BENTLY 3500/50 286566-02 Tachometer module

BENTLY 3500/50 286566-02 is a tachometer module manufactured by Bently Nevada. Below is its comprehensive detailed information:

1. Product Overview

This is a 2-channel module that accepts input signals from proximity probes or magnetic pickups to determine shaft speed, rotor acceleration, or rotor direction. The module compares measured values with user-programmable alarm setpoints and generates an alarm when the measured values violate these setpoints.

2. Programming & Configuration

It can be programmed using the 3500 Frame Configuration Software and configured into the following types:

Speed monitoring, setpoint alarms, and speed band alarms;
Speed monitoring, setpoint alarms, and zero-speed indication;
Speed monitoring, setpoint alarms, and rotor acceleration alarms;
Speed monitoring, setpoint alarms, and reverse rotation notification.

3. Technical Parameters

Input Signal Range: +10.0 V to -24.0 V
Input Impedance: Standard 20 kΩ; TMR (Thermistor) 40 kΩ; Internal barrier 7.15 kΩ
Power Consumption: Typical value 5.8 watts
Front-Panel Indicators: LED indicators for OK, TX/RX, and Bypass status
Output Impedance: 550 Ω

4. Product Features

Peak Hold Function: Can store the maximum speed reached by the machine, and this speed can be reset by the user.
Configurable Alarm Outputs: Supports customizable alarm output settings to adapt to different safety monitoring needs.
Modbus RTU Interface: Enables seamless communication with external control systems (e.g., DCS, PLC) for data transmission and remote monitoring.
DIN Rail Mounting: Adopts DIN rail mounting method, facilitating installation and on-site maintenance.
