Product Description

The 3500/42 (128229-01) is a four-channel Proximitor/Seismic I/O module designed for use with the Bently Nevada 3500/42M monitor. This specific version features internal terminations, which allows for direct field wiring to the back of the 3500 rack without the requirement for external terminal blocks or specialized interface cables. It serves as the physical interface between vibration sensors and the monitoring system, providing high-fidelity signal conditioning for machinery protection.

Each of the four channels on the 128229-01 can be independently configured to support a variety of transducer types, including proximity probes, accelerometers, and Velomitors. The module is engineered to provide robust power to the transducers and return accurate dynamic signals to the monitor for vibration amplitude, axial position, and speed measurements. Its rugged design ensures long-term reliability in demanding industrial environments where electromagnetic interference and temperature fluctuations are common.
