Description The TACHTROL 30 computing tachometer measures input frequency. This dual channel instrument also converts the resulting quantities to an analog output, utility RS485 communication, 2 solid state and 2 mechanical relay functions.
The TACHTROL 30 and TACHTROL 10 accept an extensive range of AC or DC power. These instruments have great accuracy, processing speed, response time and can be used in rate period or counter mode.
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.
