The 133442-01 Tachometer I/O Module with Internal Terminals is an integral part of the Bently Nevada 3300 Series system, designed to deliver high-accuracy speed and phase reference measurements for rotating machinery. It works in conjunction with the tachometer monitor module to detect rotational speed and provide critical phase reference signals for vibration analysis and machinery diagnostics.

This module is engineered for use with magnetic pickups, proximity probes, and other pulse-generating speed sensors to convert mechanical rotation into reliable electrical signals. The internal terminal version (133442-01) offers a compact design with secure wiring connections, reducing installation complexity and ensuring signal integrity even in harsh industrial environments.

Once installed in the I/O module bay of the monitoring system rack, the 133442-01 provides essential outputs used in machinery protection applications, including speed alarms, phase triggering, overspeed protection, and startup/shutdown sequencing. It plays a critical role in ensuring machines operate within safe limits, especially in high-speed equipment such as turbines, compressors, and large motors.

With its rugged design, wide sensor compatibility, and precise signal processing, the Bently Nevada 133442-01 ensures dependable performance and contributes to long-term machinery health monitoring strategies. It is widely used in industries such as power generation, oil & gas, petrochemicals, steel plants, and manufacturing where unplanned downtime is costly and unacceptable.

Trusted across industries such as oil & gas, power generation, chemical processing, and manufacturing, this I/O module enhances the reliability of your vibration monitoring system and helps reduce the risk of unexpected downtime.
