The TACHTROL 30 computing tachometer is a dual channel instrument. It measures input frequency and converts the resulting quantities to an analog output, utility RS485 communication, 2 solid state & 2 mechanical relay functions and digital display.
The TACHTROL 10 computing tachometer is the same as the TACHTROL 30 but excludes the solid state relays, analog output and the utility RS485 function.
These instruments will accept a wide range of AC or DC power and have greatly improved accuracy, processing speed and response time. They can be used in rate, period or counter mode.
The simplified programming can be done in the field or office via PC/Windows-based TACHLINK or through the integrated display/membrane panel. Security mode guarantees unauthorized access to programming changes.
Typically, the new TACHTROL 30 or 10 are used with magnetic sensors as a signal source. However, they may receive sine wave or square wave TTL signals from any frequency source including phase-shifted frequencies from bi-directional Hall sensors to indicate change in direction.
