Recently, a client asked me which A-B Micro PLC’s supported HSC and PTO functions, as well as how fast each is. Below is the results of my research:

Note: The below are best case based on choosing the DC I/O model of the Micro with the most high speed digital inputs and outputs.

Micro800 family support for PTO outputs and HSC inputs.

Micro 830Select Micro850 models support:

  • Six high-speed 100 kHz counter inputs (HSC)
  • Three high-speed 100 kHz pulse train outputs (PTO)

Select Micro830 models support:

  • Six high-speed 100 kHz counter inputs (HSC)
  • Three high-speed 100 kHz pulse train outputs (PTO)

MicroLogix family support for PTO outputs and HSC inputs.

Select MicroLogix 1400 models support:

  • MicroLogix FamilyThree high-speed 100 kHz counter inputs (HSC)
  • Three high-speed 100 kHz pulse train outputs (PTO)

Select MicroLogix 1100 models support:

  • One high-speed 40 kHz counter input (HSC)
  • Two high-speed 40 kHz pulse train outputs (PTO)

Select MicroLogix 1500 models support:

  • MicroLogix Family Featured ImageTwo high-speed 20 kHz counter inputs (HSC)
  • Two high-speed 20 kHz pulse train outputs (PTO)

Select MicroLogix 1200 models support:

  • One high-speed 20 kHz counter input (HSC)
  • One high-speed 20 kHz pulse train output (PTO)

Select MicroLogix 1000 models support:

  • One high-speed 6.6 kHz counter input (HSC)

I hope you find the above comparison is helpful. If you have any comments, questions, or corrections please don’t hesitate to share them by using the “Leave a reply” form at the bottom of this page.
