Quick Detail

Description

The 3500/53M 286566-01 Overspeed Detection Module monitors high-speed machinery for overspeed conditions within Bently Nevada 3500 Series systems. Accepting a single signal from proximity probes or magnetic pickups, the 3500/53M 286566-01 supports an input range of +10 V to -24 V and 20 kΩ impedance. Typical power draw is 8 W. The module provides 4–20 mA recorder output proportional to full-scale rpm, with 0.3662 µA per bit resolution and updates every 100 ms. SPDT relays handle under-alert, over-alert, and danger (overspeed) setpoints configurable via software, responding in less than 30 ms above 300 Hz. Front panel LEDs indicate OK, bypass, test, and alarm status. Transducer supply delivers -24 Vdc at 40 mA, output impedance is 550 Ω. Multiple 3500/53M 286566-01 modules can be arranged in 2-of-2 or 2-of-3 voting configurations in a 3500 rack with redundant power, enabling automated alarms and shutdowns. Operating range covers -30°C to +65°C with 95% non-condensing humidity, ensuring integration into automated overspeed protection systems for precise speed monitoring.

Applications

Monitor Turbine Shaft Speed
The 3500/53M 286566-01 uses signals from proximity probes or magnetic pickups to monitor turbine shaft rpm. With 4–20 mA output and 0.3662 µA per bit resolution, operators can track real-time speed and trigger automated overspeed alarms.

Automated Pump and Compressor Protection
The 3500/53M 286566-01 activates SPDT relays for under-alert, over-alert, and danger setpoints. Alarm response is under 30 ms above 300 Hz, enabling immediate automated shutdown of pumps and compressors.

Integrate into Voting Logic Systems
Multiple 3500/53M 286566-01 modules can form 2-of-2 or 2-of-3 voting arrangements in a 3500 rack with redundant power. This allows automated decision-making for critical overspeed shutdowns in high-speed machinery.

Record and Log Speed Data for Control Systems
The 3500/53M 286566-01 provides high-resolution recorder outputs updated every 100 ms. This data feeds directly into SCADA or DCS systems for automated speed monitoring and historical logging.

Specifications

Competitive Advantage

Fast Overspeed Response
With alarm delay below 30 ms above 300 Hz, the 3500/53M 286566-01 ensures immediate relay activation for automated machinery protection.

Direct Rack Integration
The 3500/53M 286566-01 installs directly into Bently Nevada 3500 racks with redundant power, supporting automated operations without extra configuration.

Supports Multiple Transducers
Compatible with 3300 8 mm/16 mm Proximitor, 7200 series Proximitor, and magnetic pickups, the 3500/53M 286566-01 allows use of existing sensors without modifications.

Accurate Data Output for Automation
High-resolution 4–20 mA output and consistent update rate provide precise data for controllers, enabling automated overspeed detection and logging.

Front Panel Indicators for Quick Checks
The 3500/53M 286566-01 features LEDs for OK, bypass, test, and alarms, allowing operators to verify module function or diagnose issues quickly.
