2. Product Description
2.1 General Function
The 3500/50 286566 – 02 is a tachometer module designed for industrial machinery monitoring. Its primary role is to accurately measure and monitor the rotational speed of shafts in various industrial equipment, such as turbines, motors, and generators. By doing so, it provides crucial data for the overall condition monitoring and control of the machinery.
2.2 Key Features

- Dual – Channel Input: It is a dual – channel module, which can accept inputs from proximity probes or magnetic pickups. This allows it to simultaneously monitor two different rotational elements or redundant sensing points for enhanced accuracy and reliability. For example, in a large – scale power generation turbine, it can receive signals from two different positions on the shaft to get a more comprehensive understanding of the shaft’s rotational behavior.
- Multi – Parameter Measurement: Besides measuring shaft speed, the module can also determine rotor acceleration and rotor direction. These additional measurements are valuable for analyzing the performance and health of the machinery. For instance, sudden changes in rotor acceleration can indicate mechanical problems such as bearing wear or unbalanced loads, while knowing the rotor direction is essential for proper operation and control of the
