SHD30 and SHD30-45 Speed/Time Sensors

The SHD30 and SHD30-45 are microprocessor based tachometers with hourmeter and an overspeed trip point. The trip point can be connected as either a form “c” relay output or as a normally open SCR output for alarm or shutdown on overspeed.

Features
• Normally Open and Normally Closed Overspeed Alarm or Shutdown Switch (Standard)
• RPM Data and Power Supplied by Magnetic Pickup or Capacitor Discharge (CD) Ignition
• Accurate to ±0.5% of Display Reading
• Hours Can Be Preset and Reset to Zero
• Approved for Class I, Division 2, Groups C & D Hazardous Areas
