Description

Designed for integration within the 3500 Machinery Protection System, the 3500/50-04-CN delivers high-reliability tachometer measurements and speed monitoring capabilities. This module processes input signals from various speed sensors to provide rotational speed, acceleration, zero speed, and reverse rotation parameters, serving as a critical component in rotating machinery protection.

The 3500/50-04-CN configuration features an I/O module equipped with internal barriers and internal terminations (Option 04). This integration allows direct interfaces to transducers installed in hazardous environments without requiring auxiliary external barrier hardware. The country-specific agency approval (CN) ensures adherence to regional safety standards for industrial operations.

Features

Dual-channel speed monitoring and phase reference capability.
Integrated safety barriers for direct hazardous area transducer connection.
Internal terminations to streamline field wiring and optimize cabinet space.
Real-time configuration of speed, acceleration, and peak hold parameters via 3500 software.
Continuous self-test and diagnostic coverage for enhanced system reliability.

Applications

Steam, gas, and hydro turbine speed protection.
Centrifugal and axial compressor shaft monitoring.
Generator speed and phase reference monitoring.
Over-speed, zero-speed, and reverse-rotation detection in chemical and hydrocarbon processes.

Installation Guidelines

Prior to installing or servicing the 3500/50-04-CN module, ensure that local field wiring protocols for hazardous areas are fully met. The internal safety barriers rely on direct, low-impedance grounding paths to ensure intrinsic safety protection. Maintain routing separation between intrinsically safe transducer wiring and non-intrinsically safe cabling within the enclosure.

What is the function of the internal barriers on the Bently Nevada 3500/50-04-CN?

The internal barriers (Option 04) provide intrinsically safe connections to speed transducers located in hazardous areas, eliminating the need for separate external safety barriers.

What does the CN designator indicate in the part number 3500/50-04-CN?

The CN designator indicates country-specific agency approvals, typically used for local regional compliance in hazardous area installations.

Can the 3500/50-04-CN module handle phase reference inputs?

Yes, the tachometer module is capable of processing signals to determine phase reference, rotational speed, and zero speed.
