Frequency Input Module & Pulse Counter - FIM

Frequency-input-module

Racelogic's Frequency Input Module (RLVBFIM03) is a 4-channel frequency capture and pulse counter unit. It enables frequency based signals in the range of 1Hz to 20kHz to be recorded or logged by a VBOX.

The input circuit for each channel can accept a wide signal amplitude range from TTL output sensors up to the higher voltages created by inductive sensors.
This means that direct connection to ABS wheel speed sensors, RPM sensors or fuel flow sensors is possible. A dedicated fuel flow mode makes the monitoring of fuel consumption and flow rate very easy to set up and use.

The RLVBFIM03 can be configured through software to process the input frequency or pulse data to provide logged data in real units. By configuration of each channel the incoming frequency or pulse train can be easily configured into any of the following data formats:

  • Frequency (Hz)
  • RPM
  • Speed Km/h
  • Speed Mph
  • Pulse Count
  • Fuel Used (Lt/Gal)
  • Fuel Flow Rate (Lt/Hr-Gal/Hr)
  • Fuel Consumption (Lt/100Km)
  • Fuel Consumption (Km/Lt MPG)

Features

  • Frequency input range 1Hz to 20KHz
  • Pulse counting mode
  • Input channels can accept direct connection to inductive sensors such as ABS or Crankshaft sensor 
  • Internal scale and offset to provide SI units from sensors
  • Modes for automatic calculation of RPM or wheel speed
  • BNC connection for signal input

Applications

  • ABS brake stops
  • Tyre traction testing
  • Aquaplane testing
  • Fuel flow/consumption
  • General vehicle evaluation
  • Engine monitoring (RPM)
