SHD30 (20700196): Digital Tachometer and Hourmeter
SHD30(240).jpg The SHD30 is a microprocessor-based digital tachometer with an 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. The five-digit, liquid crystal display is updated every second.

The SHD30 receives power and RPM data from either a magnetic pickup or a capacitor discharge (CD) ignition. The hourmeter is adjustable to a preset time and resettable to zero. Should power be lost, on-board batteries maintain the run hours display and allow for resetting the overspeed relay output.

Approved for Class I, Division 2, Groups C & D hazardous areas.
