Description
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 pushbuttons 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, single event trip speeds (using auxiliary input), and rate of change in RPM
Features
All models - Universal Input, non-contact operation from optical, infrared, laser, proximity, and magnetic sensors or direct TTL and 200mV to 50 Vac signals
