BENTLY 3500/20-01-02-00
Product Overview
The BENTLY 3500/20-01-02-00 is a Rack Interface Module (RIM) designed for Bently Nevada’s 3500 series machinery protection systems. As a critical component, it serves as the central hub for configuring and communicating with the 3500 rack, enabling integration with external systems and ensuring seamless data exchange between monitoring modules. Installed in Slot 1 of the BENTLY 3500/05 system rack, it supports communication protocols like TDXNET, DDIX, and RS232/RS422, facilitating real-time data transmission to host computers or distributed control systems (DCS). While superseded by newer models like the BENTLY 3500/22M Transient Data Interface Module, the 3500/20-01-02-00 represents an intermediate iteration optimized for legacy system compatibility with enhanced I/O capabilities compared to its predecessor, the 3500/20-01-00-00 .
Engineered with a compact half-height form factor, the 3500/20-01-02-00 supports both single and triple modular redundancy (TMR) configurations. Its -40°C to +85°C storage temperature range and IP54-rated enclosure make it suitable for harsh industrial environments, including offshore platforms and chemical processing plants. The module’s galvanic isolation and surge protection align with API 670 standards, ensuring reliable operation in safety-critical applications plcdcspro.com.

Key Features and Advantages
Enhanced Communication Capabilities:
The 3500/20-01-02-00 builds on its predecessor by supporting RS232/RS422 interfaces via optional I/O modules (e.g., 125768-01), enabling compatibility with legacy systems that require serial communication. This makes it particularly valuable in retrofitting projects where Ethernet connectivity is not yet feasible .
