The Bently Nevada 3500/33 149992-01 is a full-height, 16-channel relay output module for the 3500 Series Machinery Protection System. Its core function is to serve as the system's "executor," converting alarm and status signals from monitor modules (e.g., vibration, position, speed monitors) into physical relay contact outputs. These outputs are used to trigger alarms, activate emergency shutdown sequences, or control external equipment, ensuring reliable protection actions even if the upper-level control system fails.

Flexible and Programmable Logic: Each of the 16 relays can be independently programmed via software using AND/OR logic. Input sources can include Alert/Danger statuses, "Not-OK" conditions, or measured variables from any monitor channel, enabling complex voting logic for tailored machine protection strategies.
Configurable Fail-Safe Operation: The module supports both failsafe (Normally Energized, NE) and non-failsafe (Normally De-energized, ND) modes, configurable in groups of four channels. This is critical for Safety Instrumented Systems (SIS), where a loss of power should result in a safe shutdown action.
Robust Industrial Design: Featuring epoxy-sealed relays and an integrated arc suppression circuit (250 Vrms), the module is built to withstand harsh industrial environments and vibration, ensuring long-term contact stability and reliability.
Comprehensive Diagnostics: Front-panel LEDs provide clear visual status for power (OK), communication (TX/RX), and individual channel alarms, enabling rapid on-site troubleshooting.
The 3500/33 is a critical component for executing protection logic in critical rotating machinery across heavy industries:
Turbomachinery Protection: Triggering emergency shutdown logic for steam and gas turbines when vibration or speed exceeds safe limits.
Compressor Control: Executing automated shutdowns or alarms for large centrifugal compressors in oil and gas applications.
Safety System Integration: Acting as the final output element in emergency shutdown (ESD) systems, driving physical lockouts or alerting operators through hardwired connections

The Bently Nevada 330105-02-12-05-02-00 is an 8 mm reverse-mount proximity probe from the 3300 XL series, engineered for non-contact vibration and position monitoring in space-constrained machinery.
The Bently Nevada 330130-085-00-00 is an 8.5-meter standard extension cable for the 3300 XL 8 mm Proximity Transducer System. It connects a 3300 XL proximity probe to its Proximitor® sensor, transmitting eddy-current displacement signals for vibration, axial position, and Keyphasor measurements on critical rotating machinery.
The Bently Nevada 21000-00-00-15-030-04-00 is a Proximity Probe Housing Assembly from the 21000 series, designed to provide a secure, environmentally sealed mounting interface for reverse-mount proximity probes on critical rotating machinery.
The Bently Nevada 330780-50-00 is a 5.0-meter Proximitor® Sensor for the 3300 XL 11 mm Proximity Transducer System. It receives signals from a 3300 XL 11 mm probe and its extension cable, conditioning them into a linear voltage output proportional to shaft displacement for radial vibration, axial thrust position, and Keyphasor measurement.
The Bently Nevada 21747-040-00 is a 4-meter Proximitor probe extension cable designed for the 3300 and 7200 Series Proximity Transducer Systems. It connects a proximity probe to its Proximitor sensor, transmitting high-frequency eddy-current displacement signals for vibration and shaft position monitoring on critical rotating machinery.
The Bently Nevada 330710-00-060-10-02-00 is a 3300 XL 11 mm Proximity Probe designed for non-contact vibration and position measurement on large, fluid-film bearing machinery. Its 11 mm tip provides a longer linear range compared to the standard 8 mm system, making it ideal for applications requiring greater measurement span, such as axial thrust position, differential expansion, and radial vibration on steam turbines, centrifugal compressors, and large pumps.
The Bently Nevada 330103-00-11-50-02-00 is a 3300 XL 8 mm proximity probe with a metric M10×1 thread and a 5.0-meter integral cable terminated with a miniature coaxial ClickLoc™ connector. This extended-reach configuration features a 110 mm overall case length and connects directly to a Proximitor® sensor without requiring an extension cable for short-run installations.
The Bently Nevada 990-10-XX-01-00 (MOD 165353-01) is a two-wire, loop-powered Vibration Transmitter designed for OEMs of centrifugal air compressors, small pumps, motors, and fans. It accepts input from a 3300 NSv proximity probe and its matching extension cable, conditioning the signal into a 4–20 mA output proportional to peak-to-peak vibration amplitude.
