The Bently Nevada 3500/50M Tachometer Module is a 2-channel module that accepts input from proximity probes or magnetic pickups to determine shaft rotative speed, rotor acceleration, or rotor direction. The module compares these measurements against user-programmable alarm set points and generates alarms when the set points are violated.
The 3500/50M Tachometer Module is programmed using the 3500 Rack Configuration software. The following configuration options are available:
Accepts two transducer signals
Input signal range +10.0 V to -24.0 V
Input impedance:20 k Ω (standard)
40 k Ω (TMR)
7.15 k Ω (Internal Barrier)
Power consumption: 5.8 watts, typical
Front panel LEDs: OK, TX/RX, Bypass
Output impedance 550 Ω
