SAIA Burgess PCD2.H110 Universal Counting and Measurement Module

SAIA Burgess PCD2.H110 Universal Counting and Measurement Module

Product basic positioning and core values

PCD2.H110 is an industrial grade universal counting and measurement module launched by SAIA Burgess Electronics. Its core positioning is to provide highly integrated counting and measurement solutions for the PCD1/PCD2 series controllers, filling the functional gap of high-frequency counting and multi type measurement in basic controllers. The core value of the product lies in the integration of four major functions (counting, frequency, cycle, pulse length measurement) in a single module, supporting parallel connection of multiple modules (up to 16 for PCD2 and up to 4 for PCD1), and possessing industrial grade reliability (wide temperature operation, anti-interference), which can significantly reduce the hardware complexity and cost of industrial automation systems. It is widely used in automation assembly, motion control, material sorting, flow detection and other scenarios.

Typical application scenarios and examples

The document provides three core application examples, covering three major scenarios: counting, motion control, and measurement

Programmable counter (GRAFTEC programming): Set the preset value through the BCD switch, the counter starts counting from 0, and after reaching the preset value, the CCO output flips, suitable for quantitative counting of materials;

Incremental encoder motion control: adapted to a 2-phase incremental encoder with 500 pulses per revolution, achieving acceleration uniform speed deceleration positioning control of the slide table, supporting reciprocating motion, suitable for axis control scenarios in automated assembly lines;
