The 3500-50M 286566-02 288062-02 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 setpoints and generates alarms when the setpoints are violated.

Featuring a high-precision time-base processing chip, the module ensures microsecond-level, latency-free response even during high-dynamic speed phases such as machinery startup, coast-down, or severe load fluctuations. The highly isolated buffered outputs on the rear 288062-02 I/O module not only securely feed premium pulse signals into Bently Nevada System 1™ software, but also integrate seamlessly with third-party DCS, PLC, or SCADA networks. This effectively bridges the data gap between field-level hardware and enterprise-level management systems.
Furthermore, by fully recording every single startup and coast-down profile of the shaft, it provides indispensable, unalterable baseline big data for predictive maintenance (PdM), Asset Performance Management (APM), and Root Cause Analysis (RCA) of machinery faults.

Thermal Power Generation
Monitors the real-time speed and rotor acceleration of steam turbine generators and large boiler feedwater pumps, providing critical overspeed protection interlocks.
Petrochemical & Refining
Used for speed condition monitoring and zero-speed permissive logic of centrifugal compressors, hydrocracking pumps, and high-power axial fans in hazardous areas.
Hydroelectric Power Generation
Monitors the low-speed turning gear operations of hydro-generator shafts and provides runaway speed alarms during sudden load-rejection events.
Wind Power Generation
Monitors the speed of the wind turbine main shaft and the high-speed side of doubly-fed generators to optimize blade pitch control and prevent runaway overspeed.
Iron & Steel Metallurgy
Utilized for speed and reverse rotation detection on blast furnace Top Gas Recovery Turbine (TRT) blowers and heavy-duty main drive shafts of hot rolling mills.
Mining & Mineral Processing
Monitors the speed of large drive motors for semi-autogenous (SAG) mills, ball mills, and heavy-duty conveyors, providing zero-speed interlocking and mechanical jam protection.
Set the internal jumpers on the I/O module to match the sensor type. Route signal cables separately from high-voltage lines. Always bypass trip logics before hot-swapping the main board to prevent accidental shutdowns.
Technical notes
Installed at the rear of the 3500 rack directly behind the main module, this board facilitates all field physical wiring. It provides the sensor power supply, receives raw pulse signals from transducers, hosts the internal jumpers for sensor type selection, and delivers conditioned recorder outputs (4-20mA or 0-10V) alongside Keyphasor buffered signals.
3500-50M 286566-02 288062-02 is a Tachometer Module.
What is the difference between 286566-02 and 288062-02?
286566-02 is the main module inserted into the front of the rack; 288062-02 is the I/O module installed at the rear.
How many sensor signals can the 3500-50M receive?
The standard module provides 2 fully functional channels to connect 2 independent tachometer sensor inputs.
Does the 3500-50M 286566-02 288062-02 support hot-swapping?
Yes. The main module can be safely removed or inserted while the system rack is powered, without damaging the hardware.
How long will it take for my product to arrive?
