Channel isolated pulse input module

The channel isolated pulse input module is capable of up to 30k pulse/s for the DC input.

RD60P8-G

Features<sup>Multiple measurement functions and channel isolation are ideal for process control applications</sup>

  • Multiple measurements
  • Channel isolation
  • One module can measure the number of input pulse data for speed, rotation speed, and instantaneous flow rate and also measure quantity, length, and cumulative flow rate of 8 channels maximum
  • Galvanic channel isolation is included which prevents noise interference making it ideal for process control applications
