Output & System Parameters
Power Supply: 24 V DC (chassis backplane supply)
Power Consumption: 5.8 W (typical)
Output Interface: Transmits speed, acceleration, direction data and alarm signals to the 3500 backplane; supports peak hold for maximum speed/reverse speed recording
System Communication: Integrates with 3500 chassis communication modules; compatible with industrial protocols via backplane (Modbus, RS485, etc., dependent on chassis configuration)
Key Features
- 2-channel tachometer module for simultaneous monitoring of shaft speed, rotor acceleration and rotor direction
- User-configurable operating modes: speed monitoring with alarm setpoints, zero-speed indication, acceleration alarm, or reverse direction detection
- Onboard peak hold function stores maximum speed/reverse speed values for machine performance analysis
- Capable of providing keyphasor signals to other 3500 monitors, eliminating the need for a separate keyphasor module
- Built-in diagnostic circuitry and self-test capabilities for rapid fault detection and reduced maintenance downtime
- Hot-swappable design for easy replacement without full system shutdown, ideal for continuous-process industries
- Rugged industrial construction with wide operating temperature range and high electromagnetic interference (EMI) resistance, suitable for power generation, oil & gas, chemical processing, pulp & paper, and marine applications
- Compliant with international industrial standards for reliability and safety in critical machinery protection
