BENTLY 60R/CHA02 System Chassis / Rack Enclosure
The BENTLY 60R/CHA02 is a System Chassis or Rack Enclosure designed specifically to house and interconnect modules of the Bently Nevada 3300 series machinery condition monitoring and protection system. This 3U industrial panel-mounted chassis serves as the physical and electrical backbone for building a complete monitoring station, providing a standardized, modular framework for critical rotating equipment protection across all heavy industries. Manufactured by Bently Nevada, now part of Baker Hughes, the CHA02 chassis is the standard enclosure for deploying centralized monitoring solutions for assets such as turbines, compressors, and large pumps.
Technical Specifications
The BENTLY 60R/CHA02 is a 3U panel mount chassis compatible with the Bently Nevada 3300 series, particularly the 3300/20 Enhanced Machinery Protection System (EMPS). The chassis accommodates a fixed number of module slots, typically 6 or 8 slots, including dedicated positions for a power supply module such as the 60R/PNL01 and a communication interface module such as the 60R/CMM01 or 60R/PIM01. Slots are keyed or designated for specific module types, including power supply slot, communication slots, and general monitor slots for vibration monitors such as the 3300/46, analog input modules such as the 60R/INP01, and relay modules.

Design and Construction
The 60R/CHA02 is more than a metal housing; it is an integrated assembly that includes a printed circuit board backplane. This multi-layer PCB backplane carries the DC power rails such as +24V and ±15V from the power supply module to every slot, distributing clean DC voltage to all installed modules. The backplane also facilitates high-speed digital communication between modules via a proprietary high-speed serial bus, allowing modules to share data, synchronize clocks, and be configured as a unified system. The backplane may provide physical addressing for modules, enabling the system to identify and communicate with each installed component.
Features and Installation
The chassis provides features for secure mounting in a control panel, proper grounding, and cable entry points with strain relief for field wiring connected to the front of the modules. The 3U form factor complies with standard industrial rack mounting dimensions, enabling integration into existing equipment racks. The chassis design ensures proper mechanical and electrical mating of modules, with slot keying preventing incorrect module insertion. Implementing a 60R/CHA02 chassis is the foundational first step in deploying a centralized, rack-mounted 3300 monitoring solution for critical assets in power generation, oil and gas, petrochemical, and other heavy industries.
Applications
The BENTLY 60R/CHA02 is deployed in machinery protection and condition monitoring applications requiring centralized rack mounting of monitoring modules. Typical applications include steam turbine and gas turbine monitoring systems requiring multiple vibration and position measurement channels, compressor protection systems in natural gas transmission facilities, and large pump monitoring in water treatment and industrial facilities. The chassis is also used in power generation plants, petrochemical refineries, and any installation where Bently Nevada 3300 series monitoring modules must be housed in a standardized, maintainable enclosure with integrated power distribution and inter-module communication.
