Technical Specifications Signal Type: Magnetic pickup pulse signal Terminal: Screw clamping terminals Built-in Filter: Low pass filter for pulse signal Surge Protection: Transient voltage suppression Operating Temperature: -40℃ ~ +70℃ Mounting: DIN rail mounting Isolation: Channel to ground isolation
Functional Features Centralized wiring for speed probe and Keyphasor probe. Built-in filter to suppress high frequency noise of pulse signal. Surge protection to absorb field transient voltage pulse. Screw terminals for convenient field wiring and maintenance. Clear channel marking to distinguish tachometer and keyphasor channels. DIN rail installation inside control cabinet.
Application Scenarios Wiring terminal for Bently speed probe and Keyphasor probe. Steam turbine overspeed protection system signal termination. Compressor rotational speed and phase reference signal wiring. Power plant generator rotating speed monitoring cabinet. Petrochemical plant rotating machinery Keyphasor signal processing.
Structural Characteristics Flame retardant plastic housing with DIN rail clip. Screw type terminal blocks for pulse signal wiring. Internal PCB equipped with filter and surge suppression components. Channel identification printed on front panel. Locking buckle for fixing on DIN rail.
Working Principle Pulse signal from magnetic speed probe or Keyphasor probe enters the terminal module. The built-in low-pass filter removes high-frequency electromagnetic noise. Surge protection components absorb abnormal high voltage transient pulse. Processed pulse signal is transmitted through connecting cable to speed module or Keyphasor module inside rack.
Installation Requirements Install module on standard DIN rail in control cabinet. Lock DIN rail clip to prevent sliding. Use shielded twisted pair cable for field probe wiring. Route signal cable separately from high voltage power cable. Tighten terminal screws with proper torque to avoid poor contact. Connect shield ground at single point according to wiring specification.
