Description Specifications Description This item has been discontinued and replaced by the T77530-70.The TACHPAK 10 is a computing speed switch that also measures input frequency. This dual channel device does not include the function of converting measured quantities to solid state relays, analog output, or the utility RS485 communication.The TACHPAK 30 and TACHPAK 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.Included FeaturesQuicker Response Time-706 ms (analog), 16.5 ms (mech. Relays), 2ms (dig.
