MELSEC iQ-R Series

High-speed counter module

The high-speed counter modules are capable of up to 200k pulse/s for the DC input, and up to 8M pulse/s for differential input. The movement amount can also be measured when used with a rotary encoder, linear encoder, digital gage, etc. In addition, a signal is output when a specified position is reached.

  • For open collector/voltage output

    • RD62P2Max. 200k pulse/s2-channelCoincidence output (sink)
    • RD62P2EMax. 200k pulse/s2-channelCoincidence output (source)

  • For line driver

    • RD62D2Max. 8M pulse/s2-channelCoincidence output (sink)

High-accuracy pulse measurement

  • Measurement resolution 100 ns
  • High-accuracy measurement
  • The pulse measurement function enables measuring of the pulse cycle, which is ideal for applications where workpiece length and speed need to be detected
  • In the food and beverage industry, the size and speed of bottles traveling on the conveyor are easily measured using proximity sensors
  • Wind turbine speed can be measured from the pulse interval

High-accuracy pulse measurement

Smooth operation with PWM output

  • Max. 200 kHz
  • Min. 100 ns pulse width
  • The PWM output frequency can support up to 200 kHz with a minimum 100 ns pulse width (proportion to “on” time) during the required duty cycle
  • The set values can be changed during operation without having to stop the system, such as in industrial-scale fan control
