The TACHPAK 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 and 2 mechanical relay functions.
The TACHPAK 10 computing speed switch is the same as the TACHPAK 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 with the addition of a TACHTROL plus remote display. Security mode guarantees unauthorized access to programming changes.
Typically, the new TACHPAK 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.
