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.
It 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 is used with magnetic sensors as a signal source. However, it 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.
