Controllers MELSEC iQ-R Series Product features -High-speed counter, Channel isolated pulse input, Flexible high-speed I/O control-

    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

    RD62P2

    Max. 200k pulse/s 2-channel Coincidence output (sink)

    RD62P2E

    Max. 200k pulse/s 2-channel Coincidence output (source)

    For line driver

    RD62D2

    Max. 8M pulse/s 2-channel Coincidence output (sink)

    Features <sup>High-accuracy pulse measurement </sup>

    • 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

    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
