with software platforms such as System 1, it provides secure, high-fidelity data acquisition while isolating monitoring functions from critical protection systems.

Its TDISecure architecture emphasizes cybersecurity, ensuring that transient and steady-state data can be collected without compromising the integrity of machine protection logic. This module is ideal for high-value rotating assets where precise vibration, process, and speed data are critical.

Product Variants

• 2155/40-01: AC input, 100–240 VAC

• 2155/40-02: DC input, 20–36 VDC
