Controllers MELSEC iQ-R Series Product features -High-speed counter, Channel isolated pulse input, Flexible high-speed I/O control-
Channel isolated pulse input module
The channel isolated pulse input module is capable of up to 30k pulse/s for the DC input.
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
