Monarch Instruments ACT-3X Panel Mount Tachometer & Totalizer

ACT-3X Series**

The Monarch Instruments ACT-3X Panel Mount Tachometer is a powerful NIST calibrated fully programmable tachometer and totalizer. It accepts inputs from all Monarch speed sensors or from any standard TTL generating device. The unit operates from 120/240 ACV input power or from 12 or 24 DCV input power (optional). Programming is easily performed through the 5 front panel push buttons or using the free downloadable PM Remote Software. Set up for single channel monitoring. Programmable scale factor with menu selection for multiple pulses per revolution, linear rates, totalization, single event trip speeds (using auxiliary input) and rate of change in RPM. A TTL pulse repeater output is standard.
