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 Features
  • Quicker Response Time-706 ms (analog), 16.5 ms (mech. Relays), 2ms (dig. Relays)
  • Higher Level of Accuracy - 0.1% (analog), 0.005% (relays)
  • Field Programmable - With TACHLINK or TACHTROL plus
  • Digital Configuration - Approaches real time
  • Analog Outputs - 0 -20 mA, 4-20 mA, -20 to 0 to +20 mA
  • Relays - (2) mechanical Form C, 6 A @ 277 Vac, (2) solid state Form A 0.4 A @ 60 Vac or DC
  • Digital Display -Will accept (8) TACHTROL plus remote displays
  • 9 Computed Functions
