Overview
The Bently Nevada 2155/40-02 TDISecure Communication Processor is a next-generation data acquisition module designed to upgrade legacy vibration monitoring architectures, including systems that previously relied on TDXnet processors. It enables secure, real-time capture of both dynamic machinery vibration data and process variable inputs, ensuring high-integrity diagnostics for critical rotating assets.
The TDISecure supports parallel sampling for up to 24 dynamic channels with bandwidth from DC to 30 kHz, along with 24 configurable process inputs (4–20 mA or DC voltage). It connects seamlessly to System 1 via Ethernet and provides Modbus serial communications for flexible integration.
In addition, the processor isolates data acquisition from protection functions, strengthening cybersecurity and improving system reliability. Designed with a compact industrial enclosure, it is ideal for both new installations and retrofit modernization of installed Bently Nevada monitoring systems.
