3BHE026866R0001 ABB Speed Module

Signal Conversion: It converts these raw sensor signals .

Accurate Speed Calculation: It precisely calculates the actual speed (e.g., RPM, Hz, meters/second) of the rotating equipment.

Feedback for Control Loops: The accurate speed data it provides is crucial for closed-loop speed control systems. The controller (e.g., a PLC or DCS) uses this feedback to compare the actual speed with the desired setpoint and adjust the output (e.g., to a variable frequency drive) to maintain the target speed.

Over-speed/Under-speed Detection: It can detect if the monitored equipment is operating outside of its acceptable speed range, triggering alarms or safety shutdowns if necessary.

Synchronization: For multi-axis systems or processes requiring synchronized motion, speed modules provide the necessary feedback to ensure different parts of a machine operate in harmony.

Fault Detection: By monitoring speed, it can help detect mechanical issues, overloads, or other anomalies in the equipment, often before they lead to significant damage.
