  • Page 11: Introduction

    1. Introduction 1.1 General  The standard equipment of SAIA PCD process control devices already offers 1600 counting registers of 31 bits, although they can only capture frequencies up to approx. 20 Hz. Via the interrupt inputs, 1 kHz can be achieved and, with the ..H100 counting module, up to 20 kHz are possible.
