ACT Series Panel Tachometers From Monarch Instruments

ACT Series, ACT-1B Panel Tachometer, ACT-3X Panel Tachometer, Panel, Tachometers, Tachometer, Monarch, InstrumentThe ACT-1B Panel Tachometer can be factory configured to meet your specifications or user configured on site with the optional USB Programming Cable and Software

The ACT-3X Panel 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 120/240Vac input power or from 12 or 24Vdc input power (optional). Programming is easily performed through the 5 front panel push buttons or using the optional PM Remote Software. Set up for single channel monitoring or use the auxiliary second channel input. Programmable scale factor with menu selection for multiple pulses per revolution, linear rates, totalization, single event trip speeds and rate of change in rpm. A TTL pulse repeater output is standard.
