3500/50M Tachometer Module |
🔹 Description
The 3500/50M Tachometer Module is a 2-channel module that processes input from proximity probes or magnetic pickups to determine:
• Shaft rotative speed
• Rotor acceleration
• Rotor direction
The module compares these measurements against user-programmable alarm setpoints and generates alarms when limits are exceeded.
