Function and Working Principle
The 3500/53 (133388-01 + 133396-01) operates as an integrated overspeed monitoring solution:
- Overspeed Detection Module (133388-01):
- Monitors real-time RPM signals from tachometer sensors
- Compares speed to predefined overspeed setpoints
- Triggers alarms, relays, or control system notifications on overspeed
- I/O Module (133396-01):
- Routes and conditions the speed signals from sensors to the overspeed module
- Ensures reliable communication with monitoring and control systems
- Provides interface for multiple signal types and outputs
The combination ensures precise monitoring, signal integrity, and fast response in critical applications.
