Description
Part Number: 133442-01
Manufacturer: Bently Nevada
Series: 3500
Product Type: I/O Module with Internal Terminations
Country of Origin: United States (USA)
133442-01 is an I/O Module with Internal Terminations developed by Bently Nevada. It is a part of the 3500/55M Tachometer system. In order to detect shaft rotational speed, rotor acceleration, or rotor direction, the Tachometer Module, a 2-channel module, accepts input from proximity probes or magnetic pickups. When the setpoints are breached, the module generates alarms and compares these data to user-programmable alarm setpoints.
133442-01 Features
- The Tachometer Module is a two-channel module that uses proximity probes or magnetic pickups to determine shaft rotative speed, rotor acceleration, or rotor direction. When these measurements are compared against user-programmable alarm setpoints, the module generates alarms.
- The Tachometer Module can be configured to provide conditioned Keyphasor signals to the 3500 rack's backplane for use by other monitors. As a result, there is no need for a separate Keyphasor module in the rack.
- External Termination Blocks cannot be used with Internal Termination I/O modules and should only be used with TMR I/O modules.
Compatibility
- Termination from Without Internal Termination I/O modules cannot be utilized with blocks.
As it lacks the protective redundancy and response speed required for dependable operation as a speed control or Overspeed protection system, the Tachometer Module should not be used alone or as a part of speed control or Overspeed protection system.
