Description

Product Overview

The Bently Nevada 3500/50M-01-00 286566-02 is a dual-channel tachometer module for 3500 monitoring systems. It measures speed, zero speed, and rotor acceleration on turbines, compressors, and pumps using proximity probes or magnetic pickups.

Technical Configuration

3500/50M – Tachometer Module.
-01 – I/O module with internal terminations.
-00 – No agency approval.
Accepts up to two transducer inputs. Supports 1 to 255 events per revolution, max full scale 99,999 rpm, max input frequency 20 kHz.

Technical Specifications

Input Signal Range +10.0 V to -24.0 V
Input Impedance 20 kΩ (standard) / 40 kΩ (TMR) / 7.15 kΩ (Internal Barrier)
Transducer Supply 24 Vdc, 40 mA max per channel
Max Input Frequency 20 kHz
Max Full Scale RPM 99,999 rpm
RPM Accuracy (<100 rpm) ±0.1 rpm
RPM Accuracy (100-10,000 rpm) ±1 rpm
RPM Accuracy (10,000-99,999 rpm) ±0.01% of true speed
RPM/Min Accuracy ±20 rpm/min
Recorder Output +4 to +20 mA, 0 to 600 Ω load
Resolution 0.3662 µA/bit ±0.25% (room temp)
Power Consumption 5.8 W typical
Dimensions (HxWxD) 241.3 x 24.4 x 241.8 mm (9.50 x 0.96 x 9.52 in)
Weight 0.82 kg (1.8 lb)
Rack Space 1 full-height front slot

Installation Guide

Mount in any full-height front slot of a 3500 rack. For proximity probes, set the Auto Threshold for inputs above 0.0167 Hz. For magnetic pickups, minimum input frequency is 3.3 Hz. Manual threshold adjustable from +9.5 Vdc to -23.5 Vdc with 500 mV peak-to-peak minimum amplitude. Use shielded cables for field wiring.

Engineering Advantages

High accuracy across the full speed range (±0.01% above 10,000 rpm). Dual-channel input with independent recorder outputs. Short-circuit protected buffered transducer outputs on front coaxial connectors. Supports advanced rotor acceleration and zero speed detection with programmable alarm delays (1-60 sec).

Technical FAQs

Q1: What transducers are compatible?
A1: Accepts up to two proximity probe transducers or passive magnetic pickups. For magnetic pickups, the minimum input frequency is 3.3 Hz.

Q2: How to set the trigger threshold?
A2: Use Auto Threshold for signals above 0.0167 Hz (1 rpm at 1 event/rev). Manual threshold adjustable from +9.5 Vdc to -23.5 Vdc with minimum 500 mV peak-to-peak amplitude.

Q3: What are the firmware requirements for integration?
A3: Requires 3500/22M Firmware Rev 1.70, Configuration Software v4.20+, Data Acquisition v2.52+, and 3500/50M Firmware Rev 5.30+. Not compatible with 3500/20 racks.
